Product Details
Highlights
- More mid-range and top-end power for street and drag bikes. These cams work with solid or hydraulic lifters, and the idle remains unaffected up to 6,000 rpm with stock valve springs.
- Cams are computer designed and precision ground from alloy steel billets on Landis CNC cam grinders.
- Made in the USA.
- Must check coil bind, valve to valve clearance, and valve to piston clearance.
- On late '77 and later engines, the pitch diameter on the camshaft, pinion gear, and the breather valve gear was changed. These components are not interchangeable with earlier-style components unless replaced in set only. Late '77 and later gear sets are identified by a circular groove machined in the outer face of the cam gear.
- Bolt-in street cam have an "A" intake and long duration exhaust for cooler running and high end power.
- Suitable for hydraulic lifters.
