ACL Race main bearings for Nissan RB26DETT

ACL Race main bearings for Nissan RB26DETT feature a trimetal construction developed for higher engine RPM. The combination of design, metallurgy and engineering improves bearing durability in demanding applications.

The main bearings use 3/4 grooves to optimize bearing load-carrying surface area and oil flow to the conrod bearings. Increased eccentricity helps form hydrodynamic oil films and compensates for bore distortion at high RPM.

• Trimetal construction with a high-strength overlay plate and reduced thickness
• Eliminated flash plating on the back for improved heat transfer and grip in the housing
• Increased crush for improved bearing retention
• Tight, consistent wall tolerances to help maintain consistent clearances
• Enlarged ID chamfers to accommodate large fillet radii on performance crankshafts

Suitable for: Nissan Skyline I (R32) / II (R34) / III (R33).

Engines: RB26DETT. Please check your vehicle’s engine code (registration document or VIN) before ordering; if in doubt, contact us and we will check for you.

Sizes

STD is the standard size for an unground crankshaft. Undersizes (−0.25 mm, −0.50 mm …) are for a reground crank, and “+0.025 mm clearance” (X) is for highly stressed engines. Your machine shop chooses the size after measuring.
