These are Complete BOLT-ON kits that'll upgrade your 1970-84 4 speed to a 1990 style drive train with a splined shaft 6-SPEED POWERDRIVE LSD TRANSMISSION, a MONSTER-TORQUE 1.4 KW STARTER MOTOR (while retaining the stock oil tank), tied directly to a BRUTE IV EXTREME 3" OPEN BELT DRIVE w/PRO-CLUTCH.
All the benefits of proven, new technology. You get rid of your tapered shaft clunky 4 speed and get a CLOSE-RATIO 6-SPEED left side drive splined shaft TRANSMISSION & MOUNTING PLATE already modified to fit your FX or FL-style 4 speed swingarm frame. You can even retain the stock battery & box in their original locations. Now you've got the good stuff, close-ratio gears, forged & back-cut for positive shifting together with an overdrive .860:1 sixth gear, great on the highway.
Then there's the PRIMO OPEN BELT DRIVE, together with our world famous PRO-CLUTCH. It's a 3" WIDE, 8MM OPEN DRIVE KIT complete with front & rear pulleys, a polished one-piece motor plate, 3" belt, complete PRO CLUTCH kit & a fully polished billet aluminum outer guard (optional mounts are available for mid-control shifting as well as oil filter mounting).
