|These are made using state of the art 5-axis CNC machining out of T6-6061 aluminum, and use graphite impregnated bushings. The bolt holes are made from a technique called "thread forming" which is much superior to the typical cutting tap that others use. It creates a smooth thread that has no sharp points which means the chance of the bolts seizing and jamming on the burrs is significantly reduced.
These will fit the OEM rear struts/shocks as well as any coilover that utilizes a M10x1.25 thread pitch for the top hat bolt. They will even work on shock assemblies that have an external reservoir.
