Walking the Crawler while discussing ratios

Here Marlin Czajkowski from Marlin Crawler, Inc. discusses his transmission ratios to spectators while the world-famous Crawler truck makes it's way up to the top of a steep rock climb in 1st gear, 1,372:1 Crawl Ratio. Trail: Jackhammer, Johnson Valley, California.

Thanks for the comment! It has 35 forward gears and 5 reverse gears! -BigMike

3 reduction cases in all, saw the tech artical in Toyota 4wd owner, sick truck i love it

Hey guys, thanks for all the comments! In the other video where I refer to Marlin's truck as being in 13th gear, it was analogous to a bicycle: Consider a 21 speed where you have 3 chainrings and a 7 gear cassette: You only have 7 gears at the cassette, yet there are 21 possible gear combinations thanks to the front 3 chain rings. Also, as ratios overlap, for instance 1st chain ring + 7th cog will be a higher ratio than the 2nd chain ring + 1st cog. Likewise, with Marlin's Triple Transfercases.

marlin runs 2 reduction boxs and the stock tranfercase

Prototypexl , on toyotas there is to parts to the transfer case,1st 1/2is the reduction box, it is what what allows either 1:1 (high range) or 2.28:1 (stock low range)the 2nd 1/2swaps between 2 or 4wd,both are controlled by the same shifter at the same time (stock set up).i'm not sure in this case what recution gear boxs r used (there is aftermarket boxs and you can swap in other makes and modles with ther right adaptors) but there is 2 reduction gear boxs infront of the stock transfer case.

It has a dual reduction house, so not only do you have low 4 wheel drive, you have low low 4 and put it in 1st and you are going that slow!

[@Prototypexl]

Yeah basically. I love it!

[@cody3362]

I would love to know how much torque that is making

[@Prototypexl]

But that doesn't answer my question...is he indeed in 13th gear or is the gear ratio EQUIVALENT to 13th gear?? I'm just trying to understand this whole thing. I know what the transfer case is, not quite sure how it works, but what is a reduction box??

[@Prototypexl]

But it would be a 10 speed even if manual. Wouldn't it...? Not sure being I'm new to the 4x4 community. 13th gear is like having two 7 speed manual gearboxes..........right?

[@Prototypexl]

Wait a minute....I just watched your other video in 13th gear.....how the HELL do you get into 13th gear?!?!?

wow maybe too slow lol nice truck
