ACL Race Series CT-1 Coated Main Bearings (0.025 Oversize)

For engine builders tackling a crankshaft grind, the ACL Race Series 0.025 Oversized Main Bearing Set provides the perfect fit for your Subaru EJ20, EJ22, or EJ25. These bearings feature the advanced CT-1 coating, which offers superior dry-film lubrication and protection during critical startup phases and high-load scenarios.

Why Choose CT-1 Coated Bearings?

• CT-1 Coating: Advanced surface treatment reduces friction and improves heat dissipation.
• 0.025 Oversize: Engineered for precision-machined crankshafts requiring additional clearance.
• #5 Thrust Compatibility: Designed specifically for Subaru blocks with the #5 thrust position.
• Race-Proven Material: High-strength tri-metal construction for maximum load-bearing capacity.
• Improved Oil Retention: Optimized surface finish promotes consistent oil film stability.

The CT-1 coating acts as a sacrificial layer that protects the bearing surface from scuffing and seizure. This is particularly beneficial for high-boost turbo applications or track-focused builds where oil temperatures can fluctuate rapidly. Whether you are building a street-legal powerhouse or a dedicated race machine, these oversized bearings ensure that your rotating assembly remains protected under the most demanding conditions. Ensure your crankshaft is measured accurately by a professional machine shop to match these 0.025 oversized shells. Elevate your engine's longevity with premium parts from GGCRACING.
