HPI Savage 21 Shock Rebuild Pack SAV13170A+B/AD by GPM  [SAV13170A+B/AD]

Savage 21 internal shock parts

This aftermarket package supplies internal damper components made for HPI Savage 21 units that use SAV13170A and SAV13170B assemblies. The items act as service replacements to let you rebuild shocks and carry out basic setup tuning.

Only the SAV13170A and SAV13170B configurations are supported, so check your truck parts list before ordering. Fitting generally requires stripping the damper, checking pistons and seals for wear, then reassembling with the correct shock fluid and spring preload to achieve the desired response.

Ideal for maintenance days or when you want to fine tune shock response during test runs; this kit covers routine servicing and gradual tuning of Savage 21 shocks.
