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

Lower shock spring retainer for Savage 21

This aftermarket lower spring retainer is a metal replacement designed for HPI Savage 21 scale trucks and is supplied as a pair. It locates and retains the lower end of the suspension spring on the shock assembly to keep spring position stable during setup and running.

Produced as an aluminium alloy alternative, the retainer is intended to be more dimensionally stable than plastic when adjusting preload or swapping spring rates. It suits Savage 21 chassis that use the standard lower retainer profile; always verify fit against your shock housings before installing.

Fitting guidance: place the retainers with the spring seat inward toward the shock, secure any existing fasteners according to the shock instructions, and confirm full spring travel after fitting. The part does not include additional hardware unless the seller states otherwise.
