3.95:1 1st gear x 2.57:1 low range x 4.7:1 low low x 4.30 = insane low. I'm getting 205:1, if those numbers are correct. Regardless, this thing will be able to climb a vertical wall at idle without bogging. Its gonna be insane. Really looking forward to the rest of the mods. Keep em coming
Closest yet, but 1st gear is actually 3.83:1. Everything else is correct besides the final product, great job! Yeah I’m extremely excited to see what this thing will do with all that gear. I imagine I’ll want bigger tires before too long 😂
I think you now have 216:1 give or take. Also, Tom Woods now has a Toyota HD Shaft, it was recommended as I now have dual cases (but only with 135:1 final wheel ratio). The Tom Woods was made for that Utah Yota guy who chopped and swapped his FJCruiser. I also had issues with fitting it under the body, and had to do a 1 inch lift. I also am having a buddy install the frontrange t-case cross member, just to add some stability there. should fit.
Did you ever get around to installing this? I manual swapped my 4.7L Tundra with the same transmission you have in your Tacoma and I want to do the t case doubler with the low gears too so this video is awesome ⚙️
I actually don’t have it in yet, bunch of stuff has come up and I’ve taken a short hiatus from wrenching on the truck, much to my annoyance. This is high on the list though, I’m going to build the crossmember for it shortly and will definitely have a video on the whole thing
Seth, totally unrelated but didnt have a clue how to get your attention for timely question burning in my brain. A while, while, while back you posted your upgrade from billy 51s to Icon 2.0. I was recommended by Shock Surplus to upgrade from 51s to Icon 2.0 to add more rigidity to my rear. Will the Icons be able to support more weight preventing me from bottoming out? How did they work for you, how was their longevity? THanks
Just saw your question! I still have those shocks on my truck, and they still work quite well. 10/10 on longevity. However, your leaf springs will be supporting the load, the shock is mostly just providing damping. The valving of the shock will play a slight role in how rough it rides, but if you’re looking for more significantly more support in the rear of the truck, you should be looking at heavier leaf packs.
Given you've got a '99 TRDOR with manual 1st gear should be 3.42:1, and t-case low is 2.57:1... Add in the 4.7:1 dual box & Stock crawl ratio 37.79442:1 Dual case 177.63377:1
I had a Toyota hilux with the horrible bench seat in it, I swapped em out for Nissan Pathfinder seats I pulled from a pick and pull. You’ll have to drill holes and use shims but it’s worth it for a pair of seats that aren’t too expensive and better than the bench
@@michaelmcchesney1268 No need for apologies, totally understandable confusion! No pilgrimage for me this year, I've got a few other off-road events lined up around that time.
Did you do part 2 with install ?
i had inchworm gear and a dual case setup in my white 92 4runner. its good to have some buddies with a similar setup to wheel together.

Also close with the calcs! Thanks for the heads up on the TW shaft, gotta call them up at some point soon and have a chat.
You get this in ? I just got one for my Tacoma where’s video 2 !!

Thanks for the support!
dual transmissions are the best

Hey great suggestion!! I’ll keep that in mind…might be taking a trip to the pick and pull!
@@S0nnenberg also I forgot to mention if you find a 4Runner that’s the same generation as your truck then the seats will just bolt right in
Love the shirt! Getterdone!
77.4:1 crawl ratio? Nice.
This is close! I should've specified if I was in "double low"
@@S0nnenberg oh sorry, thought you were replacing the stock case, not adding to it! You heading to Pilgrimage this year?

85-95 4runner 4x4 rear stock driveline will fit your dual case setup
It’s possible, though with the 63s this thing flexes like mad and is quite a bit higher in the rear. Will still probably go custom!
