509 Chain Drive Camshaft Kit for 1999-'06 Big Twins
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.
