Engine Valvetrain

The Trust Greddy rocker arm stopper is the part which holds the lash adjuster side of Rocker arm with fixed clearance.

Trust Grex valve springs are SWCO-V silicon chrome reinforced to withstand the high speed revolution encounter in the rotating cam shafts.

The HKS head systems, including valve springs, solid lifters and seals for the Nissan SR20DET engine enabling the engine to rev up to 9000RPM safely.

The HKS valve guides are manufactured out of phosphorus bronze for superior thermal conductivity and strength at high temperatures.

HKS valve springs are designed for use with HKS camshafts for high revving engines reducing valve-float and providing greater durability.

The HKS valve stem seals ensure oil does not fall as experience with the HKS Drag GTR.

JUN racing valve springs increase durability and does not have degradation during high rotation.

The Jun strengthened valve guides prevent damage to the valve guides when used under high heat and mechanical load in highly tuned high RPM engines.

JUN titanium valve retainers has been developed for both strength and light weight for improved reliability at high RPM

Monster have designed the Reinforced Valve Spring for improved surging and for easy installation, with the spring rate of 29.20N/mm.

The Spoon polished valve set enables improved engine performance through the reduction of weight and the smooth finish enabling improved flow.

The Spoon valve spring set improves spring strength and ability to produce high revolutions and thus higher performance.

The Toda Rocker Arm Plugs and Spacers are combined with the VTEC Killer Camshafts to offer race level performance and reliablity.

The Toda spool Valve Cover is combined with the VTEC Killer Camshafts from Toda to offer race engine performance.

Toda valve guides have been developed from racing experience and development by Toda to ensure the highest quality and most durable valve guides.

The Toda valve springs have been especially designed to enable increased lift with reduced weight for high performance modified engines.

. Copper has one of the highest thermal conductivities

The Tomei Oversize Valves

The Tomei rocker arm stopper is the part which holds the lash adjuster side of rocker arm with fixed clearance,

Tomei have adopted a solid pivot system to enable cam clearance adjustment, while keeping the total height of pivot of each cylinder fixed.
