does this unit work for 3.73 gears?

 

Yes 3.36 3.55 3.73 3.90 4.10 4.33 4.56 4.88

What rear has 3.73 that your working on? Pontiac Oldsmobile and Buick do not offer 3.73 from the factory...We do have aftermarket 3.73 gears . Jim

 

The rear I currently have has 3.08 gears. I was told that I new to upgrade the gears so it could cruise better. The rear end axle tubing decides that it's a 70 8.2 Chevy.
