For lighter bikes and engines with 9.5: 1 compressionratio and 88 to 95 cubic inch (2600 to 6000+ RPM). 700833 Silent Chain version 232599 Roller Chain version TW37 GRIND For both carburetor and injection models. 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). 700832 Silent Chain version 232597 Roller Chain version TW31 GRIND Great cam for 95 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). 232522 Silent Chain version 232596 Roller Chain version TW26 GRIND Bolt-in 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). 700831 Silent Chain version 232595 Roller Chain version TW21 GRIND Bolt-in cams with more torque for all around riding with stock compression ratio. Works great on heavy weight bikes (1700 to 5200 RPM). 700841 Silent Chain version 232594 Roller Chain version Since the Twin Cam engines became available, their potential for more performance has already become an established fact. Andrews has designed and tested new cam grinds which show that more power is within reach. The Twin Cam has a very broad torque curve compared to earlier engines. All of the Andrews performance cams are intended for use with the stock hydraulic lifters and Andrews EZ-Install push rods in anodized aluminum or chrome-moly steel. EZ-Install push rods do not require removal of tanks or rocker boxes for installation. Andrews also offers a heat-treated 34 teeth rear cam drive sprocket for late Twin Cam models. Early Twin Cam models have the gear fitted to the cam with a key, where later models have a splined camshaft and gear. These sprockets are made from heat-treated alloy steel with a wider than stock press fit for greater stability. Gears are highly recommended for use in your stock engine but must be used with any Andrews cams. Gears are not included with the cams, they must be ordered separately. Andrews cams are available for all Twin Cam models. "Silent Chain" version fits 1999-2006 Touring, 2000-2006 Softail and 1999-2005 Dyna, "Roller Chain" version fits 2007-2016 Touring, 2009-2016 Trike, 2007-2017 Softail and 2006-2017 Dyna. 2052 ANDREWS CHAINDRIVE CAMS FOR TWIN CAM CAMS FOR TWIN CAM (Ȧ*ȡ1ȝ (Site 469)
