Master Chief ('22 Sport S Max Tow Sarge Green)

[metalry101]

Love your build! Seems like our rigs are pretty similar in a lot of ways. I'm very jealous of your 5.13s!

Santa came to my house early. Got the Rock Krawler rear triangulated system for Black Friday and saved 20%. I got the lower arms to go with it. I'm excited to get it installed soon and see how much it improves the ride. I was impressed with the quick delivery, and the packaging was pretty good too. No instructions, but thanks to Northridge 4x4 and Quadratec along with a couple others there's some good videos that explain the install.

@Rock Krawler Suspension rear arms installed over the weekend. I love the difference in how the jeep rides now. No more cross talk in the rear track bar, floats over some train tracks in my neighborhood that use to make the truck shimmy sideways. Another benefit is this kit also fixes the stupid pinion dropping while flexing problem.

Some things I learned that I didn't know from my research...
1-You will need new rear brake lines. This kit gave me way more flex than the Mopar lift and the brake lines were tight. I think they were the limiting factor when doing the install not my shocks. I ended up installed a DOT set from Currie.
2-Extend those abs lines while you're at it.
3-The rear sway bar extensions from the Mopar lift are also not long enough, they need another inch or two, there is a possibility that they could flip backwards while on the trail.
4-I'm going to need spring retainers, this flexes so much that I could possibly drop a rear spring at full flex. With the axle hanging from the shocks and brake lines the springs were slightly loose.
5-Most important, make sure you find an alignment shop that understands how this suspension works and making sure the axles are centered and square to the Jeep. I'm lucky enough to have a good 4wheel drive shop here in Utah that can do this and understands triangulated suspensions.

Scariest part for me was drilling the holes in the housing and tapping them. Everything worked great and RK provided everything to do it. Although make sure to use cutting oil, I didn't on the first whole and it made the drill bit dull, nothing I couldn't fix with a sharpening, but when I used cutting oil it made it a lot easier.

Looking forward to getting this on a trail and seeing how it does.

I'm pretty new to posting, but I've been around lurking while I've been learning and building my ride. I do most things on a tight budget, and find deals as much as possible. Some things I trade my metal fabrication skills for, some things I just know good people and get things cheap or free.

What I've got and why
2022 JTMT I ordered and got almost everything I wanted. (Only thing I wish I would have done is order the half doors with it) My son calls it Master Chief (from Halo) and the name has just kinda stuck. I ordered the Max Tow model because I pull a recreational trailer around the mountains/deserts of Utah/Idaho/Colorado/Oregon and anywhere else in the spring/summer/fall and didn't want to deal with DEF in the diesel.

Lift / Suspension
2" Mopar Springs, CORE 4x4 front control arms, Rock Krawler rear 4 link triangulation, and Mopar rear sway bar links
Apex Designs Autolynx Sway bar disconnects
Steersmarts Yeti XD pro front track bar
Sumo Springs bump stops front and rear with DIY lower bump stop extensions (made the ride so nice on the bumps/rocks)
Fox 2.5" body shocks

Wheel / Tire
KMC Dirty Harry Bronze with +18mm offset. The wide track axles allow this offset and no rubbing.
BFG KO2 - 315/70 R17

Accessories / Modifications
Cobra 75 All-Road CB radio
Midland MXT575 MicroMobile® GMRS 50-Watt Two-Way Radio
APEX Designs steering upgrade and cooler
ARB twin compressor mounted in the bed of the truck, wired to the Jeep aux switches. Airline comes out in the rear bumper opening so I don't have to open the bed to use it
Rugged Ridge Venator front bumper
Smittybilt Gen 3 XRC 9500 lbs winch with synthetic rope
Rubicon rear axle swap with elocker, wired to the Jeep aux switches with Mopar wiring harness
Dana Spicer 5.13 gears - yes they are "low" with the 315/70r17's, but it's amazing pulling my trailer, and amazing on the trails
Dana Spicer chromoly rear axle shafts for the Rubicon axle housing (Learned that even though the housing is the same width the shafts are different widths than the Max Tow shafts do to the elocker center pin being off center)
Teraflex heavy duty diff covers front and rear
JScan unit to set tire size / gears... Don't need all the extra stuff in the Taser
Bestop granite series bed sliders
Bestop granite series front inner wheel wells
CMM Offroad side mirrors for doors off days

Future
New set of shocks, haven't decided on the brand yet. Falcon, King, Bilstein, OME, Fox, I don't know?
Steering Stabilizer, also haven't decided on brand for this either
Steersmarts steering sector shaft brace
Steersmarts high steer kit
Chromoly front axle shafts and FAD eliminator
Probably some off-road lights for when I get in the desert late with the trailer to find spots to camp and I have 2 more aux switches that I need to use
I think I want the Method bead grip wheels.
37" tires, probably BFG's I've had great luck with them

Any issues with the allroad 75? I just did a warranty claim on mine as it would not like to transmit or receive but then work intermittently. I would try to reset, use Bluetooth, use direct connect, recheck antenna install (grounds ect) and the swr is always below 2

I haven't had any issues it's been good so far but I'm changing over to the Midland GMRS MXT575 radio as most everyone I go with has moved over to GMRS. I'll keep the Allroad around if I ever need it but the trend seems to be GMRS or HAM where I"m at.

I only have cb because my dad refuses to modernize lol but I also use the Midland when I'm not with my old man. He got me the 75 as a gift so ya

Well after just over 52,000 miles it's time to change out the tires. I went from the BFG KO2, which was a great tire until the end. It got pulled all over the road and wouldn't keep a balance. The new tires... Mickey Thompson Baja Boss AT. I've read a lot of really good things about this tire in the different weather conditions, and have a couple friends that love them on their Jeeps. So a new set of 37x12.5r17 tires and the Jeep is good as new. I felt like it would look bigger, but not much changed. Guess next time I need to jump to a 40" tire. lol.
