They started by developing the solution to correct many of the problems in the front ends of McPherson strut vehicles, including the lackluster handling and performance of the factory struts, utilizing the next generation valving technology of our new Street Performance Shock line. Next they moved on to develop strut spacers, torsion bar lifting keys and other performance levelling components. And as a final touch they packaged the components up with a set of Trail Performance shocks to combine it all into one easy part number. They continue to develop new applications and add options onto existing ones.
