Probably not, input shaft is the weak link. No wheel drive sucks. I would spring for an atlas with the setup your looking at.

As far as case strength, I got my tacoma hung up on a 8" diameter stump that was in the middle of some soupy ruts. With some harsh 2' back and forth each way I used the transfer case to rip the stump out of the ground. The little sheetmetal plate on the bottom of it is perfectly contoured to the aluminum underneath now.

which case? There are a few different models with a couple of different input shafts. I'm just shy of 300hp, 37s and duals. No problem holding up to that while driving to the mall

on the first gen tundra and sequoia and the v8 4runner, it uses a similar chain drive with over 340lb of torque stock. if i recall right, when trd made supercharger for the tundra/sequoia the transfer case was not the problem, the weak link was the rear diff.

My only requirement would be that it bolts to a marlin or tg Tacoma doubler. I ASSumed the tundra's had a different case/ pattern?

The outputs are 30 spl I believe, sound like it is the length of the input that is questionable?

I can take a picture of a stock 23 spline taco input compared to a stock 21 spline gear case input when get home. You can see just how much shorter it is.

Nevermind, can't get the coupler off the stock taco case. The other case I had slid right off but not this one.

Is it a matter of having a longer input made, or is there nowhere for the extra length to go?

I'm not sure how close the t-case input and the tranny output are to each other.

How close is the Tacoma case length-wise to a gear-driven mini case?

Mating surface of the Tacoma case to the rear flange is 12 1/2 inches. Gear case is roughly 12 3/4 inches, hard to measure Callens cases accurately with his crossmember onthe way.

Thanks Brad, I decided to pass on the taco crawler after calling marlin on Monday. I'll probably be going "lefty."

No standard Tacoma case but this is from a 2000 limited 4Runner with a 3.4L.

Mounting surface to rear output flange is 15 5/8"
The input is 4 1/16" from mounting surface to front of input.


If I remember correctly the 4cil input is around 2 5/8" from mounting surface to front of input.
