    ST2DE5, sounds like "different strokes", plus there may be several variables with us. I drive Hawks, with 205/75 radials, on 6" wheels, which are about 27" tall. Not sure what yor drive, tire size, etc. I have ran gears from 4.27 to 2.39 in Studes, and in general, prefer final drive ratio below 3.0. This is easy to do with an overdrive, and is stock on many Studes, i.e. a 56J with T85 OD transmission & 3.92 rear end is 2.82 final drive, and the popular 3.73 rear end that came stock in many Stude V8s yields 2.61 in high gear OD. I once drove a GT around for a few thousand miles till I could find time to repair the OD, and was sure glad to get the OD back into operation. The straight 3.54 was noisier at road speed, ran hotter temps, and used more gas.

    Stude was limited to how low (numerically) they could gear the FlightO-O-Matic V8s, due to 2nd gear start. A TH350/400, with 1st gear start and 2.73 rear end will take off much quicker than a Flight-O-Matic with stock 3.31, and still have nice cruising gears.

    I don't know what your project is but I took out a 300-1 9 inch and put in a 275-1 made a trip about 250 miles and when I got back I put the 300-1 back in.

    According to several different carrier web listings...yes, it should fit fine.

    Hi, Joe,

    The 2.88 was original equipment on every Sunbeam Tiger. Not sure what else used them, but there are at least 7,000 out there. The Sunbeam Tiger Owners Association and the California Association of Tiger Owners are two places to look.

    Will work in US 44's with some bolt modifications.
    FWIW, we swapped out dozens of 2.88s for lower US Dana gears with no modifications. Your results may vary.

    Interesting as I was just looking at gear ratios for my 74 Avanti Dana.

    The 2.88's were European Dana ratios and used in Jaguars and some Sunbeams. Will work in US 44's with some bolt modifications. Although not sure why you would want them with other US ratios close.
