PRW Industries 68350715 Sportsman-Series Steel Roller Tip Rocker Arm Set Small Block Chevy 262-400 1.5 Ratio 7/16 in. Stud

The PRW Industries 68350715 is a Sportsman-Series Steel Roller Tip Rocker Arm Set designed for Chevrolet small block 262-400 engines. Built from 4340 chromoly steel, these stud-mount rocker arms offer a longer pivot slot and are significantly stronger than die-cast aluminum or stamped steel alternatives, resulting in reduced rocker arm flex under high-load conditions.

The precision roller tip design minimizes scrubbing friction between the rocker and valve stem, freeing up an additional 15 to 30 horsepower compared to stock-style rockers. The integrated Deflector Shield (oil deflector) optimizes lubrication flow, directing oil to critical contact areas including the pivot balls and roller tips to reduce heat and wear. Polished pivot balls further minimize friction and ensure consistent valve timing and extended component lifespan.

Key Features:

• Material: 4340 chromoly steel body construction
• Rocker ratio: 1.5:1
• Stud size: 7/16 in.
• Includes oil deflector shield for improved lubrication
• Polished pivot balls for reduced friction and consistent valve timing
• Precision-machined nose roller axle for smooth, low-friction operation
• Rated for up to 380 lbs. open valve spring pressure
• Suitable for mild street rebuild, off-road, circle track, and drag racing applications

This set is an excellent performance upgrade over OEM stamped steel rockers, delivering improved valvetrain efficiency and durability for both street and competition use. Note: Guide plates are required for installation.
