    Rear gears

    Hey guys, I have a stock 2000 Firehawk Conv with a 6 speed and auburn differential. I'm going to change my gearing to either 373 or 410. Looking for recomendations, not a daily driver but more of a once a week to work kind of car. Thanks.

    I guess it will be 410's, thanks for the offer on the Richmond gears but I'll be pursuing the warranty issue.

    I went with 3.73s for two reasons - less prone to noise and better gearing for 65 -70mph cruising. 6th becomes a usable gear as an added bonus.

    With 4.10's, you might be running into a noise issue. Make sure you work with a competent installer. I'd recommend Motive Performance gears (or AAM), since they're generally acknowledged to be pretty quiet.
