ACL Race main bearings for Nissan MR16DDT

ACL Race main bearings are trimetal engine bearings developed for demanding conditions and higher engine RPM. Their combination of design, metallurgy and engineering improves bearing retention in the housing and heat transfer.

Increased eccentricity helps compensate for bore distortion at high RPM and assists in forming a hydrodynamic oil film. The set includes ACL Race Series main bearings.

• High-strength overlay plate with reduced thickness for improved fatigue properties
• Increased crush for improved bearing retention in the housing
• Elimination of flash plating on the back for improved heat transfer and grip in the housing
• 3/4-grooved main bearings to optimize bearing load-carrying surface area and oil flow
• Tight, consistent wall tolerances to help maintain consistent clearances
• Enlarged ID chamfers to accommodate a large fillet radius on performance crankshafts

Suitable for: Nissan Juke I (F15), Nissan Tiida I (C11X).

Engines: MR16DDT. 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.
