Technical overview

Specifically produced for HPI Savage 21 front suspension use, this coil spring features a 1.6mm wire diameter and is intended to fit 115mm long dampers. The component is supplied as listed and is suitable for spring replacement or tuning swaps on Savage 21 vehicles.

Procedure for fitting is standard: detach the shock from the chassis, remove the cap and shaft, take out the old spring, position the new coil on the shock body or perch, then reassemble the shock and verify travel and preload settings. Adjust ride height and damping after installation to achieve the desired handling characteristics.

From a setup standpoint, the defined wire diameter and compatibility with 115mm dampers provide a repeatable spring rate useful when tuning front-end support and balance on HPI Savage 21 models.

How should I verify fitment before final assembly?

Measure the installed spring free length and confirm perch seating on a single shock before rebuilding both sides; ensure the spring seats flush against the perch and that shock travel is not restricted.

What tuning changes are typical after swapping to this spring?

Expect a change in front support and potentially ride height; common adjustments include altering preload, swapping shock oil weight, or fine tuning damping to regain desired handling balance.
