TRAXXAS 1/5 X-Maxx & X-Monster 7075 Alloy Shock Cap Piggy-Back Rebound Upgrade by GPM  [GPM]

7075 alloy cap: short overview

This 7075 alloy shock cap is an RC-scale damper accessory intended for front or rear use on compatible TRAXXAS chassis. It replaces the stock cap with a lightweight, high-tensile 7075 aluminium body and an integrated seal cap designed to reduce leak paths and help keep spring preload consistent under load.

Built as an L-shape piggy-back unit with a built-in piston spring, the cap gives a simple method to influence rebound without swapping the internal piston. It is specified for use on non-oil-filled shock setups, with tuning performed by the red screw at the base of the negative pressure cylinder to vary spring stiffness and rebound feel.

Installation is straightforward for anyone familiar with factory dampers, and the part will fit original shock bodies and GPM shock bodies where compatibility is stated. The component is intended for RC models to refine handling balance, reduce friction chatter, and manage pressure during compression and rebound cycles.

As an aftermarket upgrade for compatible TRAXXAS models, this 7075 alloy shock cap is intended to deliver a durable, tunable alternative to stock caps for hobbyists concentrating on suspension balance and rebound control.
