ACL Race Series are tri-metal main bearings designed for demanding high-RPM engine conditions. Their combination of design, metallurgy and engineering supports stable bearing operation.
Increased eccentricity helps compensate for bore distortion at high RPM and assists in the formation of hydrodynamic oil films.
- 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 increased grip between the bearing and its housing.
- 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 maintain consistent clearances.
Suitable for: Saab 9-3 I (YS3D), Saab 9-5 I (YS3E), Saab 9000 I, Saab 900 I / II.

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.
