3.73:1 ratio 8.8" Rear Ring and Pinion Set

The 3.73 ratio is in our opinion the best overall ratio for all the automatic transmission cars. It will be great on the street and highway and it offers terrific grunt off the line at the strip.

This ratio was never factory installed. We highly recommend the 3.73 ratio or you may want to consider the 4.10 ratio if you are looking to be aggressive in the stop light wars.

Owners of cars with the 4R70W electronically controlled transmission should be aware that using this ratio will hasten transmission tailshaft bushing wear due to much higher output shaft RPM. You should consider getting a forced lube kit from us to lube this bushing and solve this problem. Also, electronically controlled transmission cars will require a chip to reprogram the cars so it shifts properly. SCP offers these also.
