96 Toyota T100 SR5 SAS

I Have a 96 Toyota T100 lifted on 33's. I want to do an SAS and would like any information on this upgrade. I have found a Chevy 6 lug Dana 44 to match my rear axle. I want to run 37's. I was wondering which would be better 4.88's or 5.13's. I have seen other forums with the T's running 4.88 but I feel like that might not be enough. Any suggestions?

5.13's... as long as you remember you can only use 4wd in slow speed offroad / very slippery situations. (unless you get a matching 5.13 rear axle). The mismatched gear ratio's will bind up your driveline....
I'd only go 4.88's if you had a V8...

I wouldn't run different gears. I will replace the gears in both my stock rear axle and the Dana 44 I will use for the swap. Most of the forums I have seen for this upgrade all run 4.88's.

For the Dana you can only run 5.13 or 4.88, for the toyota you can only run 4.88 or 5.29.
If you want to have matching gears, you have to run 4.88's, or swap both axles to the same type (both toyota or both dana).

Go 4.88 then. 37's are IMHO too big for 4.88's on a stock motor, but if you see a supercharger in your future it will work OK.

That's what I was thinking about the 4.88. I was hoping I wouldn't need to replace both axles tho. Another question that has been puzzling me is what front drive shaft will work once the front axle is moved forward?

You want a 5.29/5.38 combo since it's a much closer match than 5.29/5.13.

I've got 5.29/5.38 in my 4runner with 37's and the 3.4 V6. It's a better setup than 4.88's if your goal is a lot of off road driving.
On-road with 5.29's the rpm's are a little high so freeway gas mileage suffers... but if you're running 37's gas mileage probably isn't your primary concern.

Also, the mismatch between 5.29 and 5.38 is only 1.7%. Not enough to worry about. I've been running it for well over a decade without issue, and many others have as well.

I am thinking of just swapping the rear so I can do a E-locker at some point. I'm pretty sure I'll run 5.13's. Do you have any idea what to do about the front drive shaft other than buying custom?

You can buy a flange for the D44 that will allow a Toy shaft to bolt up, but most likely you will be doing something custom for the front shaft anyway since if you run shackles at the rear of the front springs like most do, you'll probably be needing a long travel slip yoke.

What are the advantages for running the shackles at the front of the springs instead of the rear?

The axle moves forward under compression which keeps it away from your fenders.

However, for on road driving it is less stable because the axle will want to push forward over bumps... the ride will be like a FJ40.

Go rear shackles... smoother ride.

That was my plan... and to avoid hitting my fenders I was going to move the axle forward a couple of inches. What is the distance between centers of the spring perch mounts on a Dana 60 and a Chevy 14 bolt?

Sure you cant use a D44? Id think its more than enough for a T100. Wagoneer D44 I believe has proper side drop for T100 and alot more options for ratios can be had including your 5.13 and 4.88. Should hold 37s ok. its also the right width, dang near 62" i recall.

Ya the Dana 44 will be more than enough for 37's but I will run bigger tires at some point and I don't want to have to swap axles then. It will be easier to just go with a Dana 60 to start with. They make 5.13's for both the Dana 60 and the Chevy 14 bolt.

Dang, bigger than 37s? I cant wait to see what it looks like with 37s let alone larger tires.

Here is a link with a T100 running 42in Iroks with bobbed bed. http://board.marlincrawler.com/index.php?topic=31519.0 This rig is sweet... close to what I'm shooting for.

Realized I have another problem. A HP Dana60's diff is on the drivers side not the passengers. I don't really want to do any cutting and welding on an axle to make it work but that might be the best option. I have looked at using an FJ80 axle but I have found that it is rather hard to get the steering to work. A Dana44 would fit the best but I fear it wont be strong enough for 40+in tires. My question is do they make a large axle like a Dana60 with the diff on the passenger side?

You may get some responses here, but for full width axles, pirate4x4.com is your best site.

That thing will be badass.

I came up with a crazy idea but I have no idea if it is even plausible. If I were to run a Dana60 with a drives side drop could I rotate my transfer case to the other side of my transmission? I have the feeling it can't be done because the out put from the transfer case would be spinning the wrong way. Any thoughts?

There are lubrication issues.

However, you should call marlin crawler or inchworn, as they do make left side drop t-cases...

I have done more research and I think I am either gonna go with a Dana 44 or bite the bullet and buy a passenger side drop Dana 60.

Well I recently bought a set of Dana 60's out of 84 Dodge W350. Turns out the length of the axles are almost exactly what the stock rear axle is in length and the spring perch mounts for the rear axles is the same as my stock one (44in from centers). The front axle's perch mounts are 33in if I remember correctly. I also traded my set of allterrain 33x12.5 R15 for a set and a half of goodyear wrangler 37x12.5 R16.5 with rims. <img src="/forums/images/graemlins/nana.gif" alt="" />
