Upgrade the rear end of your HPI Baja with the GPM BJ022 aluminum knuckle arm to add durability and finer steering response. This part suits drivers who need a tougher link between suspension and wheel.
Constructed from quality aluminum, the GPM rear knuckle arm resists impacts and maintains alignment under load, helping the HPI Baja track truer and steer more predictably across rough ground.
The unit is engineered for the HPI Baja lineup for straightforward fitment. You can replace the stock piece quickly and get back to running with minimal downtime.
