The CJM Components Pro Mod Dual Valve Spring Kit with Titanium Retainers for Subaru EJ engines is engineered with a focus on precision and durability. Each spring is wound from premium materials and undergoes advanced processing and end-coil treatments to deliver outstanding load-loss resistance and long-term endurance.
Unlike conventional one-rate spring kits, CJM Components has independently optimized the intake and exhaust springs, tailoring spring rates and seat pressures specifically for each side of the valvetrain. This targeted approach provides several key advantages:
Improved valve-seat life due to more appropriate closing forces
Reduced parasitic loss in the engine’s timing system, freeing up horsepower
Lower wear throughout the valvetrain while maintaining excellent control at high RPM
The beehive design further reduces valvetrain mass by enabling the use of lighter retainers, enhancing responsiveness and increasing RPM capability.
