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. Of course, the 509 cam also works great in 2005-'06 88 engines, except 2006 HD® Dyna® models.
