98+ Toyota 1ZZFE & 2ZZGE Standard Size Thrust Washer - ACL Bearings

• High performance Trimetal engine bearings
• Designed to withstand higher RPM conditions
• High strength overlay plate with reduced thickness for improved fatigue properties

Bearing Material Enhancements 

A blend of characteristics to provide high strength and crankshafts. excellent seizure resistance.
No flash plating is applied to further improve bearing retention and maximize heat transfer.
ACL Race Series performance engine bearings are identified from the standard range by the following suffixes:

• H = ACL Race Series
• HX = ACL Race Series with 0.025mm (0.001”) extra clearance
• HD = ACL Race Series with location dowel holes.*
• HXD = ACL Race Series with 0.025mm (0.001”) extra clearance and location dowel holes.*

*Connecting rod bearing applications only

• HIGH STRENGTH OVERLAY PLATE with reduced thickness for improved fatigue properties
• HARDENED STEEL BACKS on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
• INCREASED CRUSH for improved bearing retention
• ELIMINATION OF FLASH PLATING on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing.
• INCREASED ECCENTRICITY to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.
• 3/4 GROOVED MAIN BEARINGS to optimize bearing load carrying surface area and oil flow to the conrod bearings.
• TIGHT CONSISTENT WALL TOLERANCES to help you maintain consistent clearances.
• ENLARGED ID CHAMFERS on bearing edges where required to accommodate large fillet radius on performance crankshafts.
