Well I was about to make a purchase on a set of 3.73 gears through a local company. And on there website they have all hte gear levels listed and at the bottom there is a "shim kit" available for 99 dollars. I called and they informed me it comes with the shims, 2 pinion bearings(??), grease and maybe a fourth item but I have drawn a blank. I asked them if it was necessay for the installation of the 3.73 gears and he said sometimes it is and sometimes it isn't depending on the condition of my current bearings and rear-end. Basically my question is it necessary? What is the typical shape of a rear-end with 132k. Can I get buy without this kit? It seems no one usually mentions it when I see someone installing gears.
Any info you can provide would be helpful!! Thanks.
