Why Settle for Less? Tech Tip 11: Shocks are such a critical key to winning performance, the technology evolvesvery fast. In just 4 years, the technology leaders have changed. The Fox/Ridetech shocks we built for years with digressive pistons, are still available, but the Fox Racing Shox are better.The JRI shock company has been sold twice in the last few years. No real performance improvement in that time. But, JRI shocks are still the best dual purpose shocks with great grip & the widest tuning range. ARS & Penske have taken the lead in development with decoupled & digressive pistons that increase grip even further over irregular surfaces on all tracks.Penske now offers their patented Regressive Valves that allow the driver to literally drive over road course curbs at speed WITHOUT unsettling the car! The highest grip, most adjustable, single adjustable is new from Fox Racing Shox. Our testing & results have shown our ARS valved canister shocks to be the absolute best on autocross courses, while our 8300DA & 876TA Penske valved shocks dominate on road courses. 42'
