HPI Baja Rear Lower Arm - Alloy Stiffener BJ056 by GPM  [BJ056]

Alloy rear lower arm for HPI Baja setups

This aluminium lower arm is made as a replacement part to restore accurate rear suspension geometry on HPI Baja buggies. It focuses on providing a firmer mounting point where plastic parts may have introduced unwanted flex.

The arm is intended to swap in for a damaged OEM plastic arm and to provide a reliable platform for the hub and linkage. It is supplied as a single piece and should be used with the stock HPI Baja rear suspension assembly and hardware.

Fitment notes: check hinge pin fit and ball stud clearance before tightening, and use thread-lock on metal fasteners as appropriate. Cycle the suspension through travel during installation to ensure free movement. Remember that a firmer lower arm can affect rear-end behavior and should be considered alongside spring and damper setup.

A practical metal replacement for HPI Baja owners wanting a more rigid rear link without changing factory mount positions.
