99-06 Twin Cam (excl. 2006 Dyna) (NU)
Part Description
Andrews, chain drive conversion camshaft set 31N/.510"
Great cam for 95" motors and 9.8 to 10.2 CR. Lower TDC lift for easy installation. Similar to TW37 with different timing. Works well with both carb and injection. Stock springs OK. 2200-5800 RPM. These cams are used to convert a 99-06 Twin Cam from the stock 'silent chain drive', which is equipped with spring adjusters, to the 'roller chain drive' with hydraulic adjusters that work on engine oil pressure. This roller chain and hydraulic chain adjusting system, which is much better than the early system, is used in all 06-17 Dyna and 07-17 Softail and 07-16 Touring models. Note: Cams are for use with splined (00-up style) driven gear. For 1999 Twin Cams splined 503575 driven gear must be purchased separately. Note: See our catalog for additional required parts.
