Builds Trifecta Build Thread - KOH EMC, Cruise Moab, Rubithon (1 Viewer)

[RustyNailJustin]

Finally had a chance to read your thread on Pirate - what an amazing journey with the 4619! Given your experience, i’m Relying on you and others to let me know if I start heading down the wrong path.

I’m guessing the 4619 took 2018 EMC off?

Yes after Nitto Nationals, and having a bunch of mechanical issues, getting a ton of spare parts stolen out of our race trailer. I needed a break. Just to bitter to pour my heart into it and that's what it takes to win and we have been on the edge of a 1st for years!

Another Update:
Over the weekend I started thinking about the KOH Rulebook and the Trifecta Build. I concluded that the race organizers wisely designed the 4600 rules to balance two things:

1) Retaining the look/feel on OEM rules, allowing vehicles to cater to the majority of "Every Man's" vehicle owners out there and allowing sponsors to showcase their products in the "World's Toughest Off-Road Race"

While also:

2) Permitting an "anything goes" mentality for the critical, most prone-to-failure portions of the drive train to give 4600 class rigs a fighting chance to actually survive the race.

With this in mind, I concluded that participants (me included) better take advantage of any and all permissions in the rule book in order to have the best chance of survival for their sponsors and themselves.

So, for the Trifecta Build, this means we cannot cut corners on critical drive-train and performance areas of the build just to try and save a few bucks.

Therefore, here is my latest build plan after a weekend of research:

Vehicle: '06-09 Toyota 4Runner v8 Sport

Front:
- Front IFS Long Travel Kit (3.5" to keep Track Width 7" from Stock)
- Currie F9 IFS Front Differential (4.88s or 5.29s and ARB Locker)
- RCV Ultimate IFS CV Axles
- Front Fabricated/Gusseted Spindles, Steering/Clevis, and Shock Hoop, and other Gusset/Bracing upgrades
- Front 10-14" King Dual Rate Coilovers with RR
- HD Steering (Custom or Modified Tundra Rack)
- HD Driveshaft

Rear:
- Aftermarket Housing, Toyota 9.5" Diff, 4.88s or 5.29s, ARB, Chromoly Shafts
- Rear HD 4-Link Kit (Aftermarket HD links or Custom 4-link with factory fuel tank out of the way)
- Rear Long Travel Progressive Rate Heavy Coil Springs
- Rear 10-14" King Shocks with RR

Drivetrain:
- Stock Toyota 4.7L V8
- Stock Automatic Transmission
- Atlas II Transfer Case
- HD Driveshafts (F/R)

Other:
- 35x12.50r17 Tires (must be tall - as close to a true 35 as possible)
- 17" Beadlock wheels
- Front Aluminum Bumper (Pelfreybilt or Addicted Offroad)
- Rear Aluminum Bumper (4x4 Labs or Other)
- HD Sliders and possibly Boat Side protection below door sills
- Warn Winch, Full Length Skidplates, Upgraded Bump Stops, Brake Lines, etc.
- Spare Tire, Aluminum Fuel Cell, & Battery in the Cargo Area
- Fiberglass Fenders (4.5" Bulge)
- Roll Cage, Harnesses, Suspension Seats and other Safety Stuff Required
- LED Lights (F/R), Spare Parts, and other Race Stuff Required

Honestly, I simply cannot afford the build above. But both KOH EMC and the Toyota "Every Man" Enthusiast across the world deserves to see it happen.

So, I'm ramping up my efforts and proactively reaching out to key sponsors and spreading the word. I'm also going to get on Instagram soon to amp up promotion more and possibly do other forum threads. I believe if someone has a great idea and is passionate enough and committed enough to work hard to see it to fruition, others will rally around it and help make it happen, together.

If anyone has any connections with potential sponsors or other "outside the box" ideas to help ensure this happens, I'm all ears!

49 Weeks To Go!

I'm still debating what to do with the rear axle and suspension.

Rear Axle: The front width will be expanded by 9" total. I'd like to match that on the rear.
- I'm assuming I need Dana 60 equivalent? Any suggestions?
- Maybe something from Currie to match the front? I wonder if Currie makes a front diff for IFS? Maybe I need to call them next.

Rear Suspension: We have to keep coils and can only have 1 shock, but anything goes otherwise.
- Are there any over-engineered rear 4-link kits, preferably eliminating the panhard bar, that can hold up to KOH?
- Or would I have to start buying parts from Ruff Stuff or someone like 4WheelUnderground?
- Ideally we get around 21"+ of rear travel out of coils. Is this possible? Are there dual rate, long travel coils out there that work outside a Coilover?

Thoughts?

I'd look hard into a "Jana 76". See if you can also get Jantz to set up the gears for you (it'll cost you some $ in shipping there and back, but Carl Jantz is a wizard with gears) and install the load bolt. You'll get the benefits of the clearance of the Dana 60 housing, with Dana 70 strength. This whole upgrade, if done yourself, is only about $400. Dana 70 lockers and gears are a wash in comparison to Dana 60 (within a few dollars of eachother).
Make sure to invest in a heavy duty sway bar to tame that rear axle in the fast stuff and help out with body sway in the rocks.
Good luck on the IFS front. You're pushing a lot of weight (something the IFS buggies are not contending with), which leads to a lot of wear on IFS components. I'd expect to treat every component in the front end as a race maintenance item and be very aggressive about replacing components.
