PRW harmonic damper bolts help hold your balancer properly locked in place as they absorb the massive energy from crankshaft flexing. Professionally designed to withstand 180,000 psi fastener yield strength, they also include a wide-area 1/4 in. thick washer to further spread the fastening load. For installation ease, these bolts feature a deep-socket, 12-point head-style so your torque wrench stays fully engaged up to spec. Show your knuckles some mercy--complete your install with PRW harmonic damper bolts. Order the bolt recommended for your specific vehicle and engine size.

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.

PRW Main Cap Side Bolts uses premium grade Custom 4135 Steel rated at "aircraft" quality. Their side bolts are then specially heat-treated to 180,000 psi. This heat-treating procedure allows for total heat penetration which results in a stronger, more superior stud compared to lesser quality studs from other manufacturers. PRW main cap side bolts are then centerless ground after being heat treated and then thread rolled which assures better fatigue strength than having this process done before heat treatment. This manufacturing process may cost more to do but the results are well worth the extra effort.

PRW Power rocker arm shaft stands are components that hold rocker arms on a central shaft instead of individual studs, providing greater rigidity and stability in high performance engines. These stands are made from strong billet 7075 aluminum and are designed to reduce flex, improve alignment, and ensure proper rocker arm function during high-RPM operation. They're crucial for high-horsepower applications, especially those involving aggressive engine builds, high-lift camshafts, and racing. Function and benefits: * Increased rigidity: The reinforced shaft-mount design eliminates the flex associated with single-stud mounts, allowing the system to handle higher loads. * Improved stability: By holding the rocker arms in a fixed, parallel position on the shaft, the stands ensure precise valve motion and consistency. * Enhanced durability: They are built for high-RPM and high-pressure applications where traditional rocker systems might fail. * Valvetrain geometry: They maintain proper rocker arm geometry and alignment, which is essential for a well-performing engine. How they are used: * Shaft-mounted system: Unlike standard rocker arms that mount on individual pushrod guide studs, shaft-mount rockers are mounted as a set onto a rigid steel shaft. * Stand components: The "stands" or "pedestals" are the parts that are bolted to the cylinder head and provide a mounting point for the shaft itself. * Installation: Proper installation is critical and involves checking the roller's sweep across the valve tip to ensure it is aligned correctly.
