Frequently Asked Questions
Which replacement insert or hardware kit should I choose?
Match the selected option to the exact Per4mance brace model, bolt diameter, thread, crossmember, and missing component. Do not select by appearance alone.
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. Universal only within the exact Per4mance brace, insert size, thread, and hardware interface named by the selected variant. 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.
