S&S Cycle 330-0017 – 99-06 BT Gear Drive Camshaft Complete KitType: 509G; Timing Open: Intake 18º/Exhaust 46º; Timing Closed: Intake 18º/Exhaust 11º; Duration at 0.053: Intake 216º/Exhaust 237º; Valve Lift : Intake 0.509″/Exhaust 0.509″; Lift at TDC: Intake 0.174″/Exhaust 0.140″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. The S&S 551 cams for Harley-Davidson® touring bikesare a favorite with late model bagger riders. The problem is that, due to the .550″ lift, the 551 cams can’t be installed in early (1999-’04) Twin Cam 88® engines without a set of high lift valve springs. That means that the heads have to come off just to install a cam. That’s a lot of work and expense!S&S has come up with new 509 bolt-in torque cams that work with stock valve springs in 1999-’04 engines. 509 cams are great for low andmidrange torque, but the lower lift allows them to be bolted into stock 1999-’04 engines with stock valve springs. That saves time and money on the installation.
