For engines with 9.5 to 1 or higher compression ratio and 88 to 95 CI (2600 to 6000 or higher RPM). TW50 GRIND 233000 Roller chain conversion cams for maximum torque and Horsepower at higher RPM range. For lighter bikes and engines with 9.5: 1 compression ratio and 88 to 95 cubic inch (2600 to 6000+ RPM). TW37 GRIND 232981 Bolt-in roller chain conversion cams Andrews claims that Twin Cam models with this bolt-in cam grind have shown 80+ rear wheel Horsepower. Smooth idle, broad torque band. Runs best with low restriction exhausts (2200 to 5800 RPM). TW31 GRIND 232980 Bolt-in roller chain conversion cams. Great for 96 CI motors with a compression ratio between 9.8 and 10.2. Similar to the TW37 but with a lower TDC lift for ease of installation (2000-5600 RPM). TW26 GRIND 232979 Bolt-in roller chain conversion cams for lower RPM torque in both carburetor and injection models (FLT etc.) For two up touring, this cam will add more torque and HP at lower and middle RPM range (1800 to 5500 RPM). TW21 GRIND 232704 Bolt-in roller chain conversion cams with more torque for all around riding with stock compression ratio, works great on heavy weight bikes (1700 to 5200 RPM). TW12 GRIND 232694 Bolt-in roller chain conversion cams with the same output as the stock cam. Slight power increase but no re-tuning necessary! Roller Chain conversion kits Kit includes oil pump assembly, cam support plate, screws, roller chains, tensioners, sprockets, and installation instructions. Matching conversion cams are not included but must be ordered separately. 750689 Fits 1999 thru 2001 FXD, FLH and FLT series models and 2000 thru 2002 Softail models 750690 Fits 2002 thru 2005 FXD models and 2002 thru 2006 FLH/FLT series models and 2002 thru 2006 Softail models The roller chain drive was introduced in 2006 on the Dyna models and commonly used from 2007 in all Twin Cam engines to replace the silent chain drive. The conversion kit exchanges the high power spring loaded chain adjuster for an oil pressure based system to maintain chain tension. Also the journal bearing on the sprocket end is replaced with a bigger and sturdier piece. Less wear and easy installation are direct results of these innovations. These conversion kits allow Twin Cam owners enhanced performance and prolonged engine life. You have to order a set cams from the list below, as well as a Roller Chain conversion kit for 1999 thru 2001 Twin Cam or 2002 thru 2006 Twin Cam. These kits include the late style oil pump that is required to let the oil pressure operated cam chain tensioners work properly, as well as all other parts required to install your Andrews Roller Chain Conversion cams. Please note that these conversion cams do not fit 2006 thru 2017 Dyna models, nor any other 2007 thru 2017 Twin Cam model. These cams are designed for use with stock hydraulic lifters. Matching EZ-install pushrod kits are also available, they are listed elsewhere in this chapter. 2054 ANDREWS ROLLER CHAIN CONVERSION CAMS FOR 1999 THRU 2006 TWIN CAM (Ȧ*ȡ1ȝ CAMS FOR TWIN CAM (Site 470)
