This GPM aftermarket front and rear damper pair is intended as a direct replacement or performance upgrade for the HPI Savage 21. The assembly uses aluminium alloy components and includes preload collars, mounting hardware and a black dust-proof plastic sleeve to help limit grit around the piston.
Setup and tuning notes: the 170mm length is targeted at hobbyists who need consistent spring and oil response for fine tuning. These units work with the stock Savage 21 shock towers and mounting points and are handy when experimenting with different oil weights, spring rates and ride height to improve traction on uneven ground.
Installation advice: supplied as a 1pr kit with screws and alloy collars for standard Savage 21 posts. Typical hand tools, a hex driver and shock pliers will complete the swap. Check collar preload, thread pitch and stroke clearance before sealing the damper.
A practical aluminium damper upgrade for Savage 21 drivers looking for consistent damping and simple dust protection with included hardware for setup and repair.
