Here are some photos of the updated drum.It uses a mechanical diode attached to a CNC inner race that registers on the stock 350 direct drum ,BOP style with removable race .Uses reprofiled laser cut steel plates and late 4R75W carbon fibre clutches.Combined w/ our billet output and input we can go way beyond the latest industry limits with available partsAlso some pics of the beefed up areas of the worlds strongest 4L80E input shafts available in 4340,300m,and maraging steel .Take note of improved areas.These are where stock and aftermarket shafts of hi quality material fail when the undercuts arent deleted from the design.
