They deliver strong low-end torque and power you can really feel.
Maximum performance from 1500 to 5000 rpm when used on Dyna and Softail models.
Starts any engine regardless of displacement or compression ratio with a stock starter
Save your starter and battery; tested for 10,000 starts without battery failure
Allows for quick starting by initially reducing compression, but once the engine starts and the rpm increases, the decompression point is centrifugally retracted and the engine runs normally, at full compression, and without losses
All chain-driven cams include an installation kit
All gear-driven cams include a set of 4 gears and an installation kit
Fits 88/95/96/103 cubic inch engines
Compression ratios less than 10:1
Made in the U.S.A.
Installer should check spring coil compression, valve-to-valve clearance, and valve-to-piston clearance.
Given the inherent characteristics of gear-driven valvetrains, increased valvetrain noise may be encountered.
Not suitable for models with OEM decompression systems.
