HPI Savage 21 170mm Alloy Spring Seats - Tunable SAV13170/SC by GPM  [SAV13170/SC]

Replacement alloy spring seats for Savage 21

This kit provides a set of alloy spring seats made for HPI Savage 21 170mm shocks. It includes 4 pieces that mount at the top of the shock where the spring locates, offering a more durable contact point for setup changes.

Material and role: alloy seats are stiffer than original plastic parts, helping to preserve spring preload and reduce compression of the seat during off-road impacts.

Installation notes: install these at the shock top after disassembling the shock end. Basic tools such as a hex driver and soft-jaw vice or padded pliers are recommended to avoid surface damage; no extra fittings are provided.

Tuning context: alloy spring seats help keep springs centred, make preload adjustments repeatable and stop springs from walking during side loads or big landings. They are a straightforward upgrade for Savage 21 owners wanting a firmer spring interface without modifying springs or damper internals.
