Coilovers should be rebuilt about every 20K miles. We can rebuild them using our high performance shock fluid, oil seals, bushings, .... and revalve them to perform much better in most cases. After a review of component failures, shock dyno testing, and even real time testing on our race and street cars, we have come up with services that improve the reliability and performance of most coilover systems.
