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

Lower spring retainer for Savage 21

This aftermarket lower spring retainer is a metal replacement intended for use on HPI Savage 21 scale RC trucks, supplied as a single pair. It serves the specific role of seating the lower end of the suspension spring on the shock assembly to keep spring position consistent during setup and running.

Designed as an alloy part, the retainer provides a dimensional alternative to stock plastic components, useful when setting up spring preload or frequently changing spring rates. Fitment is for Savage 21 chassis layouts that use the standard lower spring retainer form factor, confirm compatibility with your shock housings before installation.

Installation notes: orient the retainers with the spring seat face inward toward the shock, secure any existing hardware per your shock’s specifications, and verify spring travel after assembly. No additional hardware or tools are included with the part unless listed by the seller.
