TRAXXAS 1/10 T-Maxx Alloy Lower Spring Retainer by GPM TMX13100/LSR  [TMX13100/LSR]

Alloy lower spring retainer for T-Maxx

This is an RC-scale alloy lower spring retainer produced for TRAXXAS 1/10 T-Maxx platforms, supplied under GPM TMX13100/LSR. It serves as a replacement option to locate and retain the lower end of the coil spring on T-Maxx style shock assemblies, offering a metal alternative to the original material included with some kits or hop-ups.

Installation is straightforward for users familiar with T-Maxx shock servicing: the part mounts at the lower spring seat where it interfaces with the shock body or shock cup. When removing the spring, retainers are positioned on the lower end to keep the spring concentric and to maintain preload settings during reassembly. Inspect mating surfaces for wear and confirm seating before final tightening.

From a tuning perspective, a metal lower retainer provides a stable anchor for spring preload and repeatable spring height adjustments, which helps when swapping spring rates or testing incremental preload changes. Routine maintenance should include checking for burrs or deformation after heavy use and re-seating the retainer if any play is detected.
