Product Description
Give your common-rail Cummins the oil clearance it needs for hard work and high RPM with the MAHLE CB-1873HX H-Series connecting rod bearing. The HX (extra-clearance) design provides approximately .001" more oil clearance than standard H-Series—ideal for performance crankshafts with large fillets, boosted tow rigs, and competition builds that live in heavy load and heat.
