Topic: tundra dual case questions

[apimpdad]

i have been doing a lot of research on here lately and decided to join, but i have some questions about the dual case setup for the tundra.  I have an 02 SAS tundra and i am wanting to put a dual setup in, but i saw the joe had a manual shift t-case installed behind the marlin case, can i keep the electronic t-case if i did this setup?

anyone?

I sent a PM to Mike for ya.

Thankyou Glen and Mini for the heads up here.

apimpdad, and thanks for joining!

Yes, you can keep the electronic factory shifting with the t/case on our Tundra Dual Case setup. The reason Joe did not, is because he wanted a Twin Stick, and also, I *think* there might be an inherent weakness in the viscous coupler in your t/case, but I am not sure. I will check with Marlin on this.

another newbie question, what is the shift pattern for the dual case, is it just the 1:1 and then shift down to 2.28:1   

[apimpdad [OP]]

anyone? any updates?

[apimpdad [OP]]

also, what are the spline counts that are used with this setup?

....... help?  I tried to sent bigmike a message but it wouldn't let me???

You have to have at least 12 posts to send PMs

oh, i didnt know that, thanks

Regarding the transfer case, we have never used one. Marlin says he would assume it to be just as strong as the non-center differential t/case, however not all Tundras have this feature. It may be a more rare occurrence that needs furtherer investigation.

another newbie question, what is the shift pattern for the dual case, is it just the 1:1 and then shift down to 2.28:1   

That is correct. Low-Neutral-High. High range is 1:1 on all of our products, and low range is 2:28 (default) or our optional Total-Spline 4.70:1 gearing. A/A 4.00 and 4.97:1 gear ratios are also available however I would highly recommend against using them with a V8 due to their weaker design.

also, what are the spline counts that are used with this setup?

All of the spline counts here are 23-spline. 23-spline Tundra Auto output, 23-spline Marlin Crawl Box input, 23-spline Marlin Crawl Box coupler output, 23-spline Tundra Chain Drive t/case.

Mike, if you want you can install a crawler in my 4Runner with the AWD/4WD TCase and I'll test it out for you guys for free!

thanks guys for the info, very helpful.  Also, which setup is the one that i would need to order, i am thinking its is the tacoma taco box, part number MC-14572, is this correct?

[apimpdad [OP]]

anyone, i need to know the part number??? i think its MC-14572.....

[apimpdad [OP]]

i need a part number!!! anyone?

[apimpdad [OP]]

anyone know the part number to this?  since i have been on the part numbers have changed.... any help?

[dirtchicken]

Have you tried calling the shop??

[apimpdad [OP]]

yea, no answer.  i have sent a pm to bigmike also and still no response

[apimpdad [OP]]
