Achieving the correct oil clearance is the most vital step in any engine rebuild. The Calico Coatings H-Series Main Bearing Set (MS909H19) is designed for Small Block Chevy engines requiring a 0.019 undersize fitment. These bearings are more than just standard replacements; they feature Calico’s signature dry-film lubricant coating, which is specifically formulated to mitigate wear during the critical break-in period and under high-stress racing conditions.

Why Choose Calico Coated Bearings?

• Friction Reduction: Proprietary coating minimizes heat and drag for increased efficiency.
• Superior Load Capacity: H-Series design supports high-horsepower output.
• 0.019 Undersize: Precision-machined for specific crankshaft journal requirements.
• Enhanced Protection: Provides a safety buffer during oil pressure fluctuations.

The H-Series construction is renowned for its ability to handle the rigors of competitive motorsport. By utilizing these coated bearings, you significantly reduce the risk of bearing failure, even when pushing your engine to its limits. The coating acts as a sacrificial layer, protecting the underlying bearing material while promoting a smoother, more reliable engine operation. If you are performing a crank grind and need exact 0.019 undersize clearances, this kit provides the reliability and performance you demand.
