The Rod Bearing GM Duramax 01-16 is a critical engine component engineered for the legendary Duramax diesel platform, trusted by mechanics and enthusiasts who demand reliability under extreme load and heat cycles. As a connecting rod bearing, this component directly supports the mechanical connection between the piston and crankshaft, managing thousands of compression strokes daily while sustaining the massive cylinder pressures that define diesel performance. Whether you're rebuilding an engine after high-mileage service, upgrading fuel injection systems, or restoring a Duramax to factory specifications, selecting OEM-specification bearings is non-negotiable for engine longevity.
Manufactured by MAHLE ORIGINAL/CLEVITE under MPN CB1990P, this bearing delivers the precision bearing clearance and surface composition required for optimal oil film strength and heat dissipation in the Duramax's high-compression environment. The P-Series standard specification ensures compatibility with factory crankshaft and connecting rod dimensions, eliminating costly guesswork during engine assembly. Premium bearing material composition resists scuffing and maintains stability across the wide operating temperature range typical of diesel engines, from cold starts to sustained high-load scenarios that push turbo boost and injection timing to their limits.
Diesel technicians and engine builders targeting 2001–2016 Duramax applications—whether LB7, LLY, LBZ, LMM, or LML generations—rely on this bearing for complete engine rebuilds, performance machine work, or damage recovery after detonation or lubrication failure. Installation requires proper alignment tools and torque specifications matched to your connecting rod design; always reference your engine service manual and pair these bearings with fresh oil, correct filtration, and a full bearing set for optimal results. This is a per-bearing unit sale, so confirm your engine's total bearing count before checkout.
