The world's strongest Triumph crankcases are being manufactured by Donny Coveney in Australia.
CNC machined from aircraft grade "6 series" aluminum alloy, rather than cast like others, ensures accuracy and consistency of every pair. These cases are the ideal foundation if you fancy a Triumph that puts out double the power of any Twin that came out of Meriden. Capable of handling the horsepower from big bore cylinders, hot cams, nitro fuel, stroker cranks, and superchargers without coming apart at the seams.
Supplied with a timing cover set up for RH crank seal and RH ignition as used on unit Triumphs, but maintaining the ability to run the original rear mounted ignition, these cases have got most every option covered when putting a motor together.
Designer Donny, has used these cases in roadracers and dragracers that produce 90 plus horsepower, and are capable of taking much more.
They come Complete with hardware, these cases incorporate many improvements over stock Triumph cases, and are definitely the way to go if building a Triumph to be reckoned with.
Allen bolts are stainless, base stud inserts are 4140 chromoly, and cases are supplied ready to accept 72mm Superblend crank bearings for the ultimate in reliability.
