Product images may differ from actual product appearance.

By literally "cutting off" the corners we were able to eliminate over 100 grams of weight. The Diamond Series is the perfect solution for any engine builder or racer looking to build a truly lightweight, yet "Harland Sharp Dependable" high performance valvetrain. By improving upon our original series and making it even lighter, the Diamond Series is a sure fire way to increase your engines net horsepower. The eliminated weight reduces the reciprocating mass allowing for faster RPM's and a higher engine output advantage.
Other features include, full needle bearing roller fulcrum, roller tip, and consistent ratios to reduce friction, wear, and to stabilize valve timing. The unique Friction Free Design gives you average gains of 15 to 40 HP. Made In The USA!
