580:1 Triple Case Demonstration in a 3rd gen 2016 Toyota Tacoma

The slowest Tacoma in the world!

BigMike took his 2016 Tacoma out for a shakedown run with his new Marlin Crawler Triple Case Setup comprising of a Marlin Crawler 2.28:1 MC08 Crawl Box, a Marlin Crawler 4.70:1 TacoBox, and the factory 2.57:1 transfer case.

Thanks to the Marlin Crawler, BigMike's transfer case now has 8 different gears for a combined reduction of 27.54:1.
Available t/case gear ratios are all selectable as follows:
1. 1.00 * City/Highway driving
2. 2.28 * To demonstrate factory Hilux gear ratio
3. 4.70 * Marlin Crawler Chromoly Total-Spline gear ratio
4. 2.57 * Stock Tacoma gear ratio
5. 5.86 * To demonstrate "Double Low" Marlin Crawler ratio
6. 10.72 * To demonstrate "Dual Ultimate" Marlin Crawler Hilux-style gear ratio
7. 12.08 * To demonstrate "Dual Ultimate" Marlin Crawler Tacoma-style gear ratio
8. 27.54 * Crazy, ridiculous "Triple Ultimate" Marlin Crawler Tacoma-style gear ratio

The Tacoma itself has 56 different speeds: 48-forward and 8-reverse.

The Marlin Crawler TacoBox provides the following benefits:
- Increased Traction
- Increased Torque
- Increased Control
- Increased Reaction Time
While simultaneously...
- Decreased bouncing
- Decreased risk of breaking...anything
- Decreased trail abuse
- Decreased overall risk to both vehicle, occupants, and cargo

The Marlin Crawler TacoBox Transfer Case system is compatible with 1995 and newer 2.7-liter (3RZ-FE/2TR-FE), 3.4-liter (5VZ-FE), 3.5-liter (2GR-FKS), 4.0-liter (1GR-FE), and 4.7-liter (2UZ-FE) Toyota 4WD drive trains, both manual or automatic setups.

Idling in 1st gear @ 580:1, this truck is moving 0.11 MPH or 9.08 HPM (that's Hours Per Mile).

In reference to the 6,000 TQ at an idle, this is a very conservative estimation. Explanation: Consider how much torque is developed by the engine at an idle. You have trace amount of air and fuel entering to maintain 800 RPM, and you have the potential energy stored in rotating objects such as the crankshaft and 35+ pound flywheel, pressure plate, and clutch disc (or flexplate + torque converter for autos). This energy translates to torque byway of rotational inertia. Imagine reaching out with your hands and trying to stop a truck flywheel at 800 RPM. It has a lot of stored energy. And that does not include air+fuel entering the engine.

If we use a very conservative estimate of 10 lb-ft torque at an idle, excluding minor parasitic losses we have 10 TQ * 580:1 = 5,800 lb-ft torque ... and we haven't even hit the throttle yet. BigMike has not done inertia calculations yet, but he is certain the torque is higher, especially considering how the ECU will fight to maintain idle speed. It is probably closer to 20 lb-ft torque developed at an idle without any throttle input. In such case, you'd have 11,600 lb-ft of torque...at...an...idle! Such is the true power of the Marlin Crawler Transfer Case System.

What if you want to drive over 2 rocks?... in the same day

[Star-xqtp]

That was equally the most fascinating and boring truck video I have ever seen

[merkinyall]

I have this in my truck and I fell asleep in my driveway once and accidentally drove over my house

[URBANAMERICANTAC]

With my luck, I’d have locked myself out.

[MrErichonda]

This would be the speed of my afternoon commute in the bay area.

[JohnMatrixOfficial]

Legend has it, it's still crawling!

[brycejcox]

That will come in handy for both rock crawling and cruisin down the 405!

[gabrielcornejo]

Nice demonstration.
6, 000 lb-ft of torque is amazing

[greynolds]

Electric cars: we have all our torque available at 1 rpm


marlin crawler: *hold my torque multiplcation*

[hilltoprestoration]

It's impressive, I'll give you that.
I just don't have a weeks worth of time to get thru the park.

[strflexin]

I see this everyday going to Fresno City College never knew you had a youtube channel. It’s nice to see this thing in action.

[johnmadsen]

That’s great at 800 rpm. Lets see it at 8000 rpm.

[ололо-ъз]

"When you want to take a nap while climbing this slope".
Impressive.

[NoNonsenseKnowHow]

Awesome demo! Very enjoyable to watch

[EhBrokenToaster]

Legend has it it's still crawling in that direction today, and has become an unstoppable force that will eventually demolish everything in its path..

[oneshotpete.]

I think I’ve watched this video over 20 X s, it never gets old !! Absolutely love that set up ... in vary near future I’m going to order my vary on Taco 🌮 Box ..

[obamadontreadgood]

Without question, that's the first time I've ever seen a driver crawl under their own rig to check out the drive train while the rig is crawling up something.

Killer job on this truck. Really looking forward to getting the RCLT and the MARACK on my second gen.

[Greenbean]

That rocks! And SO much cheaper than a Unimog! And a sweet demonstration too guys, keep up the good work!

[monsterram]

6000 lb/ft torque at idle... and 1 horsepower!

[markmitzlaff]

Man that was beautiful. Great traction from those tires as well.
