S&S Cycle 509G Gear Drive Camshaft Kit
1999-2006 (EXCEPT 2006 DYNA) BIG TWIN MODELS
The 509 Touring Cam is designed as a bolt-in, high torque cam for 1999-â06 models, except 2006 DynaÂ®. 180 psi cranking compression, no need for compression releases. For 88 CID engines with stock compression ratio. Idle-4500 rpm.
With the current popularity of baggers, itâs no surprise that the S&S 551 cams for Harley-DavidsonÂ® touring bikes have become a favorite with late model bagger riders. The only problem is that, due to the .550" lift, the 551 cams canât be installed in early (1999-â04) Twin Cam 88Â® 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. Thatâs 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-â04 engines. Like the S&S 551 cams, the new 509 cams are great for low and midrange torque, but the 509 camâs lower lift allows them to be bolted into stock 1999-â04 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-â06 88" engines, except 2006 DynaÂ® models.
