Precision steel coil and Delrin seating for Savage 21 shocks

This aftermarket spring is engineered to fit HPI Savage 21 shock assemblies and is supplied as one pair. The design uses a precision-wound steel coil combined with Delrin seating to provide consistent seating, reduced wear at contact points, and predictable mechanical response in shock rebuilds.

The component is intended strictly for RC suspension tuning and replacement of worn stock springs. It is not suitable for any full-size vehicle application and is produced for model-scale hobby use.

Service and installation follow established shock maintenance practice: disassemble the shock, replace the spring and retainers, then reassemble while checking seals and bearings. Replace any hardware that shows wear to maintain correct function and repeatable setup.

What seating material is used and why?

Delrin seats are used to stabilise the spring at the retainer, offering low friction and resistance to wear under repeated compression cycles.

Is this spring a direct dimensional match?

Yes, the spring is produced to match Savage 21 shock geometry and is supplied as 1 pr for direct replacement in the shock assembly.

Recommended inspection routine?

Inspect coils and seating surfaces during regular shock servicing and replace the spring if you observe deformation, corrosion, or excessive wear at the contact points.
