ACL Race rod bearings for Mitsubishi 4B11

ACL Race trimetal rod bearings are designed for demanding operating conditions at high RPM. Their construction combines a high-strength overlay, steel backing and engineered bearing geometry.

The set is intended to improve bearing lining support, bearing retention in the housing and the formation of a hydrodynamic oil film. It is available in different sizes depending on the selected variation.

• High-strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backs on the rod bearings to improve bearing lining support
• Increased crush for improved bearing retention in the housing
• Elimination of flash plating on the back for improved heat transfer and grip in the housing
• Increased eccentricity to compensate for bore distortion at high RPM
• Tight, consistent wall tolerances to help maintain consistent clearances

Suitable for: Mitsubishi Lancer VIII (CY/A).

Engines: 4B11 (4B11-T). Please check your vehicle’s engine code (registration document or VIN) before ordering; if in doubt, contact us and we will check for you.

Sizes

STD is the standard size for an unground crankshaft. Undersizes (−0.25 mm, −0.50 mm …) are for a reground crank, and “+0.025 mm clearance” (X) is for highly stressed engines. Your machine shop chooses the size after measuring.
