S&S CYCLE 635 H.O. Easy Start Camshaft Kit (Gear) Start smart, then hit hard. The S&S CYCLE 635 H.O. Easy Start Camshaft Kit is engineered for modified Twin Cam and Dyna applications to deliver easier starting with full-power operation once RPM comes up. How Easy Start Works The Easy Start design initially reduces crank compression for easier ignition. As the engine starts and RPM increases, the compression release lobe is centrifugally retracted , restoring full compression and running normally with no loss in performance . Key Features High lift (635 H.O.) for modified engines (106" or greater) with compression ratios between 10.0:1 and 11.0:1 Power band optimized for 3000–6000 rpm (street riding) Gear drive camshaft set for reliable timing control Includes camshafts, 4-gear set , gearcover gasket, bearings, retaining ring, o-ring, thread lock, and instructions Made in the USA Not bolt-in—requires setup, tuning, and clearance checks Fitment & Important Notes Application: Twin Cam ‘07–‘17 and Dyna ‘06 Not for models with OEM compression releases Works well with stock, un-ported heads, but S&S CNC ported heads recommended High-lift valve springs , adjustable pushrods , and clearance verification are required Gear drives may produce increased valve train noise Specifications (Highlights) Grind: 635 H.O. Intake Lift at TDC: 0.115" | Intake Lift: 0.635" Exhaust Lift at TDC: 0.284" | Exhaust Lift: 0.635" Intake Duration: 243° | Exhaust Duration: 276° Intake Lobe Centerline: 102° | Exhaust Lobe Centerline: 100.5° Product Type: Camshaft Kit (Gear) | Weight: 5 lbs | Dimensions: 11.56" x 8.95" x 4.52"
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
High lift camshaft for modified engines with 106" or greater displacement and compression ratios between 10.0:1 and 11.0:1
Best power from 3000 rpm - 6000 rpm
Includes camshafts, 4-gear set, gearcover gasket, bearings, retaining ring, o-ring, threat lock and instructions
Made in the USA
Not bolt-in.
Not for models with OEM compression releases.
Works well with stock, un-ported heads, but S&S CNC ported heads are recommended.
High-lift valve springs, adjustable pushrods, and clearance checks are required.
Due to the inherent characterics of gear drives, there may be more valve train noise.
