    So you're planning to ditch the IRS? Are you keeping the front IFS? What's the application for this build?

    HUMVEE Ultra4 (KOH) Build?

    No exciting updates yet. I've been trying to work through some projects to make room for this one. I've done a little measuring on the body. The narrowing is going to be a very interesting task, but I'm anxious to start cutting. How dangerous is the CARC paint? With all the cutting...

    CO Supercharged IFS Ultra4 Race Car - 1100hp

    Hopefully it's ok to post this here. It's not a military vehicle, but its sale will support a Humvee build!

    CO Supercharged IFS Ultra4 Race Car - 1100hp

    This is the Fastest & Highest HP Ultra4 Car EVER! Obviously this is a loaded statement, but this procharged IFS 4400 car puts down 740hp to the rear wheels on a chassis dyno in full competition trim w/ 38" tires. At the dragstrip it has run a 10.2 sec 1/4mi @ 135mph with a 9200' Density...

    HUMVEE Ultra4 (KOH) Build?

    Got a few parts together this week: -Built 4l80e -Billet converter -Winters gated shifter -LS3 (Ive had this guy for a little bit, trying to decide if I want to stroke it out to a 415 - which I already have a crankshaft for, or leave the bottom end basically stock) -40 gallon fuel cell and pump...

    HUMVEE Ultra4 (KOH) Build?

    I did see their site. Thanks for the recommendation. Neat stuff, but more than I care to spend. At that price I'd prefer to build my own. Especially because it looks like I'd need to modify their design to accommodate the coil over and bypass shock configuration I'm planning. But, it might...

    HUMVEE Ultra4 (KOH) Build?

    Thanks for all the feedback guys! I would like to build this so it could compete in either 4500 or 4400 classes with just a shock & tire change. 4500 is stock modified which limits tires to 37's and shock diameter to 2.5" (also requires resemblance to a production vehicle and a mechanical...

    HUMVEE Ultra4 (KOH) Build?

    Hey guys, Not sure if anyone here is familiar with Ultra4 racing, but this is an offroad race series that combines high speed desert or short course with rock crawling. The most famous race in the series is King Of the Hammers (KOH). I've been racing in Ultra4 since 2012. I started with a...

    Soften M1123 suspension

    I've been using 2008. Not sure the exact year range, but that works great. Just so it's clear on ride height: with a stamped steel mount you'll most likely want cut somewhere around 1-1.5 coils and with a cast mount you'll want a small spacer with a full length coil (I'm using 1/2").

    Soften M1123 suspension

    Define "Don't work". I ran the ram springs in my last HMMWV and they worked fine. Yes, there are a number of different rates. I wouldn't really recommend them as they're not a great fit, but they worked and rode very nicely, just don't fit as well as the Aramada's. My current M1123 HMMWV I'm...

    Gauge brackets idea.

    Nice job! Here's what I've used: AutoMeter 2225 AutoMeter Gauge Mounting Brackets | Summit Racing Just need to trim to length and grind a little for clearance (depending on which gauge you use it on).

    Installing the H1 Rocker Panel Protection on Hmmwv

    I've installed them. You need a spacer between them and the floor. Forgot exactly how thick. I also like to add some side bolts. Slap them up there and drill some holes! :p

    Dongfeng doors on Humvee

    Where do you buy the Dongfeng doors from? Do you know for sure they'll fit a Humvee? I 100% agree about the prices. I wish a company like bestop would jump on the HMMWV market and make some reasonably priced doors & tops. I don't see why the same part for a jeep needs to cost 5 times as much...

    Hemi 5.7L Engine Swap In a Hmmwv

    I run a 6.1 Hemi in my 4wd offroad race car. The engines are great, but the dodge electronics/control system is a nightmare. After lots of time and money and a number of races lost because of issues, I finally gave up on running the computer controlled trans and went with a Holley Terminator...

    Torsen differential locking tips and tricks

    I don't have the ability to see your video right now, but I'll make a couple comments. BTM is best used in Low-lock. This will provide the most torque to overcome the applied brake resistance. You can use it in High-lock (or even high), but if your conquering an obstacle requiring...
