Driveline & Transmission

The 3.55 ratio should be considered aggressive for the '89-95 supercharged manual transmission cars. If you do a lot of drag racing or rarely hit the highway with your car you may want to consider this ratio for this application.

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.

The 4.10 ratio should be considered an aggressive street/strip gear for the automatic transmission cars. If you do a lot of drag racing or are looking for terrific throttle response on the highway with your car you should consider this ratio.
