Anyone who has or anyone going to install the BHJ balancer on their SC you need to be made aware of a problem when using the stock damper to crank bolt. Even the Mustang 3.8L bolt. The BHJ snout is 1/2" thicker than the factory one. The problem is after installing the BHJ damper you will have less than 1/2" of threads holding the damper on to the crankshaft. Enough threads to hold the damper on but not enough to keep the threads from stripping out! You need a 55mm long 10.9 grade bolt to install the damper correctly. All the BHJ 3.8L balancers are made with the same 2.5" snout depth. If you have already installed yours and used the stock bolt replace it ASAP. Reuse the washer. Damage can and will occur to the crank and balancer. If you need help getting ahold of the correct length bolt I have them for $2 each plus shipping.
OEM 2" snouth depth.
BHJ 2.5" snout depth.
The red line shows how much of the bolt actually is threaded into the crank when using the BHJ. This bolt is the Factory length crank bolt and washer. M14 x 40mm 1.5 pitch With the washer installed it's 35mm long.
