ACL race bearings are manufactured with a tri-layer metal in order to withstand high RPM conditions, high stress loads, and high temperatures. Each ACL race bearing design features the following:
*Large chamfer to accomodate larger crankshaft fillets
*3/4 groove main bearings to optimize bearing load carrying capacity and oil flow to rod bearings
*3/4 groove to provide optimum oil supply to rods and to maximize load carrying capacity
*Incresed crush and tighter wall tolerance for better seating
*Improved overlay and reduced thickness for increased fatigue strength
*Hardened steel backing to maintain crush under high loads and temperatures
ACL thrust washers are an often overlooked component of rebuilds. They prevent the crankshaft from moving around, thus keeping it in line with all of the other critical moving engine parts. It also helps the crankshaft to better stand up to stresses from clutch and flywheel operation.
Kit comes with 1 full set of main bearings, 1 full set of rod bearings and 1 full set of thrust bearings
