Crankshaft/Connecting Rod Bearing Sets

(OEM bearings are of the highest quality, which is all we sell. We provide many oversize and coated bearings. Coated bearings are 0.0003"-.0005" over stock bearing size, so you will need to compensate accordingly. If you need help figuring out the bearings you need please give us a call! Coated bearings are coated specifically for race conditions. Coatings have excellent anti-scuffing properties for all conditions. The coating is specifically designed to permeate the bearing surface, increasing oil retention to protect against intense heat and extreme pressure. This dramatically reduces bearing wear and flaking, and adds an extra level of lubricant to the bearing. This also protects the bearing from heat build up and excessive wear. Bearings come as a set, for individual bearings please give us a call!)
