The 509 Touring Cam is designed as a bolt-in, high torque cam for 1999-’06 models, except 2006 HD® Dyna®. 180 psi cranking compression, no need for compression releases. For 88 CID engines with stock compression ratio. Idle-4500 rpm.

 Can be used with stock valve springs.

 

With the current popularity of baggers, it’s no surprise that the S&S 551 cams for Harley-Davidson® touring bikes have become a favorite with late model bagger riders. The only problem is that, due to the .550" lift, the 551 cams can’t be installed in early (1999-’04) Twin Cam 88® engines without also installing a set of high lift valve springs. That means that the heads would have to come off just to install a cam. That’s a lot of work and added expense!

 

Based on the success of the 551 cams, S&S has come up with new 509 bolt-in torque cams that work with stock valve springs in 1999-’04 engines. Like the S&S 551 cams, the new 509 cams are great for low and  midrange torque, but the 509 cam’s lower lift allows them to be bolted into stock 1999-’04 engines with stock valve springs. That saves a lot of time and money on the installation, which makes the S&S 509 a lot  more attractive to owners of older Twin Cam 88 powered bikes. Of course, the 509 cam also works great in 2005-’06 88" engines, except 2006 HD® Dyna® models. Available in chain drive and gear drive versions.

If OES, 509 or 510C cams are used with the stock chain drive system in Twin Cam 88® engines, it is recommended to use cylinder heads with stock valve springs or performance valve springs with no more than 160 lb. of seat force. For more demanding applications, we recommend the S&S gear drive cams. When using 1999-'06 chain drive cams for lifts over .510", S&S strongly recommends that the stock chain drive be upgraded to the S&S gear drive or to the H-D® #25284-08 or #25284-11 hybrid plate. This kit updates the problematic spring loaded chain tensioners to reliable hydraulic tensioners and also upgrades the oil pump. 551 cams are not recommended with compression ratio of 10:1 or higher. S&S can do a special order cam. Contact your S&S Customer Service Representative for more information. Not legal for sale or use on CA or EPA pollution controlled motorcycles.
