At the axle end they utilize an OE-style poly bushing for long service-free operation and better isolation of noise vibration and harshness (NVH). At the frame mount they feature a large forged flex end for strength durability and off-road articulation. The forged flex ends allow length adjustments to correctly position the front axle and correct caster. Capable of 15-degrees of misalignment in either direction for more flex out on the trail.
