BTR’s Max Pressure Spring Kit applies what we learned when designing the Platinum Spring Kit (SK001) and applies it to applications utilizing roller rockers. Due to the additional weight of roller rockers, a higher spring rate is needed to retain valvetrain stability. Whether you’re putting together a daily driver with a mild cam, a 600 hp N/A stroker, or a turbocharged 1000 hp brawler, our Platinum Spring Kit will make sure your valves are right where your cam wants them to be at all times.
