Manley 90-06 Mitsubishi 4G63-4G63T DSM / EVO DOHC 16 Valve Spring and Retainer Kit (w/ Valve Locks)

If you're working on the valvetrain of your 1993-1997 Eagle Talon, 1995-1998 Mitsubishi Eclipse, 2003-2006 Mitsubishi Lancer, or 1990-1994 Plymouth Laser, this Manley Performance valve spring and retainer kit is designed to handle the demands of high-performance engines. This kit replaces your stock components with well-built parts that offer improved durability and stability, especially when you're pushing your engine to higher RPMs or running aggressive aftermarket camshafts.

Manley uses chrome-silicon alloy for the springs, which gives them great resistance to fatigue and high tensile strength. This means they'll maintain consistent control over your valves even at extreme engine speeds, up to 10,000 RPM. The kit also includes heat-treated, aerospace-grade titanium retainers that are CNC machined for accuracy, and the included valve locks are made from heat-treated steel. This combination is built to withstand the stresses of performance use, ensuring reliable operation.

This kit comes with matched valve springs, retainers, and the necessary valve locks to complete the job. It's a popular choice for those rebuilding or upgrading their 4G63 or 4G63T DOHC 16-valve engines.
