View Full Version : UHMW IRS Sub-Frame Mount Kits

I've had some people ask, so I'm considering making rear sub-frame mounts.

I'd make them from black UHMW rod which, among it's other properties, resists the transmission of noise and vibration.

A full set would include 8 bushings and 4 hardcoated (to prevent corrosion) aluminum sleeves.

Pricing should be somewhere around $350-$400, but that's not firm yet. I haven't yet made a set.

Is there any interest in this?

I'm interested as there are no replacements for these, not sure if the stockers are still available from Ford.

New bolts are a must, I would say. Wouldn't need to be stainless though, to keep the cost down. I had one break a few years back from driving, and had to source the entire assy as it all fell out. I think I still have one new Ford bolt if you need comparison.

Are you intending to reuse the factory large lower retainer and upper cone?

I was thinking stainless to resist corrosion in the future, I hate rust. But as I don't even know what size they are yet, I don't know if it's even possible to get them in A4 stainless, nor do I know if they'd be strong enough.

I won't know my intentions for sure, until I take my car apart, but reusing as much as possible will be the goal. And I'm not going to do that until at least one person commits to buying a set.

I'm looking for somebody to show some real interest and make a $200 deposit, and that person will get $100 off the final price. :D

If I remember correctly when I replaced mine a few years back, it is a formed steel piece covered in rubber.

When the bolt breaks they are a pain to drill out, I had to do this as I had one break for no reason. Most will cut access hole in the trunk to remove the Tnut and cut an access panel for the lower also if they break. The busings are not too easy to remove, or at least I think so, but if you had the whole subframe out that would be a different story. It will require the special Ford tool to remove the stockers, or I rigged up some all thread and black steel pipe (forming a U shape with a hole in the center for the all thread) to remove mine and install the new stock replacement. The bushing fits in a tapered opening, and there is a mushroom shaped part that pops up thru the frame.

I'll send you a deposit on a set. I do not want stainless bolts though. They need to be 10.9 grade steel. They won't rust if they are put in with proper lubrication on the shanks and locktite on the threads.

It is very common for the bolts to break on removal. We'll need to make sure that we can find the proper replacement bolts before going too deep into this one.

DLF
03-13-2010, 09:16 AM
I've got the Ford special tool to remove these.

Been doing some more research, and as far as I can tell, the three part numbers for the stock bushings are all obsolete and unavailable.

E9SZ-5D006-A (front-2 required)
E9SZ-5D006-B (rear-2 required)
E9SZ-5D001-A (retainer-4 required)

I'm somewhat concerned about removing my stock bushings, which cannot be replaced, to start development. :eek:

I agree with Dave, at least 10.9 bolts are needed.

rzimmerl
03-13-2010, 09:18 AM
The stock bolt is M12x1.75 and 125mm from the head flange to the end of the threads and 133mm to from the head flange to the tip of the bolt. McMaster Carr has SHCS grade 12.9 in 130mm length and longer, and HHCS from them grade 10.9 but only up to 120mm no longer.

Can you give me the size / pitch / length of the bolt, please?

LOL, what timing!

Fastenal has a M12-1.75 x 130mm 10.9 bolt (http://www.fastenal.com/web/products/detail.ex?sku=0122036&ucst=t).

Ford PN on the bolt is N805747-S100, its a package of 2. These are the ones I used for the rear not sure if they are the same for the front.

I believe the fronts are different. Something tells me they are a smaller bolt - like maybe even 10mm which is one reason why they break.

Interesting day. :cool:

Didn't break anything. :)

The sub-frame bolts came out, fairly easily, with a breaker bar. The front and rear bolts are the same.

There is a 70 degree taper on the bushings and in the sub-frame. My bushings are all still in pretty good shape. All the captured nuts in my frame are rust free and still green. :D

I believe that I have a design figured out, I'm just going to think about it a bit more. ;)

I'll make another post a little later this evening.

DLF
03-13-2010, 09:44 PM
I've completed my initial design.

I'll be using 1 1/2" diameter 6061-T6 aluminum sleeves, 3.2" for the front and 3" for the rear. I'll have them Mil Spec hardcoated to protect against corrosion.

Each position will require both an upper and a lower 4" diameter UHMW bushing.

The stock steel lower mounting plates will be reused.

I'll have to buy about $200 of tooling to make these.

Material costs are estimated at $75.

I estimate that it will take me more than one, but less than two full days to make a complete set.

Bolts will not be included. My reasoning for this is that some, myself included, would be willing to pay the premium for the Ford bolts (assuming that they are still available, I'm checking that), while others would prefer a less expensive generic bolt. Also, depending upon the condition of yours, new bolts may not be required.

Initial pricing will be $400 shipped (lower 48).

I'll offer a discount of $50 for early adopters who prepay in full between now and March 31, 2010.

The first sets should be ready to ship within 3-4 weeks (turnaround time on the hardcoating is 7-10 days).

Who wants a set?

Do you plan on doing any welding to your subframe? Ive seen a few weld them up and add some support metal here and there

This is a great new product and I am very interested. However, I have other fish to fry at present. (No Lent pun intended.) If and when I get my other car issues straightened out, there is a good chance that I will purchase a set of these.

Thanks for coming out with all these parts for the club. It's great to see someone with the required capabilities take enough interest to get tthe ball rolling for everyone.

FWIW, I decided to check with ARP to see if they had any Stainless 300 bolts in this size.

The good news is that they're are starting to make 12mm bolts. :)

The bad news is that the longest they're making is 100mm. :(

Got the UHMW stock in today.

Made the prototype upper bushing and it fits just as I designed. I'm quite happy with it.

Tomorrow I'll make the prototype lower, and then start making a few sets.

Reminder: There are 6 sets in this batch and 3 are already spoken for.

DLF

Finished the lower bushing prototype today. Took a while to get the dimensions just right, but it came out great. And the bushing set w/sleeve even weighs less than the stock parts they're replacing. :cool:

Made the three remaining upper bushings for my car, and will make the three remaining lower bushings tomorrow. Then I have to wait for the sleeves to come back from anodizing (they arrived in NC today). Once, I've installed mine, and I'm satisifed that everything is as it should be, I'll produce and ship the sets that have been paid for.

I'm sending a set out Monday to someone that has a spare sub-frame, out of the car, for a test fit. If all goes as expected, the other kits that are paid for will go out within a week or so.

To install the new UHMW bushings:

1. Clean the sub-frame bushing mount holes.

2. Insert the upper bushing. You may need a dead blow hammer, it's an interference fit.

3. Tap in the sleeve from above, to just below the top surface of the upper bushing.

4. Place the 1 1/2" stainless steel washer on top of the sleeve.

5. Press the lower bushing up from below until it stops. There should be a very small gap (see picture) between the top of the lower bushing and the sub-frame, that will disappear when the bolt is tightened.

6. Insert all 8 bolts loosely, using the stock sub-frame bracket (front) and cup (rear). 4 - sub-frame, 4 sub-frame brackets

7. Align the sub-frame using the alignment holes on each side near the back of the sub-frame. (I'll post some pictures of this when I re-install mine in a couple of days)

8. Tighten bolts as indicated.

Sub-Frame alignment and installed pics.

On the left rear is a tab on the sub-frame that corresponds to a hole in the uni-body that is used to align the sub-frame during installation. Use a 3/4" OD pipe (or something similar, I made my own tool), and make sure that the pipe is vertical. Tighten the left rear mount and then go to the right rear of the sub-frame and use the alignment holes located there to complete the alignment. Then torque all four bolts.

ROAD

My car is already setup pretty stiff. H&R Springs, Koni Shocks (set + 1 1/2 turns from full soft), Delrin IRS Bushings, 1 3/8" bars F&R.

Even so, I was expecting a fairly dramatic change, and a noticeable increase in NVH. However, the change wasn't all that much. There is a slight increase in harshness over expansion joints and the like, and a little more mechanical noise, but not much. I would have no issue using these mounts on a daily driver.

I made the round trip to Englishtown (70 mile round trip) today on DR's, so I didn't push too hard in the corners, but it did feel more stable. I'll take a road trip later this week on my street tires, and push a little harder.

TRACK

On 3/10/2010 @ Englishtown, I had my best previous results. The DA that night was -912 feet.

My best ever 60' was 1.765
My best ever ET was 12.925

Today I went to Englishtown again. The DA today ranged from -685 to -558 feet.

I made no changes to my car, other than the UHMW sub-frame mounts. Same tune, gas (Exxon 93), tires (MT 275/40-17 DR's), same tire pressure (20 lbs.), and the same launch RPM (3,500).

My new best 60' is 1.742, and another 1.759
My new best ET is 12.879, two others were 12.921 and 12.913

So, in worse conditions, I picked up .023 on the 60' and bettered my previous 1/4 mile time by .046.

Most noticeable was the lack of drama during shifts. Previously, the car sort of shimmied when I shifted, today I felt none of that.

I'm quite pleased with the early results. I think with more passes I can improve even more, now that the car is planted better.

I just got home..a 99 mile trip.

Here are my thoughts.

1) The car does ride rougher. But for those who want the ultimate its a fair price to pay
2) The feel when driving is incredible. It just hugs the road. I already had the Delrin bushings but this is icing on the cake.It just feels so incredibly tight..And my subframe mounts were in great shape when taken out..So there was no issue there.

I havent gotten on it in a launch type situation but that i ssoon to come

Well, I'm not going to make any more of these until someone orders a set.

I can't afford to invest $400 + in materials and hardcoating, spend days making these, just to have them sit around. :(

So, the first person who orders a set will get them for $350 (paid via the PayPal personal tab), about three weeks after they make payment, and all others will have to pay $400.

I just installed mine (car isn't mobile though) and I had a comment/question. The suspension bushings are greased, but is there any concern about chafing on these subframe bushings? I coated mine with grease before assembling, but I'm not sure if that was the right thing to do or not.

I just installed mine (car isn't mobile though) and I had a comment/question. The suspension bushings are greased, but is there any concern about chafing on these subframe bushings? I coated mine with grease before assembling, but I'm not sure if that was the right thing to do or not.

I didn't lube mine, they're not supposed to move. Can't see how it would hurt, though.

The first person who orders a set will get them for $350 (paid via the PayPal personal tab), about three weeks after they make payment, and all others will have to pay $400.

I've received an order, so this deal is off the table.

Sets will be ready to ship in 2-3 weeks. When they're ready, I'll put up a web page for ordering.

I've made another batch of these, 1 set is sold, 4 are currently available.

If I make another batch in the future, the price will be going up to $450 as these are a complete pain to machine, so this is your last chance to get them at this price.

NOTE: These are not stock style rubber replacement mounts. They are designed for performance applications, as NVH will be adversely affected. You will feel, and likely hear, more than you would with the stock mounts.

I just want to let you all know that my subframe bushing were in perfect shape and I got these anyway because..Well what the heck. They made a huge difference in feel. Yes the car got a little stiffer but it was an amazing transformation in control and feel.

Not sure how they would be all alone but along with the delrin control arm bushings my rear end felt great. If your sitting on the fence about these get them whie you can. You never know when these things will be out of production!

Any chance you'll be creating another batch? :)

Anything's possible, but not unless I get at least two or three prepaid orders @ $425.

The investment in both time and money, which is significant, just to have 5-10 sets sitting around isn't worth it to me.

Making the spacers and then having them hardcoated will take 2-3 weeks and a couple hundred dollars. The raw UHMW is only cost effective in 6' lengths, and is also quite an investment.

I'd love to make another batch and help people out, but they don't sell quickly enough for me to take the risk without some prepaid orders. You can see above that it took over a month for the last set to sell.

Are these bushings a good answer to the major wheel hop problems that 5-speeds have? I have replaced every bushing other than diff bushings and these. I have replaced shocks with koni's and put airbags in my coils, no help at all.

My Delrin IRS Bushings will cure the wheel hop. And you should replace the diff bushings as well. These are the final step.

I surprised that there seems to be this much interest, since I had such a hard time selling the last few sets.

That being said, after one person pays, I'll begin working on the sleeves. The sleeves will take longer to make and then they have to be sent out to be anodized.

Unless you guys don't care about the sleeves being anodized, then I could cut the price down to $400.

Let me know what you think.

If you're trying to cure wheelhop, you should consider my Delrin IRS Bushing Kits, see the link under my signature.

However, with an '89, you might have the early stamped steel LCA's, which you would need to change to either the later cast iron Thunderbird LCA's or upgrade to the Mark VIII aluminum LCA's.

Thanks! I'll start working on the sleeves later in the week after I've finished the project I'm currently working on (a batch of SS strut rod sleeves). As I said before, it's going to take at least 2-3 weeks to make a batch of sleeves, and then send them out to be hardcoated. Once I've shipped the sleeves out, I'll start working on the bushings themselves, so it'll be close to a month before I'm able to ship the first kit.

If anyone else wishes to reserve a set from this batch of 5 sets:
