Traxxas Revo Rear Rocker Arm 90T - RE-012/S by 3Racing  [RE-012/S]

Technical overview of the Revo rear rocker

The RE-012/S rear rocker arm is engineered for Traxxas Revo platforms and is produced to replace worn factory rockers while preserving link geometry. The component supports setup changes and shock leverage adjustments without requiring modifications to adjacent suspension links.

The 90T designation denotes the specific tooth profile used in the Revo rear suspension, and the silver finish identifies the external appearance for matching and inspection. Replace the original rocker in cases of wear, bending, or when altering lever ratios to refine handling.

Installation follows standard Revo service practices: remove the existing rocker, transfer bearings or pins if serviceable, and secure the replacement using recommended torque values and threadlocker where applicable. Post-fit verification should include hinge pin alignment checks and suspension droop measurement to ensure correct geometry and predictable handling.

Use RE-012/S when restoring rear suspension geometry or when tuning leverage on Revo chassis; perform routine post-install checks to validate alignment and performance.
