ACL Tri-Metal "Race Series" Bearings: EVO 10

Probably the best bearings you can buy for your engine. These bearings have a unique tri-metal (lead-tin-copper) overlay that give them among the highest fatigue strength in the industry. Designed to withstand high RPM conditions and the extra stresses and loads of high HP applications.

NOTE: In the drop-downs below, for bearing sizes, "oversize" refers to the fact that the bearing is thicker (or "oversized") to accommodate the wear in the crankshaft journals. This can seem a bit confusing since the ID (inner diameter) of the bearings is actually smaller to accommodate the smaller diameter crank journals. Similarily, the "undersize" designation refers to the fact that the bearing is thinner (or "undersized") to allow for more oil clearance between the bearing surface and the crank journal surface. We've chosen to use these designations because they are the industry standard designations. It should be noted that the OD (outside diameter) of all the bearings in the drop-downs are of standard size, only the ID varies. The above notation applies to both main and rod bearings.
