Another advantage of these rocker arms is their adjustability. Each arm features a conveniently located adjustment screw, allowing for easy adjustment of the valvetrain clearance. This adjustability can be especially useful in high-performance applications, where optimal valvetrain clearance is essential for maximum engine performance and reliability.

The Harland Sharp SLT18A rocker arms are also designed to work seamlessly with aftermarket camshafts and other performance upgrades. The arms are compatible with a wide range of aftermarket camshafts, making them a versatile choice for those looking to build a high-performance engine.
