Clevite MS-2339A-30 Main Bearing Set

Clevite MS-2339A-30 is an OE replacement engine crankshaft main bearing set for GM V8 applications that require .030 in undersize bearings. It uses a bi-metal aluminum construction with a lead-free aluminum silicon surface for dependable journal support in high-load street and performance use.

Key Features

  • Bi-metal aluminum bearing construction
  • 100% lead-free aluminum silicon material
  • 60% more silicon than comparable competitive replacements
  • Improved journal surface conditioning
  • Greater seizure and wear resistance
  • .030 in undersize specification
  • F1 coated surface

Application Details

Compatible with 2014-2018 Chevrolet Silverado 1500, 2014-2018 GMC Sierra 1500, 2014-2019 Chevrolet Corvette, 2015-2020 Cadillac Escalade, 2015-2020 Cadillac Escalade ESV, 2015-2020 Chevrolet Tahoe, 2015-2020 GMC Yukon, 2015-2020 GMC Yukon XL, 2016-2019 Cadillac CTS, 2016-2020 Chevrolet Camaro, 2019 Chevrolet Silverado 1500 LD, and 2019 GMC Sierra 1500 Limited. This part number, MS-2339A-30, is listed for N/A position applications and is an OE replacement with A Series aluminum construction.

MS-2339A-30 is used in engine rebuilds where crankshaft main bearing clearance must match an undersize journal specification. It supports proper oil film control and bearing surface conditioning in engines that have been machined for .030 in undersize main bearings.

Common Repair Uses

  • Restores crankshaft main bearing clearance after machining
  • Addresses bearing wear from high mileage or oil contamination
  • Helps correct scoring or seizure-related bearing damage
  • Supports rebuilds after crankshaft journal refinishing
  • Replaces worn OE-style main bearings in GM V8 engines

Installation Notes

Verify crankshaft journal size, bearing clearance, and engine code before installation. Clean all oil passages, inspect the crankshaft for taper or out-of-round conditions, and follow factory torque and lubrication procedures during assembly. Confirm that the engine has been machined for .030 in undersize bearings before using MS-2339A-30.

Quality Assurance

Clevite engine bearings are built around a durability-focused OE replacement design. The aluminum silicon bearing material and F1 coated surface are engineered to improve journal conditioning and resistance to wear in rebuilt engines.
