Harrop Engineering is proud to announce the launch of a comprehensive program involving the design and procurement of our own range of USA billet based camshafts and valve-train components.

The new camshaft range is a Harrop Engineering exclusive, utilising the experience gained during 60+ years of involvement at the leading edge of automotive performance upgrades, with grind designs specific to the LS range of engines as fitted to many VT to VF model Commodore and HSV models.

The H02 is an excellent all round grind that suits both naturally aspirated and supercharged applications, offering a nice lumpy idle without compromising driveability. The H02 is fine for supercharged applications with standard diff ratios, but if you have a naturally aspirated vehicle, you will see much improved driving performance when coupled with a higher ratio, say 3.7 or 3.9:1 in manual and 3.45:1 in automatic vehicles. Automatic vehicles with the H02 would also benefit from transmission cooler, and manual owners should consider upgrading their clutch for durability.

Vehicle Applications: Holden Commodore VT-VF models including H.S.V. variants fitted with LS series engines.

H02 Camshaft Specs: 224°/232°- 0.609”/0.610” - 114°
