  • Need set of 3.73 or 4.10 gear for 10 bolt.

    Looking for a 3.73 or 4.10 gear set for a 7.5" 10 bolt rear end. My became damaged due to sniper performance messing my car up

    i had 3.73's twice now and both time exploded. friends talked me into 3.42's. said 10 bolts are not good with bigger gears. specialy if built. just passing along some of my bad luck once again a wk ago.

      I've had my 3.73's in for 4 years now and haven't had a problem with them. Car is an A4 though. Got them put in at DTS in Warren.
      When in doubt, Whip it out !

          I just build my 10 bolt with a Detroit Trutrac posi and motive performance 3.73 gears. Seems okay now, but still haven't put any miles on 'em.

          Honestly I'd go with new gears. For the price, it just isn't really worth screwing around with used gears. If you're going to take the time and set 'em up, I'd only want to setup new gears.

            Just went out and looked and found my old 3.73 gears. Its a used GM set from a 7.5 10 bolt that i got. Rear was noisy from bad bearings which is why i rebuilt it. Carrier was also bad so can't say for sure if these gears are any good. Lmk if you're interested.

            I also have a set i was told was 4.10 I got second hand. Not sure if its any good. On an open carrier and has pinion bearings no races. I dont really wanna sell but can if you really want
