WPC Treated Main Bearing Set

What's better than using new connecting rod 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 rod bearing service!
