Sorry for the delay on this. This is pulled from another forum post of ours with a very similar question:
We asked JRZ engineers what they recommend for rebuild intervals for enthusiasts using their RS dampers on the street. It was clear their standards were very high, and to ensure maximum performance they erred on the side of early and consistent maintenance even when no issues are present. JRZ officially recommends rebuilding their dampers every 30,000 road miles, but we know that for many the mileage goes well beyond that depending on where an owner falls into the “early preventative maintenance” vs. “replace it when it’s failing” spectrum. Damper longevity is truly dependent on a variety of contributing factors including but not limited to vehicle use, vehicle weight, stresses caused by other aftermarket parts, road and climate conditions, and the forces experienced during those miles.
Enthusiasts enjoying their JRZ RS dampers on the street can experience broad service intervals, while hardcore racers looking for any available edge over the competition may rebuild at a much tighter service interval. Competitive racers often go as far as relying on hard data provided by shock dynos to confirm the operating condition of the dampers. Unless there is catastrophic or visual signs of failure in the form of leaks, “tired” dampers may only experience a marginal decline in operating performance.
Let us know if you have any other questions!
