Engine & Performance Warehouse CB1459P4020 Connecting Rod Bearing Set Oversize - 0.020

The Engine & Performance Warehouse CB1459P4020 is a connecting rod bearing set ground to a +0.020" oversize specification, designed for use during engine rebuilds where connecting rod journals have been machined undersize. These precision-ground bearings restore proper oil clearances and ensure reliable performance in rebuilt engines.

Key Features:

• +0.020" oversize (0.020" over standard journal diameter) for use with reground crankshafts
• Precision-machined to tight tolerances for optimal oil film and bearing clearance
• Engineered for durability under high-load, high-cycle engine operating conditions
• Tri-metal or bi-metal construction typical of premium engine bearings for superior wear resistance
• Designed as a direct replacement for OEM connecting rod bearings
• Suitable for use in performance engine rebuilds and standard restoration applications

Connecting rod bearings (also referred to as rod bearings or big-end bearings) are a critical component in any engine rebuild. The CB1459P4020 oversize specification allows machinists and engine builders to correctly fit bearings to a crankshaft that has been turned 0.020" undersize, maintaining proper oil clearance and protecting the crankshaft and connecting rods from premature wear.
