King Engine Bearings CR 868HPN.026 HP-Series Connecting Rod Bearing Set Ford V8 4.6L/5.4L SOHC

The King Engine Bearings CR 868HPN.026 is a high-performance connecting rod bearing set engineered for Ford V8 4.6L and 5.4L SOHC engines. Part of King's renowned HP-Series, these bearings feature the proprietary Alecular™ bi-metal construction — an aluminum/tin/silicon alloy top layer bonded to a high-strength steel backing — delivering a harder bearing surface than conventional tri-metal designs while maintaining excellent embeddability.

The HP-Series was developed specifically for demanding race applications that require a material harder than a traditional Babbitt overlay, making these bearings a top choice for drag racing, tractor pulls, monster truck, and other high-load, short-duration events. They are also well suited for medium-load, long-duration applications such as circle track engines equipped with nodular cast iron crankshafts.

Key Features:

• Alecular™ Bi-Metal Construction — Aluminum/tin/silicon alloy top layer bonded to a high-strength steel back for superior hardness and load resistance
• 0.015" Thick Top Layer — Provides superior macro particle embedability and conformability
• 40 Vickers Hardness — Resists overlay migration and extrusion under extreme load conditions
• 450°F Heat Threshold — Nearly 30% greater than tri-metal bearings (450°F vs. 350°F) for superior protection against friction and overheating
• Narrowed Profile ("N") — Designed for use with fillet-radius crankshafts
• Bull's Eye Tolerance™ — Industry-leading wall thickness precision with all shells matched to 0.0001"
• Greater Eccentricity — Optimized for superior oiling at high RPM
• Fine Micro-Bore Finish — Enhances oil film retention and bearing surface performance
• Size: .026mm undersize — for crankshafts ground to this specification

King Engine Bearings has been a specialist in precision engine bearings since 1960, and every HP-Series bearing is engineered to withstand the highest loads and RPMs found in today's top competition engines. The CR 868HPN.026 is an ideal upgrade for high-performance Ford Modular V8 builds where standard tri-metal bearings have proven inadequate.
