Show original supplier description
The Per4mance Development Billet Differential Brace is engineered to reinforce the rear differential housing for high-torque Mopar RWD applications. This brace is constructed from CNC-machined T-6061 billet aluminum, ensuring durability and strength. It is designed to attach to the differential using the main and secondary differential-case bolts, and it secures to the rear cross-member with 10 mm bolts. Key features include the use of two rubber isolators for vibration dampening and the inclusion of Grade 10.9 fasteners and P4D tool-less inserts. The brace is available in three finishes: gloss black, brake caliper red, or orange. It is designed to help prevent differential case failures, which have been reported in some high-performance V8 models. This differential brace is specifically designed for 2015–2023 Dodge Charger models (R/T, R/T Scat Pack, SRT Hellcat), 2015–2023 Dodge Challenger models (R/T, R/T Scat Pack, SRT Hellcat), and 2015–2023 Chrysler 300 models (300C and 300S). It is recommended to confirm the exact application before purchase. Installation involves attaching the brace to the differential-case and rear-cross-member points, and fasteners should be torqued to the manufacturer's specifications. It is advised to review the manufacturer's installation instructions before beginning work, and to confirm that the vehicle does not have a Borla or AFE exhaust system, as this may affect fitment or installation.
