Crankshafts for BMW 3 Series E30 (1984-1991)

Clear BMW chassis

The engines crankshaft takes all of the explosive energy from the pistons and translates this to the drivetrain. When bearings spin due to improper maintenance or oil starvation, the shaft can become scored and is no longer serviceable.

What's better than using new crank bearings in your next engine build? WPC-treated bearings! What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. What are you waiting for? Use WPC-treated bearings on your next engine build or crank service!
