The GPM SLA102R rear adjustable spring damper is a CNC-friendly alloy replacement aimed at hobbyists who need a durable, serviceable rear shock for TRAXXAS SLASH 4X4 applications. Supplied as a one pair set, it includes three calibrated spring rates and a 4mm hardened shaft to refine rebound and midstroke behaviour while retaining original suspension geometry.
Components include alloy ball top fittings and alloy ball ends, with 1.3mm, 1.5mm and 1.7mm coil springs provided to permit incremental preload and rate adjustments. The 4mm diameter shaft increases torsional and bending stiffness over slimmer shafts, improving piston alignment under high-frequency impacts typical of short-course environments.
Installation and setup: designed for direct rear replacement on the specified chassis; verify shock tower spacing and mount hardware before final assembly. For structured tuning, change spring rates one step at a time, measure ride height and droop after each adjustment, and record results to build a setup chart. Regular rebuild procedures apply for seals and oil; reference GPM SLA102R spare parts for service components.
Use this unit to achieve repeatable rear damping characteristics on TRAXXAS SLASH 4X4 platforms where shaft rigidity and calibrated spring choices support consistent handling and impact control.
