At DMG Motorsports, we present the ROCKET PERFORMANCE GARAGE LLC Roller Rocker Arms for M8 models—a durable valvetrain upgrade designed to support high-lift cam applications while helping reduce wear on related components. With forged construction, roller operation, and upgraded rocker geometry, these rocker arms are built for cams with greater than .550" lift.

Features:

• Forged from 8620 steel for greater strength
• Rollers eliminate thrusting on valves to decrease valvetrain wear
• 1.640 rocker ratio suited to high-lift cams
• Bushings are 50% longer than stock, increasing time between rebuilds
• Larger thrust-surface area helps reduce wear on heads
• Oil sprays directly on the valve springs to help reduce overheating-related valve breakage potential
• Capable of .650" maximum valve lift
• Recommended for cams with .550" or greater lift
• Variant: Color m8; Size `17-24
