This aluminium rear lower arm is intended as a direct replacement to restore rear suspension geometry on HPI Baja buggies while adding stiffness to the lower control link. It aims to reduce flex that can develop in plastic arms over time.
The arm is supplied individually and is designed to work with stock HPI Baja rear hubs and linkages. It should be fitted using the existing hinge pins and ball studs once those parts have been inspected for wear.
Fitment checklist: confirm hinge pin and mount alignment, apply thread-lock to metal threads where appropriate, and check the full suspension travel after installation to ensure there is no binding. Upgrading to a firmer lower arm may change the rear handling balance so adjust shock and anti-roll settings as required.
A reliable metal replacement for those wanting to repair or stiffen the rear lower link without altering factory mounting points.
