Lincoln Motorcars produced from mid to late 1928 through 1930 model L series, 1931 model K and 1932-1934 Model KA & KB used a straddle mounted ring and pinion gear set in the carís rear axle or more commonly referred to as the differential. The straddle mount differs from early model L Lincolnís by the use of a roller bearing at the tip of the pinion gear. The gears varied in sizes or ratios depending on the cars intended purposes and were available in four speeds: 4.23:1, 4.58:1, 4.90:1, and the lowest at 5.11:1. Limousines for example were likely to use the 5.11:1 ratio to allow the engine sufficient power to pull the extra weight. Roadsters almost always used the faster ratio of 4.23:1. Given the road conditions then, these ratios provided ample pulling power, climbing ability and moderate speed. The high speed ring & pinion ratio proposed is the 3.96:1. This will allow a moderate increase in speed for todayís highways without adversely affecting to a great extent the carís ability to climb hills. This 3.96:1 ratio gear set has recently been positively documented by Dr. Glenn Hamilton of Ohio over the earlier 3.77:1 gear sets manufactured in the 1970ís.



This is a solicitation for Lincoln owners for a group purchase to have a set of high speed ring and pinion gears manufactured. The single set price is $2,200, six orders, unit price is $1,750 and for twelve orders, unit price is $1550 each. Shipping in the US is approximately $30.
