Product Details

The 509 Touring Cam is designed as a bolt-in, high torque cam. 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.

It's no surprise that the S&S 551 cams for Harley-Davidson bikes have become a favorite with late model riders. The only problem is that, due to the .550" lift, the 551 cams can't be installed in 1999-2004 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 509 bolt-in torque cams that work with stock valve springs in 1999-2004 engines. Like the S&S 551 cams, the 509 cams are great for low and midrange torque, but the 509 cam's lower lift allows them to be bolted into stock 1999-2004 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. The 509 cam also works great 2005-2006 Twin Cam 88 engines.
