When you're building a high-performance 4G63 or 4G63T engine for your DSM, getting the valvetrain right is crucial. This Manley Performance Valve Spring and Retainer Kit is designed to handle the demands of aggressive aftermarket camshafts and extreme RPMs, ensuring your engine performs reliably when you push it hard. You'll receive matched valve springs and heat-treated aerospace-grade titanium retainers, all CNC machined to precise specifications for consistent operation.

These chrome-silicon alloy springs offer excellent fatigue resistance and high tensile strength, which translates to stable valve control even at speeds up to 10,000 RPM. The kit is specifically designed to work with aftermarket camshafts, taking the guesswork out of selecting compatible valvetrain components. While this kit includes springs and retainers, please note that valve locks are not included, so you'll need to source those separately.

This kit is a solid choice for anyone rebuilding or upgrading the DOHC 16-valve engine in their 1990-1999 Mitsubishi Eclipse, Eagle Talon, or Plymouth Laser. The titanium retainers are notably lightweight, which helps reduce valvetrain mass and allows for higher engine speeds.
