COMP Cams Rocker CS 1.65 3/8in Ultra Pro

COMP Cams is well-known for performance valvetrain components, and their Ultra Pro Magnum XD rocker arms are a solid choice for anyone looking to improve their engine's performance. These stud-mount rockers are built from durable 8650 steel, a material that holds up well over time and under stress. They feature a unique machined billet pushrod seat insert, which adds a notable layer of durability right where it counts.

What sets these apart is the attention to detail in their construction. They use precision-sorted needle bearings and hardened roller tips. This setup helps to better distribute the load across the valvetrain and reduces wear, leading to a longer service life for your engine components. They are also designed to work with most common spring and retainer diameters, making them adaptable to many builds. These rockers are fully rebuildable, which is a nice touch for long-term maintenance.

This particular set, the 1803-1, features a 1.65 ratio and is designed for use with 3/8-inch studs on a variety of Chevrolet and Buick V6 and Small Block V8 engines, including popular models like the Chevrolet Camaro, Corvette, and Buick Regal. They can handle spring pressures up to 1,000 lbs, making them suitable for many performance applications.
