S&S Cycle 509G Gear Drive Camshaft Kit
FITS 1999-2006 (EXCEPT 2006 DYNA) BIG TWIN MODELSThe 509 Touring Cam is designed as a bolt-in, high torque cam for 1999-??06
models, except 2006 Dyna . 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, 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 Dyna models. CAM SPECS: Intake Opening (degrees): 18
