This kit includes the basic components needed to replace S62 rod bearings, OE connecting rod bolts and WPC-treated rod bearings. 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. Kit includes: Upper and lower WPC-treated rod bearings for extra protection against wear Connecting rod bolts

The S62 engine has a known history of rod bearing failure. If your engine is higher mileage, don't let this catastrophic failure happen to you. Replace your rod bearings and prevent a spun bearing, a failure that has the potential to trash your crankshaft.

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!

Kit Includes:

Turner Motorsport "Race Series" WPC-Treated Rod Bearing Shells (16) Genuine BMW Connecting Rod Bolts (16) OEM Hengst Oil Filter Kit Castrol Edge Euro Car Engine Oil (10w-60) - 7 Quarts Turner Oil Change Decal Elring Oil Pan Gasket Permatex Ultra Slick Engine Assembly Lube (4 oz.)
