HPI Savage 21 Aluminium Upper Spring Retainer - SAV13170/USP by GPM  [SAV13170/USP]

Upper spring retainer in aluminium for Savage 21

This aluminium upper spring perch is an aftermarket replacement tailored to HPI Savage 21 shock assemblies, supplied as 1pr and identified by part SAV13170/USP. It replaces the top spring seat on the shock and is aimed at suspension tuning and maintenance tasks.

The aluminium construction provides a firmer seating surface versus softer materials, helping to preserve spring alignment and consistency after multiple adjustments. It is suitable where a longer-lasting perch is required for regular setup changes.

Prior to fitting, confirm compatibility with your Savage 21 shock cap dimensions and use standard RC hand tools to remove and refit the upper shock parts. This component is intended solely for RC suspension tuning and repair.
