Speedway MaxLite Differential Ring and Pinion, Ford 9 Inch

Reduce rotating weight with Speedway's MaxLite Ford 9" Ring & Pinion Sets. We start with the Richmond Gear EXCel Series Ring & Pinion and machine off the unwanted rotating mass in our machine shop in Lincoln, Nebraska. Available in ratios ranging from 3.50 all the way to a screaming 7.00 (and everything in between—3.70, 3.89, 4.11, 4.56, 4.71, 4.86, 5.00, 5.14, 5.29, 5.43, 5.67, 5.83, 6.00, 6.20, 6.29, 6.33, 6.50)

• Reduces spin-up time to max RPM as well as rotating weight
• Can lighten up to 4.56lbs depending on ratio
• Machined in house at Speedway Motors

Note:  Circle track racing applications require a minimum of 4 qts. of rear end lube.  Using less than this amount will lead to immediate pinion bearing failure.
