TRX4M 52mm CNC Aluminum Shock Bodies TRX4M052F/R by GPM  [TRX4M052F/R]

52mm CNC machined aluminum shocks for TRX4M tuning

This front and rear spring damper set is engineered for TRX4M 1/18 crawlers using machined aluminum 6061-T6 housings. Each damper is oil-filled and sealed to maintain damping consistency under trail loads, while preload is adjusted at the top spring retainer to alter initial spring compression without changing spring length.

Functionally the dampers reduce oscillation and absorb impact energy to stabilise the model on uneven surfaces. They are compatible with the front or rear damper positions on the TRX4M 1/18 kits listed below. The kit supplies shock bodies and replacement springs so installers can tune rebound and compression via oil selection and spring preload adjustments.

For technical builders seeking a durable aluminum upgrade for TRX4M 1/18 crawlers, these 52mm dampers provide predictable preload adjustment and oil tuning to refine ride dynamics. by GPM
