Frequently Asked Questions

Will this billet rear differential brace kit fit my 2015-2023 Chrysler 300?
That year, make, and model range is listed, but the vehicle must also match this requirement: V8 rear-wheel-drive applications. Check every additional application note before ordering.

Will this change drivetrain noise or vibration?
A properly installed brace is designed to support the differential while retaining controlled movement where the kit uses an OEM-style or rubber bushing. Existing mount wear, incorrect torque, interference, or a mismatched application can still cause noise or vibration.

Does installation require drilling or exhaust removal?
Requirements depend on the exact brace and vehicle. Rear position. Not compatible with Borla or aFe exhaust systems. Choose DIRS-R or the Standard Billet Brace for those exhaust layouts. Review the current manufacturer instructions before disassembly and verify all clearances after installation.

Installation Instructions

Use the current Per4mance Development instructions for the selected part number. Support the vehicle safely, verify the differential, crossmember, bushing, thread, exhaust, and mounting configuration, replace required one-time-use hardware, apply thread treatment only where specified, torque every fastener to the published value, and check service access and clearance before road testing.
