$300.00

Fits select 1990-2006 Eagle Talon, Mitsubishi Eclipse, Galant VR-4, Lancer Evolution, and Plymouth Laser (4G63).
The Brian Crower BC0100 Valve Spring and Titanium Retainer Kit is a critical valvetrain upgrade for the Mitsubishi 4G63 engine. Designed to withstand the rigors of high-lift camshafts and elevated RPM ranges, this kit provides the necessary spring pressure to prevent valve float and maintain valvetrain stability under boost.

- CNC machined from aerospace-grade 6AL4V titanium for maximum strength and weight savings
- High-quality single valve springs designed for durability and performance consistency
- Essential for engines utilizing aggressive aftermarket camshaft profiles
- Direct replacement for OE springs and retainers
