OEM-height linkage - maintains stock ride geometry and head angle. Quad precision bearings - 2 bearings per pivot vs 1 stock allows for more needle bearings to carry the load and allows the grease to split from the bolt and lube each side evenly. Grease-channel bolts - custom-designed bolts with integrated grease Zerks for direct lubrication to the bearings - keeping these highly stressed bearings lubed offers longer service life. 7075-T6 forged, CNC-machined - we start with a forged ingot of 7075T6 and then machine it. This offers the highest strength aluminum possible with the tightest tolerances. Maintenance design - engineered so riders can service the linkage easily, extending linkage life versus stock components. NOTE: Reuses 3 OEM nuts
