Camshaft - Easy Start - 640 Gear Drive - Twin Cam '99-'06 (except '06 Dyna)

Highlights

• Allows for easy start by initially reducing crank compression, but once the engine starts and rpm increases, the compression release lobe is centrifugally retracted and the engine runs normally, with full compression, and without any loss in performance
• Intended for 95"/96"/103" and 110" engines with compression ratios between 10.5:1 and 11.5:1; strongest 3000 rpm - 6000 rpm range
• Made in the USA
• Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.
• Not for models with OEM compression releases.
• High-lift springs and adjustable pushrods required.

Notes

• Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.
• Not for models with OEM compression releases.
• High-lift springs and adjustable pushrods required.
• Includes 4-gear set.
• Due to the inherent characterics of gear drives, there may be more valve train noise.
