TRAXXAS TRX-4 Defender Rock Rail Plate for Scale Crawling Stainless Diamond JR-TRX434 by Jazrider  [JR-TRX434]

Scale tread plate for TRX-4 Defender rails

This is an RC-scale rock rail tread for the TRAXXAS TRX-4 Defender chassis, listed under model JR-TRX434 and supplied by Jazrider. The stainless diamond-plate finish gives a textured, anti-slip surface along side rails to aid realistic footholds during slow technical crawling.

The part is designed to attach to the TRX-4 Defender's existing rock rail mounts, adding a tread surface without altering suspension setup or drivetrain behaviour. The stainless construction emphasises wear resistance and steady contact with scale tyres and holds.

Fitting tips and tuning impact:

• Ensure the part lines up with TRX-4 Defender rock rail mountings before securing; avoid drilling or changing chassis sections unnecessarily.
• Perform a trial fit to check wheel and linkage clearance and adjust body mounts to prevent any interference.
• Use suitable fasteners and a moderate thread locker in high-vibration zones; inspect joints after the first outings.
