The S&S Cycle Gear Drive Cams are a gear-driven camshaft system that replaces the traditional timing chain setup. Because the gears drive the cams directly, the design eliminates timing chain lash and removes the tensioner shoes, which removes the wear points that come with a chain-driven valvetrain.

Riders choose this system for the reliability benefits. Removing chain lash and tensioner shoe wear helps the valvetrain run more consistently, and the gear drive improves valve timing accuracy. The package is a direct bolt-in upgrade for specified models and includes the complete camshaft and outer cam drive gear kits, along with a camshaft installation kit.

The S&S Cycle Gear Drive Cams weigh 0.7 lb and are sold under part number 106-5896. For riders who want a more robust valvetrain with precise, consistent timing, this gear drive system is a straightforward upgrade over chain-driven cams.

For off-road / closed-course race use only.

I am pleased with this 509C hydraulic cam plate and cam kit. I bought it to convert to a hydraulic cam tensioners, thus replacing the failing mechanical cam chain tensioners in my '03 Harley Road King (21k miles). This was my first attempt at undertaking such an effort, but it all went very smoothly. The instructions are pretty good. Couple them with the Harley service manual and the online video resources and the job will go much easier. One of the reasons I chose this kit was because S&S thought through all of the needs for the job and included everything in one easy kit, it had everything, lacked nothing. After a successful install there was a noticeable difference in the torque and power and I can ride now, rest assured, that my bike (and investment) is not in jeopardy of any component failures. I highly recommend this product.

Extremely nice kit. Takes a lot of the guesswork out of buying all these parts separately. Very nicely packaged. Parts appear to be high quality as well. I purchased this because I have a 2004 Softail Heritage with the Twin cam 88. It still had the original mechanical cam chain tensioners. At 33k miles, it was time for an upgrade. S&S makes the best aftermarket parts in the business. One thing to be noted: this kit does not include new timing chains. Everything you see in the picture is included in the kit. Also comes with quite a few various O-rings and a whole bunch of loctite (2 little tubes of red, and 3 of blue). There’s 2 pretty big, generous tubes of engine assembly lube included as well. So, depending on your build, this kit probably has most of what you need. 10/10 I’d buy it again. I hope this helps. Keep the shiny side up, and the rubber side down Riders.

Great cam that woke up my Softail Deuce which is 88 ci. Bike has power and torque at a very wide range or RPM. So happy with it.
