HPI Baja Rear Shock Tower Support, Alloy Upgrade GPM BJ030 by GPM  [BJ030]

Rear shock tower reinforcement for HPI Baja platforms

This alloy rear shock tower support serves as an aftermarket replacement for HPI Baja chassis, intended to increase stiffness at the rear shock mounting interface. By reducing flex where shocks attach, it helps the rear suspension preserve alignment under load and during heavy use.

Installation is a direct-replacement into the stock tower location using the original mounting points and hardware; confirm hole alignment prior to final torque. Because it affects local mount stiffness, expect small changes in shock response and perform damping or spring adjustments as required after fitting.

For tuning purposes, the part provides a firmer mounting surface suitable for shock relocation or multi-shock setups, helping to maintain camber and toe through suspension travel. Use the support as a chassis-stiffening upgrade to achieve more consistent rear-end behaviour rather than relying on it to change suspension geometry alone.

Select this alloy tower support when you need a more rigid rear mounting point for repeatable suspension tuning on HPI Baja models; verify fit and re-torque fasteners after initial testing.
