If you already have our original style of BDX 36" front end kit, with the new upper A arms and mounts, then you can upgrade to the HY-PRO version. The HY-PRO spindles are 1.25 inches taller below the lower ball joint, which provides more clearance for the lower A arms. Less chance of hitting a rock or stump with the lower A arms.
