Our friends at MAHLE Aftermarket have announced a huge upgrade for the bottom end of the GM GEN-V LT1/4 engine platform! When stepping up the horsepower and/or boost it’s important to have a rotating assembly that’s up to the task at hand.
Official Release:
MAHLE Aftermarket Announces New H and V Series Coated Performance Bearings
Farmington Hills, MI (October 30, 2018)Ā Clevite, a leading brand under MAHLE Aftermarket, offers three new coated bearing applications for high horsepower engines designed to add durability and less distortion at higher RPM levels.
New stock options include a performance coated H-Series connecting rod bearing set for the GM 200-229 cid V6 (part #CB-1227HK). Previously available as a custom order, the new H-Series connecting rod bearing set features a fluoropolymer-based coating that adds protection in extreme hot and cold weather, reduces friction to fight dry starts, and ensures long-term durability with less wear for high load engines.
Clevite H-Series bearings, originally developed for NASCAR,utilize a medium level of eccentricity,which helps keep rod housing bore deflection and deformation to a minimum. Additionally, high crush helps to ensuregood heat transfer and resistance to rotation under minimum oil film conditions in the engine.
For enthusiasts competing in diesel drag and tractor pull competition, Clevite now offers V-Series bearings for the Dodge Cummins 5.9L with a performance coating (part # CB-1413VK and MS-2328VK), for engines that push 2,500 horsepower. The new performance coated bearings reduce friction and drag for increased horsepower and resist breakdown under high-load conditions.
Additionally, Clevite now offers a Teflon-based, performance-coated camshaft bearing set for the Generation-V GM 6.2L V-8 small block (part #SH2231S) that may be used for high output boosted LT1 and LT4 engines that have increased valve spring pressures.
