        5 2003 Wrangler - 1 Installation Time: Afternoon

        Good to go

        I replaced some Yukon gears in the front of my 2003 Wrangler TJ after my "mechanic" installed the other pinion incorrectly and damaged them. I have been very happy with these gears in the past on my other jeep (95 YJ). No issues with these so far because they've only been installed a couple of days. We in fairly easy with no problems. Everything bolted in without issue and seem to be working perfectly. Went to the beach the day after the install, ran around on the beach all day with no issues. Would recommend them to anyone needing gears, whether to upgrade or replace damaged/broken gears.They wouldve probably went in easier but I had to replace everything to to improper installation by another shop.

        G2 ring and pinion

        Ordered G2 ring and pinion and install kit for Dana 30 in 2001 TJ. Parts fit fine. Only issue was neither gears or install kit came with instructions. Also ordered Yukon gears and install kit for 8.8 in the rear from another supplier and each came with install instructions. Other than no instructions the product is fine, still in the process of breaking in the gears so time will tell.

        g2 gears

        I have gone threw 4 axles now weather it was a bent tube or exploding spider hears reaking havoc on the case, cracked case but I have never chipped or broken a tooth off these gears or pinion. Had a chip on the pinion but nothing a little emery cloth and time couldnt fix would def recommend getting the master install kit when you in there replaceing gears why not do the seals and the bearing try to make the 30 as strong as you can till you can upgrade to 44s or larger.

      Sorry for this in advance, but If I search for G2 Dana 44 Ring Gear and Pinion Kit - 4.10 (97-06 Wrangler TJ) the D30 comes up. Could you tell me if you are just sold out of the 44 - or possibly point me in the right direction to finding a G2 D44 Ring/Pinion geared at 4.10. Frankly it's been a nightmare finding this part. My rear axle has an ARB locker, the 4.10 is what we pulled out but so far our search is coming up short locating a replacement. I push 33"s and really the driving lately has been light, Im surprised to see the Ring and Pinion go. I'd like to go G2 but at this point anythings better than nothing! Thanks in advance for any advice or insight you may have! I appreciate it!

      • At this time G2 does not make a matching Dana 44 Ring Gear and Pinion Kit in 4.10, Per their product catalog, only 4.09 and 4.11 options are offered. At this time the only offering we carry is the Alloy USA kit linked below:
