Race Series Features
ACL Race Series bearings combine design, metallurgy, and manufacturing processes to support high-performance and high-RPM engine operation.
- High-strength overlay plate with reduced thickness for fatigue resistance
- Increased bearing crush for housing retention
- No flash plating on bearing backs, supporting heat transfer and housing grip
- Increased eccentricity to compensate for bore distortion and support oil-film formation at high RPM
- Tight, consistent wall tolerances for stable bearing clearances
- Enlarged inside-diameter chamfers to accommodate large-fillet-radius performance crankshafts
Before Ordering
Confirm the part number, engine application, groove specification, journal dimensions, and required assembled clearance for your build. This listing is for the 5M7298HXX-STD set with .002 in. extra clearance, not the HX version with .001 in. extra clearance. Extra oil clearance is not the same as a crankshaft undersize.
