ACL RACE / KING RACING tri-metal big end bearings, TOYOTA 1JZ 2JZ GE/GTE

Below (click on the image) you will find the tri-metal main bearings for the 1JZ 2JZ GE/GTE engine and the plastigage strips used to check the bearing/crankshaft running clearance:

Technical specification

ACL Race Series tri-metal bearings are manufactured to exacting tolerances. CNC machining works to the micron, ahead of metrology checks on the diameter, thickness and width of the ACL Race Series tri-metal bearing. ACL Race Series bearings therefore give a reliable and consistent fit in your performance engine. ACL Race Series tri-metal bearings are in fact made up of four layers:

• SAE1010 steel on the outside
• 0.3mm copper alloy
• 0.0001mm nickel
• copper alloy from 0.013 to 0.018mm

This choice of materials, combined with the manufacturing processes, makes ACL Race Series tri-metal bearings more resistant to increases in power, torque and engine speed. The compressive strength of ACL Race Series tri-metal bearings brings reliability to your engine even on turbo or supercharger builds running high boost, or on sharp engines turning high revs.

Technical specification

Since 1960, KING RACING has designed and manufactured high performance, high quality bearings. Beyond its high-output production machinery, King Racing relies on simulation software to analyse the thermodynamics, dynamics and elasto-hydrodynamics of its bearings. KING RACING tri-metal bearings are made from pMax Black, a tri-metal alloy 24% stronger than any existing tri-metal bearing.

KING RACING bearings are made up of three to four layers, depending on the application:

Outer: steel Intermediate: lead bronze Inner: babbitt with a high copper content Anti-friction coating containing lubricant and ceramic additives
