HPI Savage 21 Replacement Alloy Lower Spring Retainer SAV13170/LSR by GPM  [SAV13170/LSR]

Alloy lower spring retainer for Savage 21 setup

This aftermarket lower spring retainer is a metal replacement intended for HPI Savage 21 scale RC trucks and is supplied as a pair. It supports the lower end of the suspension spring on the shock assembly so the spring stays correctly seated during setup and use.

Manufactured as an aluminium alloy option, the retainer offers a more robust replacement to stock plastic parts and is handy when tuning preload or swapping springs frequently. Fitment is for Savage 21 chassis using the standard lower retainer geometry; confirm compatibility with your shock lower cup before fitting.

Fitment notes: position the retainers with the spring seat facing into the shock, secure any existing hardware following the shock makers guidance, and verify spring travel once installed. No extra screws or tools are included unless listed by the vendor.
