PLEASE PLAN ON PICKING UP YOUR BRACE FROM THE SHOP
The Per4Mance Development modern Mopar IRS rear differential brace is designed to help prevent differential case failures that have been occurring with modified Hellcats and other modern FCA vehicles. Case failure, as opposed to gear failure, can cause additional damage to the drive shaft and other parts of the vehicle.
Through thorough testing and owner testimonials, other benefits that have been reported are a more planted feel in the rear-end, less drift,and reduced wheel hop, even with stock engines. The brace is American made. All steel, nylon and rubber components are either laser or water jet cut. It comes as a complete kit and is a “bolt in” product (on models tested to date).
Fitment: the brace fits 2015 to 2017 Dodge Challenger and Charger SRT Hellcats, SRT 392’s, Scat Pack and R/T models not 2018. The standard brace design WILL NOT FIT with certain aftermarket exhausts. If you are running Borla S-type or ATAK, or Solo exhaust, please order the Reduced Clearance Brace option. Important: starting with late MY2016 vehicles, the rear IRS cross-member has holes where the brace bolts to however, there are no threaded sections. Each kit now contains two self-locking M8-1.25 nuts that will need to be physically placed in the IRS cross-member. The installation instructions detail this added step.
Reduced Clearance Brace Option is a smaller more compact design giving the clearance needed for Borla, Solo and similar exhaust systems.
