MINI R55 to R61 Main Bearing Set - +.25 Size

The MINI R55 to R61 Main Bearing Set - +.25 Size is engineered for superior performance and reliability. Constructed from high tensile strength steel alloy, these bearings enhance rod bearing strength and retention. The increased crush improves bearing retention by enhancing radial contact pressures and heat dissipation. Bearing eccentricity is optimized to compensate for bore distortion and supports the formation of a hydrodynamic oil film, ensuring smooth engine operation. This set is +.25 size over standard, offering a precise fit for your MINI.

• Increased Strength: Higher tensile strength steel alloy for improved bearing durability.
• Enhanced Retention: Greater crush for better bearing retention and heat dissipation.
• Optimized Eccentricity: Compensates for bore distortion and supports hydrodynamic oil film formation.
• Precise Fit: +.25 size over standard for a perfect fit in your MINI.
