GPM Racing Alloy Rear Adjustable Spring Damper with Alloy Ball Top&ball Ends-1PR Set (1.3mm,1.5mm,1.7mm Coil Spring & 4mm Thick Shaft) for Traxxas 1/10 Slash 4x4 Lcg (SLA102R)

Precision rear damper for TRAXXAS SLASH 4X4 chassis

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.

What are the assembly items and rates?

One pair of alloy rear adjustable dampers with alloy ball top and ball ends, plus coil springs in 1.3mm, 1.5mm and 1.7mm rates for incremental tuning.

How does the 4mm shaft affect dynamic behaviour?

The 4mm shaft increases bending stiffness and reduces lateral flex, which helps the piston track more consistently under repeated, high-frequency impacts and improves predictability.

Recommended tuning workflow?

Begin with the mid-rate spring, set baseline preload and ride height, then evaluate rebound and droop. Move one spring rate at a time and log handling changes to build an effective setup map.
