Precision upper spring perch for Savage 21 shocks

This is a precision aluminium upper spring perch manufactured as an aftermarket upgrade for HPI Savage 21 shock assemblies, supplied as 1pr and identified by SAV13170/USP. It replaces the original upper spring seating and is intended for suspension tuning, maintenance and improved repeatability in setup.

The alloy construction provides a stable spring seat that resists deformation under repeated adjustments, helping to maintain spring alignment and consistent performance. Use this perch when enhanced durability and reliable spring positioning are required during regular servicing.

Installation is straightforward for experienced hobbyists: verify the part against your shock cap geometry, then fit using standard RC hand tools. This component is provided strictly for RC suspension tuning and repair applications.

How do I confirm fitment before purchase?

Measure the upper shock cap diameter and compare it to the perch bore; consult your shock assembly drawing or measure the existing part to ensure dimensional match with SAV13170/USP.

Any recommended installation steps?

Remove the shock top, replace the upper spring perch, check spring centring, then cycle the shock to verify free movement and correct alignment before final assembly.

Is this suitable for frequent setup changes?

Yes, the alloy perch is intended to withstand regular setup adjustments and offers improved wear resistance compared to softer seating materials when used in Savage 21 suspensions.
