Clevite77 H-Series X-Clearance Narrowed Coated Rod Bearings for Small Block Chevy

Maximize oil flow and enhance durability in your Small Block Chevy engine with the Clevite77 H-Series X-Clearance Narrowed Coated Rod Bearings. These standard size bearings are engineered with an "X" (extra) oil clearance, providing a larger oil film for engines running higher oil temperatures or requiring increased lubrication. The narrowed profile ensures proper fitment with crankshafts featuring larger fillets, while the advanced coating offers superior friction reduction and wear protection under the most demanding conditions.

Optimized Lubrication for Extreme SBC Builds

The combination of extra oil clearance, a narrowed design, and a durable coating makes these Clevite77 bearings ideal for heavily modified or race-spec Small Block Chevy engines. The increased oil film helps dissipate heat more effectively and provides a stronger hydrodynamic wedge, crucial for preventing bearing failure at high RPMs and heavy loads. Trust Clevite77 to deliver the precision and protection your high-performance SBC demands.

Key Features:

  • Extra Oil Clearance (X): Provides a larger oil film for enhanced lubrication and heat dissipation.
  • Narrowed Profile: Ensures proper fitment with crankshafts featuring larger fillet radii.
  • Coated Surface: Advanced coating reduces friction and wear, extending bearing life.
  • H-Series Construction: Designed for extreme performance and racing applications.
  • Standard Size: Suitable for crankshafts maintaining factory dimensions.
  • Small Block Chevy Specific: Precision-engineered for SBC engines.

Vehicle Fitment:

These Clevite77 H-Series X-Clearance Narrowed Coated Connecting Rod Bearings are specifically engineered for Small Block Chevy (SBC) engines. They are highly recommended for race engines, forced induction applications, or any high-performance build where increased oil clearance and a narrowed bearing profile are critical for optimal lubrication and reliability. Always verify your engine's precise needs for perfect compatibility.

Why Choose Clevite77 X-Clearance Narrowed?

For the most aggressive Small Block Chevy builds, standard bearings simply won't suffice. Clevite77's H-Series X-Clearance Narrowed Coated Rod Bearings offer a specialized solution, combining superior oiling characteristics with advanced wear protection and precise fitment. This ensures maximum engine longevity and consistent power delivery, even under the most brutal conditions. Elevate your engine's performance with components from GGCRACING.
