ACL Race main bearings for Nissan VQ35DE / VQ20DE / VQ30DET …

ACL Race Series main bearings use a tri-metal construction with a high-strength overlay, designed for increased loads and higher engine RPM.

The set is designed to support the crankshaft, maintain efficient oil flow and provide consistent operating clearances. Includes an ACL Race Series main bearing set.

• High-strength overlay with reduced thickness for improved fatigue properties
• 3/4-grooved main bearings to optimize bearing load-carrying surface area and oil flow
• Increased eccentricity to compensate for bore distortion at high RPM and assist in forming hydrodynamic oil films
• Tight, consistent wall tolerances to help maintain consistent clearances
• Enlarged ID chamfers where required to accommodate large fillet radii on performance crankshafts

Suitable for: Nissan 350Z I (Z33), Nissan Stagea II (M35/NM35).

Engines: VQ35DE, VQ20DE, VQ30DET, VQ25DE, VQ30DE, VQ25DET. 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.
