3Racing Traxxas Revo Rear Rocker Arm 90T RE-012/B - RC Spare Part  [RE-012/B]

Rear rocker assembly for Revo

This rear rocker arm is supplied as a pair for Traxxas Revo models in blue, designated the 90T variant RE-012/B and intended as a direct replacement for the rear rocker linkage on Revo chassis.

In service the rocker links the hub and axle to the rear suspension linkage, affecting suspension travel and roll characteristics. Fitters should reuse the vehicle's existing mounting hardware and confirm linkage alignment during installation. No changes to motor, ESC, or driveline components are required for a straightforward replacement.

For tuning the arm uses the standard Revo mounting points, so swaps are commonly used to alter rear leverage, replace damaged pieces after impacts, or build matched sets for race prep. The blue finish helps with quick identification during maintenance and setup.
