    Default Just ordered 3.54 rear end!!!

    I ordered a 3.54 rear end for my 85 L98. It should get me off the line a little quicker than my stock 2.73's.

    60 mph @ 2000 rpm , it should work well for me, my 85 I bought off ebay for next to nothin, I think I will keep adding crap to this vette and keep my 84 basically stock except for the renegade intake I am still waiting for.

    Mine works extremely well. Couple it with a good hole-shot converter (assuming an automatic) and it'd really limit your traction.

    Doesn't help my gas mileage any.

    Because they're made different? Nope... because they say Corvette on them? Nope. Because we just naturally have more disposable income? Well, some of us have more money than sense.

    Yes they are brand new with new seals and yoke thingys. It comes with that bat wing that people call it, not just the gears and the little housing but the whole thing.

    Because the gear set only fits a Corvette and not many people buy them.Supply and demand
    Millions of 9" Ford diffs fitted = bigger market , more buyers and cheaper production costs

    Well...kinda. The back half of the differential is unique to the Corvette, but the front is just a DANA 36 (or 44 in the case of the manuals). If a person was good a sealing the unit themselves, I'd imagine it'd be a little cheaper to not buy the whole assembly. That said, Corvette suspensions are VERY popular with the kit car/restomod community, which doesn't help availability.

    Wrong ,
    the D44 (D44-HD / Super 44 ) found in C4 Vettes ( and Vipers ) is unique to those cars.
    Has a D44 pinion with a D60 spline and D60 bearings.The Trac-Lok posi (carrier ) is also a one off .1/4" narrower than a regular D44 which is why you can't get an off the shelf D44 spool to fit a Vette.
    The C4 D44 is also different to the D44 (D44-ICA) found in C3's.Nothing interchanges

    You may be able to, but my 3.54 gears have my car turning 2400 rpm at 75 mph in 4th gear. It's hell on gas mileage.

    This plus a holeshot converter give me 1.9 sec 60 foot times on street tires, though.

    2400 at 75mph....hmmmmm...
    doesnt seem to high. unless you into long distance cruzin...
    but the 3:54's and yer input would answer a question..thanx..
    the only other experence i had was with a 6 spd. and a final drive of .5 with 4:10's...it was pretty sweet...
    but the final drive on the auto is .7 or pretty close to that so it would matter

    p.s.
    60 mph in 1.9
    seems like a desirable trait for a healthy corvette

    60 _feet_ not mph. Stock cars on street tires are close to 2.1-2.2 seconds
