King Engine Bearings MB7084XPC XPC pMaxKote Main Bearing Set Toyota 2JZGE 2JZGTE

Vehicle Fitment

• Toyota 2JZGE (naturally aspirated, 3.0L 24V inline-6)
• Toyota 2JZGTE (twin-turbocharged, 3.0L 24V inline-6)
• Toyota 1JZGE (2.5L 24V inline-6 - shares main bearing specification)
• Representative vehicle applications: Toyota Supra JZA80 (1993-1998 | 2JZGTE), Toyota Aristo (1991-2000 | 2JZGE/2JZGTE), and all other 2JZ- and compatible 1JZ-powered vehicles including engine swap applications

Fitment Notes

• The MB7084XPC fits both naturally aspirated (2JZGE) and turbocharged (2JZGTE) variants of the Toyota 2JZ inline-6 engine, as well as the 1JZGE, which share the same main bearing journal specification.
• Available sizes: Standard (STD) - this listing, Standard with Extra Clearance (STDX), +0.026mm, and +0.25mm. Measure the crankshaft main journals before selecting a size. Consult your engine builder to confirm STD is correct for your specific build clearance targets.
• Sold as a complete set of 7 pairs (14 shells) - covers all 7 main bearing journals in the Toyota 2JZ inline-6 crankshaft. Upper shells feature a 3/4-groove oil distribution configuration.
• The "C" suffix in MB7084XP**C** denotes the pMaxKote™ polymer top coat applied over the pMaxBlack™ XP base - this is a 4-layer XPC bearing. The coating is factory-applied with no added wall thickness, maintaining the original bearing dimensions.
• The companion rod bearing set for the 2JZGE/2JZGTE is King Engine Bearings CR6754XPC.

Features

• pMaxKote™ XPC four-layer construction - the pMaxBlack™ XP tri-metal base (steel + copper-lead + nickel barrier + nano-hardened Babbitt overlay) is topped with pMaxKote™, a nano-composite polymer coating containing ceramic particles and solid lubricant that provides the most comprehensive main bearing protection available for 2JZ engine builds
• Oil starvation protection is the defining benefit for modified 2JZ applications - high-boost 2JZGTE builds under sustained wide-open-throttle at high RPM, drag race launches, and track use all create conditions where oil pressure and film thickness are momentarily compromised. The pMaxKote's ceramic and solid lubricant coating provides a protective barrier that prevents metal-to-metal contact damage during these critical events
• pMaxBlack™ XP base provides 24% stronger overlay and 17% more fatigue resistance versus conventional tri-metal race bearings - delivering the fundamental load capacity necessary for 2JZ engines producing power outputs far beyond factory specification, from mild bolt-on builds to 1,000+ horsepower competition applications
• U-Groove™ 90° oil groove geometry on upper shells maintains oil flow continuity while increasing the bearing's load-carrying surface area - the geometry is specifically optimized to prevent the oil flow disruption that conventional groove profiles create at the groove edges, preserving oil film integrity across the full main journal contact area
• 3/4-groove upper shell configuration provides optimal oil distribution to the main journals while retaining a larger plain bearing surface area on the lower shells for maximum load capacity - the configuration balances oil supply and load support across the 2JZ's 7 main bearing positions
• Narrowed design accommodates large-radius fillet grinds on aftermarket forged 2JZ crankshafts - providing proper fillet clearance without reducing the load-bearing contact area
• Enlarged, chamfered oil holes ensure consistent oil delivery to both the main journals and the connecting rod oil passages that feed from the main journals - critical for maintaining oil film integrity at all 7 main positions simultaneously under high-RPM demand
• Factory-applied pMaxKote™ with no added thickness - dimensionally correct at the stated nominal size with no clearance adjustment required versus the uncoated XP variant
• BullsEye Tolerance™ ±.0001" wall thickness across all 14 shells ensures consistent clearance at every main bearing position for uniform crankshaft load distribution
• EccentriX™ optimized eccentricity design provides stable hydrodynamic oil wedge formation for a consistent oil film throughout the crankshaft's rotation at all engine speeds

Product Description

The King Engine Bearings MB7084XPC is the XPC (pMaxKote-coated) main bearing set for the Toyota 2JZGE, 2JZGTE, and 1JZGE engines. It includes 7 pairs (14 shells) covering all 7 main bearing positions of the Toyota inline-6 crankshaft, with 3/4-grooved upper shells in U-Groove™ geometry. Standard size - consult your engine builder and measure crankshaft main journals before ordering. The companion rod bearing set is King CR6754XPC.

The 2JZGTE's reputation as the definitive high-power JDM inline-6 platform comes with specific bearing demands. Modified 2JZGTE builds running high boost, large turbos, high RPM, and aggressive valve timing create sustained bearing loads that exceed factory design parameters by significant margins. The pMaxBlack™ XP base addresses the fundamental load capacity requirement with 24% stronger overlay than conventional race tri-metal bearings. The pMaxKote™ layer adds the critical second dimension of protection - the ceramic nano-composite particles and solid lubricant in the polymer coating shield the bearing surface during the oil starvation scenarios that modified 2JZ builds are particularly prone to: high-G cornering, sustained high-RPM use, and the brief but critical oil pressure lag at engine startup when the bearings first load under boost.

King's U-Groove™ 90° oil groove design in the upper shells maintains oil flow integrity while maximizing load-bearing surface area - a geometric refinement that directly benefits the 2JZ's 7-position inline-6 crankshaft where consistent oil distribution across all positions under high-RPM demand is essential. The pMaxKote coating is factory-applied and dimensionally accounted for before final sorting, maintaining the nominal STD wall thickness with no additional clearance adjustment. BullsEye Tolerance™ at ±.0001" ensures clearance consistency across all 14 shells in the set.
