Bentley MkVI R Type Continental Crown Wheel & Pinion Set RG7455A

Part number RG7455A is the genuine 13:40 crown wheel and pinion set for Bentley MkVI, R Type, R Type Continental and Rolls-Royce Silver Dawn models. It provides a 3.076:1 ratio for the specified rear axle applications.

The 13:40 ratio was the standard ratio used in the Bentley R Type Continental Sports Saloon. It provides just under an 18% gearing increase over a standard Bentley MkVI axle and nearly 10% over the last Bentley R Type production axle.

With standard 6.50 x 16 tires, the 3.076:1 ratio provides approximately 55 mph at 2,000 rpm and 69 mph at 2,500 rpm. This gearing is suitable for both short and long-distance touring in the specified Bentley and Rolls-Royce models.

The crown wheel and pinion determine the final drive ratio of the differential and influence the relationship between engine speed and road speed. Correct installation and differential setup are essential for proper rear axle operation.

Please verify the axle application and part number before ordering to ensure correct fitment. Professional installation using the appropriate specialist tools and procedures is recommended when servicing the differential and rear axle.
