      Your answers are conflicting. In one you say that both carriers will need to be replaced and another says only the front if running original 3.21 gears. Can you please clarify this discrepancy for use on my 2008 JK Sport before I purchase these?

      • It would depend on what factory gears you have as there were 3 stock options- 3.21s, 3.73s and 4.10s. If your 2008 JK sport came with 3.73s or 4.10s you would not need to replace the front carrier. If you have 3.21 gears you will need to replace the front carrier.

      I have a 3.21 gear ration now and want to get this, however, I would need a new carrier - where can I find one that fits my 2011 Jeep Wrangler JK and will work perfectly with this Revolution product?

      • In order to install the Revolution Gear & Axle Dana 30F/44R Ring Gear and Pinion Kit w/ Master Overhaul Kit you will need front and rear carriers designed for 3.73 and up A full list of differentials are linked below:

      It is my understanding that the kit includes everything for install of these gears, but another question asked if a new front carrier is included , and no was the answer. i was under the impression that a different carrier was needed(3.73or bigger) to install these gears in the front ? does this kit need an additional larger front carrier to work in my 2013 wrangler 4 dr or will theses fit as is in my front axle?

      • The Revolution Gear & Axle Dana 30F/44R Ring Gear and Pinion Kit w/ Master Overhaul Kit - 4.56 Gears will not include a front carrier, as a new front carrier is only needed when your Jeep cam stock with 3.21 gears. 3.21, 3.73 and 4.10s were stock gear options, if your Jeep came with 3.73s or 4.10s a new carrier would not be required. If you are unsure what stock gear ratio you have, please contact us directly and we can help you determine your ratio. Our contact information can be found here:

          Switched from stock with my 35s and you can tell the difference. Really worth it.

          Great Gears for Regearing

          Packaging was great and came with everything I needed to complete the regear. I wouldn't attempt the regear myself if I didn't have the correct tools - this kit doesn't come with tools.

          Gears chewed up like bubble gum

          These gears failed on me and the gear company did not want to warranty them it happened with in warranty time. Buyer beware.
