SIngle valve spring with 65 seat pounds, 130 pounds @ .500 max lift. For use with 33-28.5 stainless steel valves up to 7500 rpm or titanium 1.450-1.200 9500+ rpm. Springs are sold in sets of 4.

NOTE*** never use performance valve springs with stock valves. Stock valve failure is common. Always run a clearance of .060’’ between max lift and coil bind. Never use aluminum retainers, the aluminum retainers wear, create aluminum dust in the engine and in some cases the locks can pull through the retainer and drop a valve. This results in catastrophic failure of the engine. Especially for a high hour boat engine you want piece of mind.
