Camshaft upgrade for all 99-06 engines.. . Installing 2007 roller cam chains on earlier engines requires series "N" Andrews camshafts, Stock H-D parts are required: 2007 cam support plate, 2007 or later oil pump, cam sprockets and chains and both hydraulic chain adjusters. Matching EZ-install pushrods kits are sold separately. EZ-install pushrods do not require removal of gas tanks or rocker boxes when installing bolt-in camshafts.. . 12N: Bolt-in cams for 99-06 engines; Similar cam time to stock 88 engines for cooler running and more power.. 21N: Bolt-in cam more torque for all around riding with heavy bikes, stock compression ratios and stock pistons; Similar to #23 cam for EV80. (1700-4800rpm).. 26N: Bolt-in cam 88"-95" and stock compression ratio; Great for two up touring, this cam will add torque and HP at lower and middle RPM ranges (1800-5200rpm).. 37N: Hot street cams for 88" or 95", 80+ rear wheel HP possible with well tuned 88", more with 95; Smooth idle, broad torque (2200-5600rpm).. 48N: Broad tip cams for baggers with stock motors; Max torque at low and mid RPMs; High lift springs needed for 99-04 engines.. 50N: Designed for easy installation in 95" motors with stock heads and 9.5 to 9.8 CR. (2400 to 6000rpm).. 54N: Great cam for 95" engines with CR to 10:1 (2200-5600rpm range). Added to the conversion cam group by popular demand.. 55N: Great cam for 95" with 9.8 to 10.2 C.R.; Max HP - torque at mid and upper RPMs (2600 to 6200).. 67N: Performance cams for 95"-107" + 10.0 to 10.8 CR with high-flow head setup.(2600 to 6400+ rpm).
- Eliminate spring powered chain adjusters
- Engines converted to 2007 type cams and chain drives will have higher output due to less power loss from older spring powered chain tensioners; instead, of the original spring adjusters, new roller cam chains use engine oil pressure to maintain proper chain tension
- Camshafts on all 99-06 Twin Cam 88 engines (exc
- 2006 Dyna) can be updated to new style roller chain drives
- Designed for use with stock H-D hydraulic lifters.
