The Diamond Series by Harland Sharp
is the most recent addition to the
Harland Sharp family of roller rocker arms. 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 valve train.

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
