    Front was not too bad. It's a little bit more time consuming than the rear diff. You just got to figure out a way how to wiggle the front diff out because one of the bolts towards the pinion side gets stuck in its housing. Plus these suckers are very heavy! other than that I have had no issues whatsoever. I am about to install the front today and will let you guys know how it goes.

    Looks great, what are the specs on the rims? Backspace, wheelspacers?

    Edit and I’m seriously considering 5.29 with 35 with a 17 v6 auto, any update?

    Oct 22nd I'm dropping my vehicle off to get 5.29 Nitro Gears.
    Running a manual transmission, 315/70R17s and have added weight from armor and accessories.

    I can't wait to see the difference!

    You're going to beat me to being the first 6MT with 5.29s! I see you're in AZ, who's doing your install?

    SDHQ. They will do REM polishing and speedometer caibrations. Expensive but I dont have to think about breaking in and figuring out how fast I'm actually going!

    Nothing so far but I need to trim the front bumper. Ultimately I’ll be getting a full replacement. It only rubs the front at the moment.

    Have you stuffed it? I feel like I'll need to trim the fender a lot so I can get full stuff without destroying the tires. I got a new plate bumper recently so I'm going to try to push my caster forward even more now for clearance from the pinch weld and CM.

    @JoeCOVA
    Can you share your thoughts on running 34s with 5.29?

    I am torn between 4.88 and 5.29 - I was really leaning towards going 35s, but I think 34s are the write size for me.
    Daily commute is 9 miles round trip on the streets.
    I have 28k on my truck in 18 months.
    Lots of long trips and monthly off-roading

    All right folks, I was able to put everything back together and have been driving it from last couple of days. I removed both 3rd members and got the gears cryo'd and got them set up from Rearend Specialties and assembled it back myself. So, my initial impression is that truck drives much better than before (had stock 3.90's). As @JoeCOVA mentioned truck shift gears much faster than before, which is actually a good thing. Truck pulls quite bit more than before in lower gears. I haven't pushed it hard yet because I am still in break in period. Took the truck through some small hills and truck didn't do the 3-4-5 dance and held the gear consistently. Another difference I noticed was that I didn't had to press the skinny pedal as farther as before. You hit the gas peddle a little bit and it will shift gears. My gas mileage has gone up, not that I cared. I use to get 12.5 mpg average and right now I am at 13.8. I am sure it will get even better after the break in period since I won't be driving around with 4x4 engaged.

    Before switching to 5.29's, I was thinking about going with 4.88's due to RPM's on freeway. Turns out that I was wrong. As OP mentioned, turd gens have 2 overdrive gears and that is when 5.29's really shine. At 65 MPH my RPM's were at 2000 and I think that is a perfect range. I was actually able to use and hold the 6th gear on a freeway. Please don't ask me what the RPM's will be at 80 MPH because I don't drive that fast lol. Anyone who is on the fence between 4.88's and 5.29's, I would highly recommend 5.29's due to all the stuff mentioned above especially if you have bigger tires lot of armor. As of right now, I don't see any cons of 5.29's, but if I find one, I will update this post.

    Little about the truck:
    -35x12.5x17 tires
    -Full skids including front, mid, transfer case, gas tank, and rear diff. All skids are steel, except gas tank I believe.
    -long bed full sliders with kick outs
    -OVTune

    Edit: 10/14/2018
    One of the forum members asked me if I could post a review of how 5.29's stack up on steep grades in 2wd vs stock gearing and if it still hunts for gears. One of the main reason I wanted to re-gear the truck was because when I was coming back from Yosemite, truck just kept shifting gears and hunting gears and I hated it and that is when I knew for sure I will be re-gearing.
    Even though I am still in break in period but took the truck on this one lane windy road near my house for 5 miles or so and elevation increases close to 1000 ft or so. I remember when I use to go on this road truck use to go crazy and use to shift up and down the whole time and RPM would range from 2K to 5K. WOW what a difference! Truck didn't hunt for gear at all and stayed in right gear and shifted ONLY when needed. I know this isn't a V8 and I damn wish it was, but for the first time I could say I was satisfied with trucks performance in hilly area.

    10/14/18 Update:

    So my wife and I just returned from a 2500ish mile camping trip of the Grand Circle which is probably one of the most amazing trips I have ever taken. I ended up running stock tires because the 35s were not completely balanced and due to a broken ARB compressor, I didn't get the new one until a day before we were leaving and had no time to wire it in. Without the compressor it would have been a challenging trip as beadlocks tend to leak a bit. Not to mention it I still have rubbing issues on the front bumper fender liner that I need to trim and the lack of wheel balance.

    Anyways the gears now have over 3000 miles on them and below is my fuel report which I will incorporate in the earlier posts but the total trip I averaged 18.8 which included some offroad trails in the National Parks to include Colorado River Overlook in Canyonlands (Moderate) and Tower Arch Offroad Trail in Arches (Difficult). Trailsoffroad lists these as 2-4 Easy but very few stock vehicles could make the Overlook and I was banging skids in Arches. The ratings I provided are my opinion and align with the "Guide to Moab, UT Backroads and 4-Wheel-Drive Trails."

    Fuel Efficiency:
    18.6, 16.5, 18.5, 21.3, 16.7, 20.5, 19, 18.9, 19.4 = 18.8 average and if you remove the offroading trips, I averaged about 19.4

    After having the gears with stock tires for so long and getting used to them as well as the transmission relearning everything I have to say that I am overly impressed with the gears and wouldn't consider any other gear ratio. After having so much success with the stock tires I almost wish I could go even lower for the 35s (assuming someone were to make them.)

    Honestly, I wouldn't even consider 4.88s after my experience with these, I find them so successful with stock that I know they will easily work with a 33 and 35. If anyone is on the fence about the gears I would honestly just go 5.29.

    My experience with the 35s is minimal because I'm still sorting out the tires and unfortunately winter is starting to settle in and we just had our first 20 degree day and I will be putting on snow tires in a couple of weeks. My wife and I frequently ski and run the high colorado passes and I know my Trepadors will be miserable on ice and snow so they will be getting stored for the winter and will probably come back out around March/April for the spring. I wish I had more data for the 35s but I hope I have provided enough on the stock tires for people to make an informed decision.

    I think @K_Sandhu has a great review with 35s which should help everyone as well.

    I don't have a ton of data on the 35s but I can say the <100 miles that I drove, the truck didn't even know they were there. Accelerated perfectly and drove fine but I never took it over 45 as the wheels need balanced and I have some extra trimming to do to the front fender liner. With winter coming they will be put away as I run a snow tire for the season.

    If you are on the fence I would go with 5.29, I don't think you will regret it at all; with 4.88 yo may find yourself wanting more.

    Wow almost 20mpg average for a huge road trip with varying terrain, nitro wasn’t kidding when they said these gears will get you good mpg. Excellent write up and your a hero for testing this out for us with stock tires.....new hunting shotgun will have to wait, gears are coming first!

    Definitely, I couldn't be happier. I think the sweet spot for fuel efficiency is around 45-65mph where the truck likes to sit in those overdrive gears. Under 40 you sometimes drop out of OD into 4th or 3rd depending on the road and over 65 you begin to have rpm creep where you lose a little bit of efficiency simply due to higher rpms. You start to lose mpgs under 40mph with the quick shifting of the AT, not sure how an MT would be affected by this if at all.

    Great write up @JoeCOVA and @K_Sandhu !

    Putting my pennies away for this. Just bought an aluminum cbi front bumper so I gotta replenish the fun money a little before I can pull the trigger. Excited!

    So I do have a MT, so i'm hoping it wont get me to much of a hit. I know you plan on going to 35's, but I'm running only running 31.6" tires, but full armor (steel sliders, and full skids), I think 5.29 may be the way to go now over 4.88.
