S54/S5X/M5X/M20/M44 WPC Treated BMW Engine Crankshaft Main Bearing Set (Standard/Yellow Shell)

Product Details

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!
