With BDL’s EVO-10ST you can be reassured this drive can out last and out perform the competition. Our one piece 6061-T6 polished billet motor plate locks the transmission and engine together. All of these kits include a 3" wide belt drive unit with polished pressure plate, double row sealed mainshaft bearing, polished aluminum side plate and pulley covers and a complete Competitor Clutch with Kevlar plates. This kit is supplied with an optional oil filter mount centered in the motor plate. The kit allows the oil lines to be hidden out of the way. The kit also includes an All Balls starter. For installation in wide frame/tire applications, choose the appropriate insert to space the front pulley. For Shovelhead models from 1970-1978.
