These top mounts were developed with their sister company, DMS North America to fill a void in the current marketplace for a competitive, durable suspension mount that can be used in any condition and can be adjusted in a matter of seconds. They have developed these mounts for competition use, so it can be assured that no daily driven street car will ever exploit the limits of this part, and they even offer a lifetime warranty to the original owner (excluding normal wear and tear on the bearing). They are so confident in this product that the warranty even covers competition use.
Their complete line of top mounts, when possible use a unique locking mechanism that allows quick and easy adjustments that locks in place with one bolt. No longer do parts need to be clamped together. No longer is there a possibility of a creeping adjustment. The setting is precise and repeatable while minimizing any failure, deformation or deflection of the mount. If you add one position (hole) of adjustment on one side, this is the same is for the opposite side. No guessing or lining up lines. Count the holes and the settings will be equal. With this concept, it is much less likely that the customer will have a situation with stripped threads, or used reference points that are no longer legible.
All parts 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 adjustment bolts seizing and jamming on the burrs is significantly reduced.
These will fit the OEM front struts/shocks as well as any coilover that utilizes a M12x1.25 thread pitch for the top hat bolt. They will even work on shock assemblies that have an external reservoir.
