Upgrade or restore your desert truck with genuine Traxxas GTR 139mm Rear Shock Springs.

Rugged Off-Road Suspension UpgradeProgressive shock springs built for extreme desert action
Engineered specifically for high-speed desert pounding, the Traxxas GTR 139mm Rear Shock Springs provide the perfect balance between scale realism and intense impact absorption. The custom progressive-wound coil allows your RC car suspension to feel plush over small ripples, then rapidly stiffens as the shock compresses to prevent harsh chassis bottoming during massive scale jumps.
Finished in a resilient blue coating with a white stripe indicator for easy spring rate identification (1.042-rate), these replacement springs help tailor your brushless motor powered desert truck to match custom vehicle weights and track conditions.
