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 MY2015 and newer Challengers and Chargers. 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 greatly 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 on” product (on models tested to date).
