HPI Savage 21 1.6mm Coil Spring Front for 115mm Long Damper by GPM SAV13170/SP  [SAV13170/SP]

Front coil spring for Savage 21

This is an RC-scale front coil spring produced for HPI Savage 21 setups, specified with a 1.6mm wire diameter and intended for use with 115mm long dampers. The part is supplied as the item listed by the manufacturer and is intended for shock replacement or spring swap during suspension tuning on Savage 21 vehicles.

Installation is a standard shock service procedure: remove the shock assembly from the chassis, disassemble the shock cap and shaft, slide out the old spring, fit the new coil spring onto the shock body or spring perch, then reassemble and check travel and preload. Adjust ride height and damping settings on the vehicle after fitting to confirm behaviour matches the tuning goals.

In tuning terms, this coil spring provides a defined spring rate associated with its 1.6mm wire diameter and length compatible with 115mm long dampers, making it suitable for hobbyists adjusting front-end support and handling balance on HPI Savage 21 models.
