S&S Gear Drive Camshaft Kit for Harley Davidson Twin Cam

S&S has long excelled in revving up the performance of Harley-Davidson motorcycles, and they're hardly newcomers when it comes to camshaft innovation. If you're looking for more power from your bike and you've already tackled the simpler bolt-on upgrades, then an S&S cam is your next logical step. Installing an S&S cam is a surefire way to get exactly what you want out of every single ride.

Kits for gear driven cams include all parts necessary to convert to gear drive for improved cam timing accuracy and eliminate the stock cam chain tensioner.

S&S Chain & Gear Drive Cam Chest Kit available here

Note: 1999–2004 stock valve springs will handle camshafts with lift up to 0.510". If a camshaft with higher lift is installed, high lift valve springs must be used.

Note: We highly recommend replacing the pushrods with S&S Quickee pushrods, it allows quicker, easier installation of the cam without the removal of the rocker covers. OEM pushrods may be cut to permit removal without rocker disassembly

Features:

Increase performance at an affordable price, reusing many stock components.
S&S gear drive camshaft kits contain front and rear cam, inner and outer gears, gear cover gasket, bearings, retaining ring, o-ring, thread lock and instructions.
Kits for gear driven cams include all parts necessary to convert to gear drive for improved cam timing accuracy and eliminate the stock cam chain tensioner
Gear-drive kits offer peace of mind – no more worries about cam chain failure
All parts in each kit are matched to ensure superior quality, fit, finish and performance
To get the best performance from a performance cam installation, a high flow intake and exhaust system is also recommended

What is Easy Start Cams?

Start any engine regardless of displacement or compression ratio with the stock starter. The most innovative S&S product since the electric compression release system, these cams will revolutionize the starting of late model big twins. These cams also install just as easily as non compression release versions and require no extra parts or machining! Available in both economical chain drive and rock-solid gear drive. Don't get caught without them!

How do Easy Start Cams Work?

The heart of the Easy Start cams is a centrifugally retracted, spring loaded, compression release lobe milled into the heel of each exhaust lobe. At cranking speeds, the lobe bumps the exhaust valve open slightly during the compression stroke, making the engine much easier to turn over. Once the engine fires and reaches 800 RPM, the lobe swings out of the tappet roller path, allowing the engine to run normally and with full compression.

Benefits of S&S Easy Start Cams:

Start any engine with a stock starter
Save your starter and battery!
Reliable – tested for 100,000 accumulative starts without breakage or compression release failure!
Automatic – no buttons to push

Note: Although several cam grinds were used in stock engines from 1999-’06, the timing specs of the 475G cams is most similar to cams used in 1999-’03 EFI engines. **551 cams are not recommended with compression ratio of 10:1 or higher.
Note: Stock valve springs in 1999-’04 big twin models can handle cams with valve lifts as high as .515". Stock valve springs in 2005-up engines can accommodate valve lifts up to .590".
