My cummins monster/mega mud race truck build.

This has been a slow project, but will be done this year. These trucks are referred to as “mega trucks” by many, but basically a monster truck with tractor tires for playing or completion racing. Feel free to ask questions, depending on how soon I get it ready to fire, I will either be building a budget motor or pulling the motor from my 2006 1000hp driver/play truck.

Here’s some stats... I built the frame from scratch in my attatched garage. I started with a school bus 12 valve and Alison, and quickly changed my mind and went to a 2005 common rail with a 3 speed 727. Josh at Jag’s Pro Truck Shop in zimmerman showed interest, and was nice enough to sponsor me a painless wiring harness that he setup for me to Eliminate a lot of wiring, Repinned for a 2006 cummins ecm, and move the ecm to the cab. Josh also set me up with an old “baby” set of 200% over injectors to fuel the beast lol. The transfer case is a revered rotation quick change full billet. The axles are 5 ton rated top load military, which I allready feel I’m going to change out. The suspension is double triangulated 4-link with 26” travel full nitrogen shocks. The body is a 4th gen ram.

Well I have a ton of pictures, but they won’t load from my phone.

Love it!!!:rockwoot:

I’ll try to dig up more pictures off my Facebook and old phone. The tube is all 2” .120” thick. Every bracket, mount, and piece I designed and my friend plasma cut for me.
I have several turbos/combinations. I have an idea in my head what to try, but I’d love to run a super/turbo setup eventually for throttle response.
Im planning on running air to water cooler with heat exchanger and ice tank.
Tires are 14.9-24 which measure 50.5” tall. They’re the minimum “spec” size required for my class. I also have bigger sets for mudding and playing around, including 66x43x25 monster/terra gator tires. The rims are 24.5” aluminum Alcoa’s machined to 24”

From the time I drug it out of my garage until I started building the cage with a friend, it sat for almost 2 years waiting to get in a shop big enough. It’s also hard with my job and having a kid November 2016 that I spend all my free time with. But now I’m kicking butt and determined to get it done

Very kewl !!!:rockwoot:

I thought I seen this the other day on Facebook. Looks like a sweet build

This is killer. Cant wait to see the finished product.

Good to see the progress on it Jake. Remind me again where you got the body from? How did you like the fit and finish?

“Brothers racing bodies” they have a Facebook page. Shawn builds these primarily for monster trucks, he has a few different models, but only dodge is a 2012 regular cab long box ram 1500. The body was only $1800 which I couldn’t even buy a smashed or blown up truck and part out for that price. The fit and finish is incredible. The only (possible)down fall for pullers Itsjust a shell, I’m cutting “doors” into the cab panels but typically monster trucks are a single center seat so they crawl in between the frame and rocker panel. I shortened the bed 15” and offset cut the wheel wells for a better “stance”

Be curious to see how that particular trans works out

I hated the early 518A, i gave it every chance with billet shafts, Houghs convertor etc....it just didnt apply well. TH400 was the way to go for me and they are just that much better today since Rossler has really got behind them and improved just about every asspect of the already super good trans. 2 spd or 3 spd, any ratios, massive inputs, SFI cases now like the glide always had, crazy strong brake, big bell housing for big lock up convertor, list goes on for sure

Comparing houghs to rossler is apples to oranges. I’m confident the 727 will be the right choice. I talked to a lot of big name shops that say it can be done, I’ll probably be dealing with Goerend and CRT when I build it. By the way, many racers are converting 48re’s to 3 speed and non lock up converters

It wasnt back in the day while i was doing it, Houges and Chance was the best back then, but neither could help me get a convertor thst would work, a Lot has changed since then. The fastest trucks in the country are running 400s now, lock ups. All i know is its a ****y long hard road when you choose the wrong gear box. I learned the extreme hard and expensivw way, advise is the only thing that free.
I started with the 727 and 518, then went to the Powerglide, then own to the th350 ( which is a joke of a trans, by far the weakest of the bunch i tried). Then the th400. I went 1.09 60' 5 flat in the 1/8th and 8.20s 1/4 with a non lock up 400 behind a mild 12v, less than 1k hp probably. With 36" slicks and 3.40 rear gear.
Not telling you your business just offered free advise is all. Best of luck to you with the project
