Per ACL's own fitment data it's used across GM's full-size trucks and SUVs (Chevrolet Silverado, Suburban, Tahoe, Avalanche; GMC Sierra, Yukon; Cadillac Escalade) and GM LS-powered performance models (Corvette, GTO, Impala SS, Trailblazer SS, Saab 9-7x, Pontiac G8). Main bearings support the crankshaft in the engine block and are matched with rod bearings to control bottom-end clearances.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: Main Bearing Set\u003c\/li\u003e\n\u003cli\u003eSeries: Race Series\u003c\/li\u003e\n\u003cli\u003eSize: Standard, Extra Oil Clearance\u003c\/li\u003e\n\u003cli\u003eEngine Fitment: GM LS Gen III-IV 4.8\/5.3\/5.7\/6.0L V8\u003c\/li\u003e\n\u003cli\u003ePart Number: 5M7298HX-STD\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat does \"Extra Oil Clearance\" mean?\u003c\/h5\u003e\u003cp\u003eExtra oil clearance bearings run a slightly looser clearance than standard, which some high-RPM, high-oil-volume, turbocharged, or boosted applications prefer for additional oil flow and thermal margin.
