TECH UPDATE! - Torque Specs

The purpose of this update is to provide torque spec information for the differential main case bolts for our current brace line-up.

The main case bolts are to be torqued to a minimum of 80 ft./# and up to up to 90 ft./#'s if desired. Due to variances in design and strength of crows-foot socket heads, achieving 80 ft./#'s is not always attainable without the socket head flexing off the bolt head. In those instances, torque to 50 ft./#'s and then switch to a high quality open end wrench (extended if possible) and rotate the bolt another 100-120 degrees to attain a torque spec of 80-90 ft./#'s.

We are asked frequently about a torque spec for the cross-member bolts and there is not one. Tighten those bolts until there is a consistent squeeze (1mm bulge) across the rubber isolator. After initial installation, check tightness after 100 miles and regularly after that based on the level of track/roll/drag racing you participate in. It is not uncommon for the differential to "settle" in and require fine-tune tightening of the cross-member bolts.

Use of an aftermarket brace will impact the manufacturer's warranty on the differential. Purchaser assumes all responsibility for installation and use.

    Easy Install and Noticeable Difference

    Posted by Steven Kenniff on Dec 25th 2018

    Other than trying to fit the nuts for the top bolts into holes as small as my pinky and trying to line those up, everything else was an easy install.

    First test drive felt immediately stiffer, but you quickly get used to the feel. Like the car should have come this way stock.
