Swap in the JAZRIDER JR-LSRR01-S aluminium knuckle spindles to reduce flex in the front end of your Losi Super Rock Rey. These knuckles deliver more direct steering feedback and help the truck track truer across rough terrain.
Aluminium lowers the chance of cracking and maintains alignment under load, which means fewer mid-run repairs and steadier handling. The upgrade is ideal for those pushing their truck on challenging surfaces.
Installation uses the original mounting points and hardware where possible, so you can complete the changeover with standard hand tools and a short workshop session.
