Clevite Tri-Armor Coated Connecting Rod Bearing Set for GMC V8 Engines

Engine rebuilds demand components that handle intense demands without compromise, and the Clevite stands out as the reliable solution for GMC owners seeking consistent performance in their passenger cars and trucks. This H-Series bearing set delivers strong load-bearing capacity up to 12,000 PSI, thanks to its proven three-layer TriMetal design featuring a babbitt overlay for embeddability, a copper-lead alloy interlayer for fatigue resistance, and a precision steel backing for structural integrity. The exclusive Tri-Armor coating, a low-friction PTFE polymer infused with moly and graphite, minimizes drag during startup and operation, ensuring smoother rotation and reduced wear even in high-revving or heavy-duty applications. For GMC enthusiasts rebuilding classic V8 powerplants or modern LS swaps, this set provides the dependable foundation that keeps engines running stronger longer, making it the clear pick for anyone prioritizing longevity and efficiency over generic alternatives.

  • Size: Standard undersize (STD) for direct replacement without machining.
  • Coating: Full Tri-Armor dry film treatment on both sides for all-around protection.

  • Part Number: CB663HNC
  • UPC: 639789291271
