PRW rocker arm studs are premium engine fasteners, made from strong, heat-treated 4135 chromoly steel with rolled threads. They're designed to securely hold rocker arms in place, handling the extreme forces in race and high performance engines for reliable valvetrain operation. The studs are crucial for securing the rocker arms that open and close engine valves, often paired with poly locks and used in upgraded systems for better durability and performance than stock parts. Order the set recommended for your vehicle. Additional product details: * Material: Cold-formed from 4135 chromoly alloy steel for maximum strength * Construction: Rolled threads provide superior durability and resistance to stripping * Application: Engineered for high performance and racing engines where stock studs might fail * Function: They act as threaded posts in the cylinder head, anchoring the rocker arms and associated hardware (like poly locks) * Durability: Standard components can bend or break under high spring pressures and aggressive valve lift * Reliability: PRW studs provide a secure, dependable foundation for the valvetrain in demanding conditions * Upgrades: Essential when upgrading to stronger rocker arms or higher-rate valve springs

PRW LS Series fulcrums are performance upgrade kits for GM LS engine rocker arms. They replace the stock rocker fulcrum with a stronger trunnion assembly—often featuring drawn cup bearings or silicone bronze bushings instead of the factory needle bearings—to enhance durability and handle higher lift cams and RPMs. These kits are designed to upgrade the stock LS rocker arms to make them more robust for performance applications. Key features: * The primary purpose is to improve the strength and durability of factory LS rocker arms, not to replace them entirely * Kits typically include replacement fulcrums (trunnions), circlips, and fasteners for the 16 rocker arms in a V8 engine * Kits often replace the stock's "uncaptured" needle bearings with more robust drawn cup bearings or oil-lubricated silicone bronze bushings, which are less prone to failure and collapsing * This upgrade makes the valvetrain more reliable under the stress of performance modifications like high-lift camshafts and stiffer valve springs * They provide a significant strength upgrade without the cost of purchasing a full set of high-end aftermarket rocker arms

PRW camshaft bolts are made with high precision to keep everything in place when the engine is operating at high speed. Strategically placed cam bolts will enable the cam to be attached to a vehicle's timing set and to ensure that the shaft is able to operate within close tolerances. Only the right specification of a bolt must be used, and it must be fitted correctly with the right amount of torque application, so that the amount of end play, or forward and backward movement, is kept within specific tolerances. Order the camshaft bolts for your application needs.
