We're excited to announce that Cooper Tire and KMC Wheels have signed up to sponsor this King of the Hammers build.

We'll be running 315/70R17 Cooper Discoverer STT Pros:


These will be mounted on 17" KMC XD222 Enduro Beadlock Wheels:


With Cooper and KMC both on board, our sponsorship for KOH 2019 is officially full.  We'll have more to show on the tires and wheels, and from our other sponsors over the coming months.

Special thanks to BigMike who helped us land Cooper on this build!

Quick Build Update:
- RockSolidToys Rear 4-Link is done and ready to be installed once the front suspension is on
- Currie Rear RockJock 60 is in the middle of being built
- Salvage Doors (4) should be here next week.  Evidently they were were stuck in a "rail delay" somewhere between CA and Chicago.
- Salvage Liftgate and Sport Hood will ship out of NY tomorrow.
- Jaz Pro Sport II 22 Gal Fuel cell, Arctec Industries mounts, and Allstar 2.5" filler hose in the mail.
- Still working on Alltec Baffles and plumbing conversion, which I still need to learn a lot about
- AEM Air/Fuel Ratio Gauge, AEM Fuel Pressure Gauge, and URD 170 Deg Thermostat will be installed when URD MAF Calibrator arrives
- PRP Ivan Stewart Pro Seats and Harnesses should be shipped out soon
- Cooper Discoverer STT Pro Tires ordered
- KMC XD222 Enduro Beadlock Wheels will be ordered this week
- ABS (and ATRAC, VSC, and TRAC) Defeat Switch will be finished next week
- Atlas II 3.8 Case and A750F Adapter will likely be ordered next week

The salvage parts arriving next week will literally replace every single removable piece of sheet metal on the 4Runner.

I'm tracking every component of the build in a build-plan and checking things off the list as we go.  Still a lot left to do, but having the sponsorship portion of the build completed is a big win!

Order that atlas ASAP its like a 10-12 week wait.

Order that atlas ASAP its like a 10-12 week wait.

Yes, I know!  The sponsorship lead is currently out on a 2-week vacation!

I'm also going to see if they can help pushing this one through faster for us once he is back.

Nice parts list.

Im curious as to why youre replacing all of the doors and lift gate?

[Charles4x4 [OP]]

Im curious as to why youre replacing all of the doors and lift gate?

This is simple. My flawless, complete (glass, motors, electrical, etc) Limited exterior stuff is worth a lot. Salvage shell parts are cheap. I'd rather put on cheap salvage parts ready to be destroyed at KOH and sell the valuable parts so I can buy other stuff for the build.

I like your way of thinking!

[Charles4x4 [OP]]

Quick update:
- First, I was wrong! I installed the ABS Kill Switch and drove all this past week - I thought the 4.7L was fast before. With ABS off, it's a whole new beast.

You all were right! We will be running KOH with ABS Off. I still like the switch so I can have ABS on when I drive to CA in mid-Sept, but once it's in CA, it'll be off full time!

- Salvage parts have started to arrive and the remainder should be here this week (Liftgate will be gutted - glass, motors, electrical, etc will be sold):






- PRP seats are here. These will be installed on temp brackets as soon as this weekend for the drive to CA and integrated into the roll-cage in CA:


- Fuel cell, mount, filler, pump, filters, Alltech baffles etc will all be here this week and I hope to have rough mounting done this coming weekend. Only thing I lack here is the AN fittings and hoses.

- Master Kill Switch from Painless should also be here this week and installed this coming weekend.

- URD MAF Calibrator will be here on Friday and will be installed this coming weekend along with gauges.

- Cooper STT Pros and KMC Enduro Beadlock wheels have all been received and are stored at Marlin Crawler's shops in CA. I'll hopefully have some pics to post soon.

More to come soon!

[Charles4x4 [OP]]

JAZ Pro Sport II - 22 Gal race fuel cell just arrived from JEGS:


Slowly running out of space:


Also got the Painless Master Kill Switch, secondary latches, fuel line adapter for AEM AFR Gauge, and a few other odds and ends today:

[Rockcrawlintoy]

Looks good. I am looking forward to the build

- ABS (and ATRAC, VSC, and TRAC) Defeat Switch !   Lets have some more info on that!  a how to and parts list??  Id love to have a full ON/OFF switch to defeat instead of the VSC push button sequence

Here you go!  This is the simple mod I did:

Disable VSC, TRAC, and ABS without damaging factory wiring

More stuff that'll go in this weekend.  The big stuff is yet to come in CA, but it'll be good to check a ton of stuff off the list this weekend.

1) AllTech - No2Foam - Baffles (enough for a 24gal cell).  Thanks to Chris for sponsorsing this build!


2) Harnesses and angle mounts that we'll take to CA:


3) URD MAF Calibrator (to unlock any lost HP):


Doug Thorley Headers and Hi-Flow Cats should be done today.

I'd love to dyno it, but don't have the $'s in the budget.  My best guess is the 4.7L will be b/w 350-375 HP by the end of the weekend, but that may be overly optimistic.  Headers alone are a 30 HP gain.

[Charles4x4 [OP]]

After a month of tracking these down (railroad delays, lost shipments, delivered to the wrong address, etc), the 4 salvage doors finally arrived just in time for this weekend!

[zippo]

Dude. Get an led whip. Most important item. Will be the first thing I bolt onto my next rig.

Well, the guy in CA sent me 3rd gen doors on accident. Nice guy - refunded me on the spot. But it’s back to the drawing board on doors.

Tube doors with sheet metal skins are sounding better and better...

[Rockcrawlintoy]

 

Can’t be a wheeler at KOH without one

[Charles4x4 [OP]]

We had a huge push this past weekend.  Six friends came over to lend a hand.  Everyone was exhausted by the end.

1) Exterior tear-down complete:




2) Interior tear-down complete (and rear seats temporarily reinstalled until the drive to CA):




3) Fiberwerx Fenders and Salvage Hood Installed:






4) Salvage Rear Lift Gate installed (we had to tweak it back into place due to a prior roll-over):


5) Fuel/Air Ratio Gauge Installed / Fuel Pressure Gauge ready to go, but haven't found a place to tap into the lines just yet as the adapter we purchased didn't fit:


6) Master Kill Switch Installed, but I still have to find a place for the Big Red Button:




7) URD MAF Calibrator Installed, but I haven't tuned it with the provided software yet:


8) Drivers Seat Installed on temporary brackets (hopefully we'll keep the slider somehow - it's nice to be able to adjust the seat).  Passenger bracket was missing in the shipment, so it'll probably be here in a week.




9) Fuel skid removed, Fuel cell mount holes drilled and Artech mount installed.  Still need fuel line adapters before I can actually mount it and I need to drop the stock tank.

10) Doug Thorley Headers and hi-flow Cats installed late last week (engine video on Instagram and Facebook):






I'm probably forgetting a few things as it was a blur of a weekend.  It's nice to finally have the DD done so we could tear into it!

Master Kill Switch mounted:


The Kill Switch has been a learning experience.  The kit I have kills the battery, but the alternator keeps going. 

Their description:
"Our Master Disconnect kit with Emergency Push Button is perfect for race applications as it allows you to install a large push button in easy reach if you need to shut down your vehicle's electrical system in a hurry. Kit comes complete with one 250 AMP solenoid, one Emergency Push Button, wire, mounting hardware and connectors."

Per Painless, I have to either run the kit I have now through a HD disconnect:
http://www.painlessperformance.com/webcat/50710

Or run a second Alternator Kill Switch:
http://www.painlessperformance.com/webcat/50105

The Alternator kill switch keeps everything in the engine bay and I won't have to run tons of Starter and + Batter cables into the cab, so I'm leaning that way.

[Charles4x4 [OP]]

Pic of the heart of the Master Kill Switch wired in the engine bay - the plastic red push button simply finalizes the circuit ground once it is pressed.  This is the Heavy Duty portion of the Painless system:

[THK Matt]

Can you make it to where if you push one it leaves the other one on, but if you push the other it kills both circuits?

[:)bestgen4runner]

I'm surprised that this version is allowed. I expected the big switch like on a drag car would be required.

Yes, I'd just have to buy another switch.  But I'll never push it unless we're upside down and have to kill both.

It is a nice theft deterrent device though (but not very will hidden ).

Exactly my original plan as well.  The problem, as I have come to learn, is:
1) I have an alternator that I have to kill and just killing the battery won't kill the vehicle once it's running.
2) It has to be within reach of both occupants, which means I'd have to run a bunch of huge cables into the cab with marine style switches for both Battery and Alternator switches.
3) This is a very clean, easy to diagnose setup with fuses that can be swapped if we run into an issue.

In reality, the solenoid in the engine compartment is essentially one of those huge switches.  The button as simply the remote control that flips the switch from inside the cab - but allows you to easily mount, wire, and access it.

Is there a passage in the rule book describing this requirement in detail?
It doesn't call out for a mechanical battery disconnect? Just trying to help. all the racing I have ever been involved with required a mechanical disconnect (the big switch I posted) it also required the entire electrical system be run threw the same switch. this way one switch can shut down the entire system.
