Frequently Asked Questions
Will this rear differential brace kit fit my 2009-2014 Chrysler 300?
That year, make, and model range is listed, but the vehicle must also match this requirement: V8 RWD with the required Getrag 226 finned differential housing. 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. Do not order for a smooth differential housing or an application without the required Getrag 226 mounting geometry. 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.
