This proprietary, patent-pending kit engineered by “SS” uses a stock VW crankshaft. No welding! Bolts right on. Best of all, there is no need to split the case to install it!
Using the same mechanism designed to hold tight tolerance at 15,000 rpm and much higher torque values, this kit will hold your 2,500 rpm VW crankshaft just fine without the risk of shearing off welded extension ends and totalling your engine.
