Couldn't get more then a year out of them before I started to float valves... and that was using a mild roller cam (well within their specs). After 2 sets (kinda hard headed) I made the switch to PAC and never looked back. They cost more, but they last a whole lot longer. No more floating valves, broken rocker arms and bend valves. Guess the PAC springs aren't that expensive after all. In short... keep looking. Good Luck

I check the seat pressure on a regular basis and I shim them as needed.If I were buying new springs I sure might look for another brand though. If using them be sure to use hardened shims under them as the dampers will saw through soft shims or aluminium heads. welcome to moparts

Typically happens in cold weather after 600 passes. Cant argue with that kind of life though. .704 lift with a 1.6 rocker and 280 @.050 AFCO, Rons Fuel Injection sponsored Dodge Challenger Mention Street Lethal Motorsports
