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 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 Twin Cam 88 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 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.

Put in my 2006 Electra glide ultra classic had 42K miles feels like a new bike also paired it with a dyno jet tuner. Can really feel the torque in the bike now pulling the hills here in the pacific north west.

These are great cams for low to mid range power increase, and a nice lope at idle, but needed a fuel controller (tuner) to make it work right, true duals are next.

Answer QuestionThe 509C is going to be a chain driven cam, like stock. The 509G cam will be a gear drive cam. S&S recommends using their adjustable push rods or Quickee push rods when using their cams.
By Anon.
Answer QuestionYes, you could removed the rocker box and arms in order to pull the push rods out to allow room for installation. This kit comes with new bearings for you to install as part of the job.
By Joshua P.
Answer QuestionYou do not need a new cam chain. You can simply reuse the cam chain with this kit.

Answer QuestionIf you would like to get the most out of the addition of those cams, I would recommend a tuner or to have your bike tuned professionally.
By Chris
Answer QuestionYes, if you were to choose the 1999 Harley Davidson FXD Dyna Super Glide 509C chain drive cams from our fit guide, you'd receive the correct cams to fit your machine. There's no need to purchase any gears or special valve springs to fit this to your bike since the .509" lift works with all remaining stock valvetrain components. Everything you need in one kit!
