Starting a thread here to share the stories of my racing effort. I have been following along on a lot of the other team’s threads both here and on the old site. All of those were big inspirations for me to get into racing. Hopefully sharing my story inspires more people to start racing.

I was also not great about taking pictures during the build process. I hope that starting and maintaining a thread gets me to be better about pictures while making improvements/changes.

A little back story, my first car in high school was a 1998 Wrangler. Despite none of my family members being into wheeling I started exploring and wheeling in the front range of Colorado.

Sometime in high school I stumbled upon an early King of Hammers race that had been uploaded to YouTube, and the idea was planted that I want to race it someday. I continued wheeling into college with both a Land Rover LR3 and then a 2004 Rubicon. Through my college’s 4WD club I made a few friends with people that also followed Ultra 4 and had desire to go race.

I graduated college in 2015 with a degree in Petroleum Engineering. To find a job during an oil bust I had to move down to Houston Texas.

In the fall of 2016 made the decision to buy a chassis and start racing. At the time I had just moved from Houston to Midland, TX and was living in an apartment with my girlfriend. Emailed back and forth with a few builders looking to purchase a rolling chassis. The though was that a rolling chassis would be the quickest/ cheapest way to start racing. It would also force myself and the team to have an intimate knowledge of our car as we will have put all the finishing touches on the car and by the end of the build have taken it apart and re-assembled multiple times. In hindsight this route was definitely not the cheapest but has made troubleshooting and improving much easier as myself and the team are very familiar with the car.

By the winter of 2016, I ended up deciding on a rolling chassis from Jimmy’s 4x4. At the time Vaughn’s Brocky build was just released and being a ford guy I also wanted to have the classic bronco skins. Randy also hooked me up with a good deal on some used parts to keep the cost under control. Fun fact, the rear torque 14 axle was used in one of the car Top Gear used while filming about King of the Hammers!

The plan for the build:

Jimmy’s Chassis with Bronco skins
Rock Jock 70 front axle
Torque 14 rear axle
351W based engine
TH400
Atlas transfer case
32 Gal Jaz
3.0” King IBP Coil Overs
PSC Steering
CBR Radiators/Cooling

In July of 2017 I took delivery of the rolling chassis and a bunch of parts from Jimmy’s 4x4. Being in an apartment in Midland I somehow talked my parents into letting me build the car in their garage up in Denver, CO.

The only issue was the commute from Midland to Denver. Progress was slow as I was only able to make the trip up on long weekends.

In October 2017 I purchased an old 351W for mockup, and ordered a new 427 stroker from Ford Stroker.com.

Then I got to work trying to figure out seats. After a bunch of reading, I decided to go with a composite shell seat and picked the Mono Daytona XL and it was the only one I could correctly fit in. One bonus was, I thought, also the most comfortable. My co-driver picked out an OMP seat. Got both mounted with brackets that allowed the seats to be swapped side to side. Moved to Houston, started flying back and forth on long weekends.

In March of 2018 the new motor arrived!

In January of 2019 I finally bought a house in Houston and was able to move the car into the 2-car garage in the same house I was living in!

Side note while road tripping a 87 YJ from Denver to Houston I had the timing chain sprocket loose a few teeth.

Progress started to pick up.
Got a set of custom headers made by GPHEADERS INC. Mockup pictures:

My co-driver started designing the wiring for the car. He talked me into doing a fully sealed harness, even though neither of us had any experience putting one together.

Got married to my girlfriend in June of 2021.
In July of 2021 Completely torn the car down and took the chassis to be blasted and painted with Steel-It.

April 2022 took the car to Rally Ready near Austin, Tx for its first test drive other than around the block.

First Race was at Vision’s Oklahoma in July of 2022. We came in 17th of 28 in the EMC race improving our position from qualifying 25th of 31. The whole team came together Friday night to fix both an overheating problem and a crack in the oil pan that developed during the qualifying run. I definitely had some rookie mistakes during both the qualifying run and on race day. The team and I learned a lot and we will be making a few tweaks to the car, our race strategy, and pit equipment to get ready for King of the Hammers in 2023.

Great build.

I’m interested in seeing more on your swap-able seat mounts.
 
The biggest take away from Visions was the need to get the shocks tuned!

Got on schedule with Ryan at AccuTune for a tuning session. But with no major repairs needed I took the time to paint the panels. Went with Euro Racing Green from Eastwood as hunter green is the wife’s favorite.

I’m interested in seeing more on your swap-able seat mounts.

Both the driver and passenger side of the car have almost identical tubes welded in.

Screenshot 2025-01-07 144333.png

Each of these tubes have a provision for 2 1/2" bolts to hold the seat mounts in place.
Screenshot 2025-01-07 144443.png

The seats then slide down between the two tubes and are held in place by the four bolts.

We ended up having to do it this way to get the bottom of my seat low enough in the chassis to have adequate headroom for me (I am 6'3"). If we went with the off the shelf brackets mounting from below the the seat the driver drop transfer case would push the bars/seat too high. Right now there is may a 1/4 gap between the bottom of my seat and the floorboard underneath it, then ~1/8" to the top of the trans case.

Decided to mount the belts off the bracket as well. By doing this we are able to swap seats side to side and the belts go with the seat. Which is nice since the Schroth seat belts (SFI 16.6 Formula II) that I am running have only one pull up adjuster on the lap belt.

More pictures of another set I just made:

That's a great color!!!
 
Here is a random pass from the day spent shock tuning in JV:


I think the time, money, and effort spent tuning shocks was the best MPH/$ spent ratio of the entire build/ tuning process on my car!

On a very round about way home from John Valley we stopped in Moab to do some trail wheeling. Ran through Hells Revenge in the morning. Then headed over to Rear Steer to do some rock crawling. Rear Steer really challenged both my driving, the car, my co-drivers patience, and the winch.
**I have a go-pro video of this attempt, but its pretty boring as its mostly just looking a bunch of rocks while my co driver pull winch line....:lmao:
 
The next outing was the 2023 King of the Hammers. Early in the week we fought coolant leaks, random fuel pressure losses, and a windstorm. But the team pulled through and we had some great times pre-running the race course. By qualifying on Tuesday, we had the car working great and were feeling confident!

On Tuesday morning we got out to Chocolate Thunder early and got to enjoy watching some 4600 and a few 4800 cars before jumping in and buckling up. Our run up Chocolate Thunder was clean; the left line treated us well and we were through without much drama. We bombed across the ridge, down Laser Nut Alley with no issues. However, at 3 minutes and 18 seconds into our run on the sandy climb the bypasses the rocks of Her Problem, the axle side bolt on the front driver side upper link broke, stopping us in our tracks. We were gutted as this meant we were starting the big race in the back of pack! Once we back to Hammer Town the fun began and we started fixing the long list new problems. Before the green flag on Friday the team fixed and improved the link bracket, replaced all the link bolts, swapped in a new front driveline, fixed another coolant leak, fixed the alternator, made new misalignment spacers, made a new motor mount, replaced a hiem joint, and pulled the front shocks for King to replace the bent shafts.

Super cool buggy. Thanks for sharing your story with us. Very cool to see and hear what you overcame to keep your racing dream alive.....Like taking on a build with no where to do it....:eek::eek::eek::eek:

Edit: I'm Curious.....who do you work for in the oil patch in Houston? I was there for 10 years and my brother is still there.
 
By Friday we were ready to race. Starting in the back of the pack, we knew we had to claw back as many positions as we could before the rocks! We lined up next to another rookie, #1717, when the flag dropped we beat them off the line, they were catching up to us until the first corner were we had the inside line and out braked them. We cleared the short course in front of the #1717 and headed out into the desert. By the time we had reached Balwin’s jump we had caught up to and started passing the cars that started ahead of us. We pushed as hard as we could in the massive dust clouds trying to pass as many cars as possible before the rock trails. The shock tuning with Ryan at AccuTune was paying dividends for us!

Here is the start of the race until the GoPro over heated:


By the end of lap 1 we had improved to 52nd up from 93rd. We got stuck in traffic at Thor’s Hammer, had a flop that we self-righted with our Warn winch, and by the start of Jack Hammer we had worked our way up to 27th! However, at the top of Jack Hammer on Option 2 our steering mount broke, taking us out of the race.

Where our race ended.

We then wrapped the winch line around the ram/ ram mount and were able to limp our way to the side post at the top of Sledge.

At this point we decided we needed a welder to get the car out. Started hiking down to find our pit crew and figure out how to get our generator welder to the car. Luckily, we ran into Victor and CJ in the Kawl Tek #4572 while hiking down Sledgehammer and amazingly they had a Karnage Welder in their car!!! We hiked that welder back to our car and were able to get the steering ram welded on good enough to get out of Sledgehammer!!!

Back home from KOH 2023 and started pulling the car apart to make all the needed repairs.

Damage included the broken ram mount, a elongated hole for the front axle driver side upper link bolt, a headlight that the bolts backed out of, burned up spark plug wires, bent drive shaft, bent shock bolts, and a few of the cylinders had low compression.

Got the motor pulled and sent off for a rebuild, the front axle out, and sent the shocks off for a rebuild.

Cleaned off the off the old ram mount and designed a new one.

Brought the axle over to a friends garage to weld on the new mount. I ordered the new mount in A572/A1018 and we wanted to tig weld it. My old Eastwood tig welder had stopped working, plus he is a much better welder than I am.

Brought the axle back home and welded on a recycled bash bar from the old mount. Got some new ram mounts that prevented the ends of the ram from backing out as well, and the motor came back with a fresh hone and new rings.

One of the big lessons learn at King of Hammers last year was that all the suspension bolts need to be properly shanked.
During the rebuild I took everything an extra step and jumped up to fine thread grade 9 bolts, deformed thread lock nuts, and did away with the old 7/8"x3/4" hiems with spacers replacing them with 7/8"x7/8" hiem with actual misalignment spacers. This required some machining to get the new misalignments to work on my brackets but I think it will be worth it for the extra piece of mind on race day.

Got the car prepped and headed to Disney OK for our next race.
