This GPM SLA102R rear adjustable spring damper is an RC-scale replacement part designed for TRAXXAS SLASH 4X4 chassis owners who want a compact, serviceable alloy damper for rear suspension tuning. The unit ships as a 1pr set and includes three spring rates and a thicker 4mm shaft to alter rebound and midstroke response without changing major suspension geometry.
The component includes alloy ball top and alloy ball ends and is supplied with 1.3mm, 1.5mm and 1.7mm coil springs so you can vary spring preload and effective spring rate. The 4mm thick shaft offers increased rigidity compared with thinner shafts and helps maintain alignment under load in high-frequency impacts typical of short-course RC driving.
Installation notes: the damper is intended as a direct rear shock replacement for the stated chassis; check fitment against your existing shock towers and mounting hardware. When tuning, change springs one step at a time and verify ride height and droop after each change to maintain predictable handling. This part is an RC accessory only and is not for full-size vehicle use.
Use this damper to fine-tune rear response on TRAXXAS SLASH 4X4 setups where small changes to spring rate and shaft stiffness improve handling balance and bump control.
