This aluminum oil damper set is intended as a replacement assembly for HPI Bullet chassis, supplying the parts needed when servicing or tuning suspension on Bullet 3.0 MT and ST nitro trucks. The components are finished in orange alloy and are offered as replacement hardware rather than a pure performance upgrade.
Installation follows standard damper procedures: remove wheel hubs and original shocks, transfer internal parts such as pistons and springs if necessary, and refit using the vehicle's mounting hardware. Choose appropriate shock oil grades for tuning and confirm travel and rebound settings before extended use.
Maintenance recommendations include inspecting seals and piston surfaces for scoring, replacing torn seals, and keeping threads and shafts clean to avoid premature wear. This product is intended for RC suspension maintenance and tuning.
Use these alloy dampers to replace worn shocks or to provide a consistent baseline for suspension tuning on compatible Bullet models; verify fitment on your chassis before installation.
