King Engine Bearings has introduced a new simplified numbering system for its performance engine bearings.
Under the new system, King Engine Bearings retains the "core number" from the OE replacement bearing and changes the suffix to reflect material and features.
"Our new part numbers make it easier for engine builders and race teams to select the right bearing for their project," said Limor DePetro, director of sales and marketing, King Engine Bearings.
Reflected in the new numbering system is King's decision to narrow its rod bearings instead of chamfering.
"We removed the large chamfer and narrowed the bearing by the corresponding amount," explained DePetro. "Many customers prefer the narrowed bearing, which is cleaner and more professional looking. All eight cylinder rod bearings will feature the N (narrowed) design."
All King performance bearings feature greater rod bearing height that improves bearing to bore contact/heat transfer and reduces spin potential at high RPMs. Main bearings feature enlarged, chamfered oil holes and ¾ grooving. In addition, most rod bearings are available with or without dowel holes. King bearings feature the closest wall tolerances in the industry (Bull's Eye Tolerance), with all shells matched to .0001". Main and rod bearings are narrowed for large radii crankshafts.
