King HP Chevy 350 Large Journal XP Main and Rod Bearing Kit

Camshaft Bearings

These connecting rod bearing sets from King Engine Bearings feature bi-metal aluminum construction and are narrowed for use with large radius crankshafts.

• Bi-metal aluminum silicon alloy featuring fine micro-bore finish
• Mains and rods are narrowed for large radius crankshafts
• Greater rod bearing height improves bearing-to-bore contact/heat transfer and reduces spin potential at high RPM
• 0.015" thick top layer for superior macro particle embedability and conformability
• 40 Vickers hardness to resist overlay migration and extrusion
• 450°F heat threshold for superior protection against friction and overheating
• Choose the size that suits you
• STD option: Rod bearing for Small Block Chevy, for 2.00" journal
• The X001 option will give .001" extra oil clearance
• The 001 option will gives you .001" less oil clearance

Crankshaft Bearings

• Enhanced tri-metal copper lead construction with nickel barrier and SecureBond adhesion 
• Unique SecureBond adhesion process for superior stability between the top and intermediate layers
• 15% - 30% greater load capacity than traditional bearings
• Mains and rods are narrowed for large radius crankshafts
• Greater rod bearing height improves bearing-to-bore contact/heat transfer and reduces spin potential at high RPM
• 0.0005" metallurgically enhanced and hardened performance overlay withstands greater loads and better resists surface fatigue
• Mains are 1/2 grooved for uncompromised lower shell load capacity

• High-load, short-duration racing such as drag racing, tractor pulls, monster trucks, etc.
• Medium-load, long-duration racing such as circle track engines using nodular cast iron crankshafts
