These GPM aluminium rear L-shape piggy back dampers are precision engineered to improve suspension reliability and tunability on the Traxxas Unlimited Desert Racer. Constructed from 6061 T6 alloy, the design emphasises rigidity, reduced wear, and stable damping characteristics under aggressive use. Reinforced damper shafts and thicker coil springs increase component life and provide a firmer working range for tuning setups.
