For 06-17 Twin Cam models Harley improved the chain drive with new hydraulic chain tensioners. This system is more suitable for high performance applications. Note: Owners of 1999 Twin Cams must separately purchase the splined 00-06 style driven gear (503575 Andrews). 00-06 models can re-use stock 34 tooth driven gear. Application recommendations: 99-06 Twin Cam (excl. 2006 Dyna) OES: Bolt-in stock replacement. OES (Original Equipment Specification) cams are suitable for those that wish to replace the stock camshaft but retain stock timing specifications as found in the OEM A-grind camshafts 510C: Bolt-in 88" to 95" with up to 9.7:1 CR (unported heads) 3000-5500 RPM MR103: Not bolt-in. For modified big engines, larger displacement & higher CR. High lift springs, stock valve springs for 05-06 engines only HP103: Not bolt-in. For modified big engines, larger displacement & higher CR. High lift springs, stock valve springs for 05-06 engines only 635HO: Not bolt-in. For modified big engines, larger displacement & higher CR. Hi-lift springs required 06-17 Dyna; 07-17 Softail; 07-16 Touring 510C: Bolt-in 88" to 95" with up to 9.7:1 CR (unported heads) 3000-5500 RPM 551C: Bolt-in torque for stock 96" Touring bikes.

Short duration with lots of usable torque 570C: Bolt-in 88" to 103" with 9:1 to 10:1 CR. 3200-5700 RPM overall power increase HP103: Bolt-in cams for stock 103" engines with stock 9.7:1CR up to 10.5:1CR. Works well with un-ported heads and great for S&S CNC ported heads. Best power in the higher RPM range. 3000-6000 RPM 583C: Bolt-in. 88 to 103" engines with compression ratios up to 10:1 and 106" to 124" engines. Not recommended for 10:1 or higher CR. Provides excellent torque from 3000 RPM. 1500-5000 RPM range 585C: Bolt-in 88" to 106" with 9.7:1 to 10.5 CR and 106" to 124" with 9:1 to 10:1 CR. 3500-6000 RPM for 88" to 103" and 2500-5500 for larger engines 625C: 95"-up with 10.0:1 to 10.8:1 CR 640C: 95"-up with 10.5:1 to 11.5:1 CR (stock in S&S 124" engines) 99-06 Twin Cam (excl. 2006 Dyna) Kits includes camshaft installation kit. Note 1: Not to be used with S&S 79cc heads. Note 2: When using 99-06 chain drive cams for lifts over .510", S&S strongly recommends that the stock chain drive be upgraded to the S&S gear drive or to convert to 06-up hydraulic chain tensioners. 531839 509 503602 510 592012 MR103 (note 2) 592006 HP103 (note 1, 2) 06-17 Dyna; 07-17 Softail; 07-16 Touring 532596 OES cams, .474" lift (bolt-in, OEM grind) 531692 510C (bolt-in) 531690 551C (bolt-in) 564000 557C (bolt-in) 531693 570C (bolt-in) 532597 HP103, .575" lift (bolt-in) 564001 583C (bolt-in) 531694 585C (bolt-in) 531695 625C 531696 640C Camshaft installation kit Kits includes camshaft installation kit. 503593 99-06 TCA/B (excl. 2006 Dyna) 531691 06-17 Dyna; 07-17 Softail; 07-16 Touring 503602 503593 531691 510 Camshafts supplied will be 00-06 style, for use with splined style 34T driven gear. The S&S 551 Touring cams deliver an extra 10 ft/lb of torque in the low and mid-range where touring is done. This translates to safer passing and increased up-hill performance. Chain driven cams re-use the stock chain drive system, which makes them cost effective. For 06-17 Dyna; 07-17 Softail; 07-16 Touring models The Factory improved the chain drive system and it is therefore suitable for use with hotter cams.
