Traxxas Heavy-Duty Suspension Arm

Traxxas Heavy-Duty Suspension Arm replaces fragile stock arms with a proprietary composite engineered for high loads, hard landings, and dependable flex in cold weather. If you send your rig at the skate park, run speed passes, or tackle rough trails, these arms add impact resilience while preserving suspension movement.

Installation is a straight swap that takes only minutes — no filing or modification required — and the arms work with existing Traxxas accessories. They fit the rear position on 2WD models and the front and rear positions on 4X4 models. The parts are offered in six color options so you can tune the look of your truck while upgrading strength.
