PRW Pro Series stainless steel rocker arms are manufactured from lightweight, premium quality 17-4ph stainless steel—a superior alloy high in nickel and chromium. This rigid, premium material provides outstanding fatigue resistance, and high-yield strength to help resist deflection. These rocker arms feature full-cage, friction-reducing needle bearings, and extra-large trunnions to spread out the load and reduce wear. Each rocker body is hand-polished, assembled, and carefully inspected to deliver the finest quality available to the racing and performance industry. Reduce your valvetrain mass with durable, lightweight PRW Pro Series stainless steel rocker arms. Order the set recommended for your specific vehicle and engine size. Features, items, and specs: * Wide assortment of ratios to suit almost any cam profile * Each set of 16 comes complete with PRW RockerLocs * Stud-mount design provides plenty of clearance for large diameter springs * CNC-machined pushrod cups * Heat-treated steel nose rollers and shafts resist severity of racing and minimize scrubbing

Skunk2's industry-leading Alpha Series titanium valve spring retainers are designed to significantly reduce valvetrain mass, resulting in more horsepower and improved valvetrain stability. They feature radius-cut edges for additional rocker arm clearance and reduced weight, strategically positioned lightening grooves, and reduced overall heights for better valve seal clearance and even further weight reduction. These components are manufactured using the latest 3D CAD (Computer Aided Design) and FEA (Finite Element Analysis) to ensure that each retainer is optimized for strength, as well as for reduced weight. Skunk2 engineers then test and prove their designs on the engine dyno, as well as the race track. Once approved for manufacturing, only medical-grade titanium that's been ultrasonically inspected and certified is used. Following CNC machining, each retainer is then individually inspected to ensure proper hole diameter, taper, and that each are free from machining defects to ensure proper installed valve spring heights and pressures. Each retainer is serialized for your protection, including valuable information, like material batch specifics, as well as production and inspection dates.

PAC Racing 600 Series valve spring retainers are the latest developments from PAC Racing Springs. These retainers feature ultra-lightweight designs from proprietary valve spring-type alloys. PAC Racing's sophisticated processing, such as micro-polishing and Nano Peen technology, are used to enhance retainer life. The high hardness of the steel provides higher wear resistance properties to offer superior abrasion resistance and improved fatigue strength, while also reducing weight. PAC Racing 600 Series valve spring come with a reduced step and need to be combined with a matching seat (where applicable) to optimize the performance of the valvetrain.

PRW Power Plus Nitro-Carb steel stud mount rocker arms help flex associated with OEM or aftermarket stamped rocker arms at high rpm. Gas nitride is a process is used to increase surface hardness significantly. When combined with high-grade steel rocker bodies, the result is improved durability, better lubrication and less wear on rocker arms and pushrods. The added benefit is a dramatic increase in the stability of the rocker arm when used with higher valve spring pressures. These Nitro-Carb rocker arms are an excellent choice for circle track racers looking for the extra performance "edge" when used in conjunction with other component parts. The rocker arms are designed with a long slot for 3/4 race and mild performance camshafts. OEM design elements with standard rocker arm pad meet most circle-track sanctioning body rules and regulations. Order the rocker arms for your application needs. Benefits/Characteristics: * Nitro-Carb rocker arms specifically designed for higher spring pressures and hardened pushrods * Racing or performance replacement rockers for engine rebuilds with stock or PowerPlus+ Cams * Reduced noise and slop the flex associated with worn or lesser quality stock rocker arms * Adjusting nuts and pivot balls are included where required for installation * Long slot for 3/4 race and mild performance camshaft compatibility
