King Engine Bearings CR4515XP025 Performance Connecting Rod Bearing Set Ford Mazda Duratec 2.0L

King Engine Bearings CR4515XP025 is a high-performance connecting rod bearing set engineered specifically for Ford and Mazda Duratec 2.0L (121ci) 16-valve engines. This XP Series bearing set features King Racing's advanced pMax Black tri-metal construction, designed to handle extreme loads in demanding racing applications with forged steel aftermarket crankshafts.

pMax Black Tri-Metal Technology:

• 24% harder than conventional tri-metal race bearings for superior load capacity
• Enhanced copper-lead construction with nickel barrier layer
• 0.0005" metallurgically hardened performance overlay resists surface fatigue
• SecureBond adhesion process ensures stability between layers
• 15-30% greater load capacity than traditional bearings

Precision Engineering Features:

• Bulls Eye Tolerance: Industry-leading wall tolerances with all shells matched to 0.0001"
• Increased bearing height: Improves bearing-to-bore contact and heat transfer while reducing spin potential at high RPM
• Medium eccentricity design: Optimizes load distribution and improves oiling
• Narrowed design: Accommodates large-radius crankshafts
• Available with or without dowel holes for flexible installation

Ideal Applications:

• Circle track racing with extended high-load conditions
• Off-road racing applications
• Performance builds using forged steel crankshafts
• High-RPM competition engines requiring maximum durability

This oversized bearing set (0.025" oversize) is specifically designed for engines that have undergone crankshaft grinding or require oversized bearings for proper clearance. King Racing's XP Series represents the pinnacle of performance bearing technology, combining advanced metallurgy with precision geometric features to deliver uncompromising reliability under extreme racing conditions.
