HPI Savage 21 Alloy Upper Spring Perch - SAV13170/USP by GPM  [SAV13170/USP]

Aluminium upper spring perch for HPI Savage 21

This alloy upper spring perch is a direct aftermarket replacement designed for the HPI Savage 21, supplied as 1pr and matching part number SAV13170/USP. It replaces the upper spring seating on the shock assembly and is aimed at suspension tuning and routine maintenance on Savage 21 trucks.

The aluminium body gives a firmer spring seat compared with softer materials, helping maintain consistent spring alignment under repeated setup changes. Use it when you need a durable perch to resist wear from frequent adjustments.

Installation and fitment assume basic RC know-how: confirm the perch matches your Savage 21 shock geometry before fitting and use common hand tools to remove and refit the upper shock components. This item is intended for RC suspension tuning and repair only.
