    Default where to buy new gear set up.

    I am looking to get a new gear set up. Most likely a 4.27 ratio since I'm running 33's and may upgrade to 35's some day. I have no idea what brands are the best and which ones I should get. Also would it be worth my time to get a whole new dif? I wouldn't mind having a locker. Thanks

    I saw a couple of recommendations on this site but will be intersted in seeing more opinions, as I am looking around myself.

    We always used PrecisionGears form RiederRacing. Installed hundreds of these gears and never had a issue, there great. Also If I remmeber right ARB has a air locker that fits your stock 2500 rear end.

    Thanks. How exactly does an air locker work?

    You have a small compresser usually mounted under the hood and a air line runs back to the rear end. When you what to lock the rear you just push a button mounted in the cab and it locks the rear. When your done off-road you push the button and it unlocks for street use. Best of both worlds.

    I forgot, ARB has a front locker for 2500's also. So when your off-road you can lock f&r axles.

    Alright awesome thanks for the help. I have an air compressor already for my train horn set up. You think that will work if I were to get the air locker? Also couple more questions ha. You think a 4.27 setup sounds alright? and if I were to get a ring and pinion kit could I install it myself?

    If I remmember they don't make 4.27's for your truck. Have to go with 4.10's or 4.56's. If your going to run 33's than 4.10's, run 35's than 4.56's. Can't tell you for sure about the t/horn compresser, I would think it would work. Setting up axle gear sets is a art in itself. If you have never set up gear sets than it can be VERY EXPENSIVE. Talk to some local people or ask the gear companies if they have some local recommended shops. Take your time and do your homework.

    Thanks for all the help. Yeah like hundojoe said I may go ahead with the 4.56 since I may get 35's one day. I do a lot of long highway driving back and forth from college so will 4.56 make it harder on my truck if the rpm's are a little higher?
