If you're rebuilding the top end of your engine for higher RPMs or more aggressive camshafts, you'll need a valve spring that can keep up. These dual valve springs from Supertech are built to handle the increased demands of performance applications. They offer a rate of 13.2 lbs/mm, which is designed to control valve float at higher engine speeds.

This set includes 16 springs, enough for a typical 4-cylinder engine. The dual spring design provides better stability and control over the valve train, especially when you're pushing the engine hard. They are well-built to withstand the repetitive stress of opening and closing valves under demanding conditions, helping to ensure reliable performance when you need it most.
