TRAXXAS TRX-4 Chassis Brace, Aluminum Stiffener JR-TRX401-BK by Jazrider  [JR-TRX401-BK]

Heavy-Duty Crossmember for TRX-4 Frames

This replacement aluminum crossmember is produced as an RC-scale upgrade for TRAXXAS TRX-4 trail and scale crawlers. It replaces more flexible components with a rigid metal option to reduce chassis twist under load.

Fitting is straightforward using the vehicle's existing holes: remove the original part, position the aluminium crossmember, and fasten with the correct hardware while checking alignment with axles and body mounts.

From a setup perspective, installing a metal crossmember alters chassis flex characteristics and load transfer; you may need to recheck ride height and suspension droop after installation to retain handling balance.
