Gear Vendors overdrive

I have one in my Duster

30" tall rear tire...4:30 rear...75mph @ 2400 rpm, the sweet spot!

I see used ones less than $1500 from time to time

I would buy one again. I slightly modified the tunnel to get it to fit as high as I wanted to keep the pinion angle on my rear end realistic.

FYI....it is NOT a soft shift....you now when it hits
