Bringing this back to the board here!! It appears this could work for a tacoma. Putting tundra rears on a tacoma I mean. Cant find this anywhere else for some reseon. Theres a few dead end threads on other sites. Has no one really done this.

02 tundra rears measure 2 3/8 width And about 60'' bolt to bolt
02 taco rears measure 2 3/8 width And about 55'' bolt to bolt.

And i measured these in the rain so might not be perfect.

The real benefit here is the tundra leafs are not a negative spring. So lift without using a lift block are AAL. But might require a longer rear shackle, or possible relocation a hanger. But in my experience the tundra has nice rear springs.

Hanger relocation.
Axle wrap.

ThatGuy1295

Your saying there will be more axle wrap if the hanger is relocated?

ThatGuy1295

hmmm....

Yes. Longer leaf springs promotes axle wrap.

:wabbit2:

ThatGuy1295

Makes sense, but the tundra doesn't seem to have any axle wrap.

And what aboot chev 63's?

ThatGuy1295

Onn! Nobody uh?
Im the first to ever think of this? This is exciting.

ThatGuy1295

Personally I like the idea of using OEM parts, even if from another model yota, then use aftermarket stuff.

ThatGuy1295

And hold on here just a second.... Im talking about ways around lift blocks and AAL's

Those promote axle wrap waaayyyy worse than a 5'' inch longer pack.

You have a great point ^^^

ThatGuy1295

U mean it?


I mean is there any reseon this isn't a good idea?
Anybody who has a tundra knows they have pretty nice rear springs.
But looks like it would give you aboot a 3'' lift from stock. But hard to tell without doing it. Thats why I was hoping somebody has.
I have a 3'' lift on the tacoma now, and the rears suck. Id rather go with a spring that makes it sit level with the front without blocks or AAL's.

And chev springs are realllly long.

tundra springs are gonna be pretty stiff for your taco.

ThatGuy1295

Its possible.

My girl friend has an 02 tundra with the 4.7. Ive had the opportunity to see what the tundra and my taco both weigh at the local garbage dump, oh sorry (waste recovery center).

Anyways there pretty close. Mine has winch bumper, dual batteries, and a tool box. But there within a few hundred pounds. Mine said like 4600, and the tundra was 4790 or somthin.

Anyways, my point is while the front of the tundra might be heavy with the V8, I don't think the rears are much different empty. And the body can't be to much heavier, the tundras did come with the 3.4 V6. Not that anyone bought them.

Weighed the taco one time with all my work tools in it. 4950lbs.

Also noticed with 2 dirt bikes in the back of the taco, while towing a 3000lbs camping trailer with a tung weight of 350lbs ish, that the stock springs are completely relying on the overload. And still about a 1.5'' from the bumpstop. But when you hit a bump its like you don't have springs at all. Feels like the old 1980's 3 wheelers with no suspension.

But, same exact bikes with the same trailer, on the tundra, its noticeably better. The truck still squats about the same amount, but still behaves like it has suspension.

I gotta agree with web here on the axle wrap issue. I know the t100's have axle wrap issues, it's been covered on here before. Now, I know the tundras have a three leaf pack with an overload compared with the t100's two leaf and overload, but on a Tacoma, with a lighter rear end compared to the tundra, I believe that axle wrap would be a little more prevalent.

With that being said, I would love to see you try it. That's the only way we can find new ideas and solutions to different issues. Might even be worth a try on my t.

mokai

Yes I meant it. You bring up allot of great points.
I have a 1" block and airbags that give me about a 3" lift in the back with 5lbs of air in the bags. Rides great empty and with a load I just add more air with the in cab controller. Great setup.

bringing back an old post
ive been on this site befor for info but havent posted so i figued i would share my info on this topic

just recently picked up some 2000 tundra sr5 extened cab blisten front shock and rear leaf spring for my 98 tacoma v6 extened cab



the leaf sping measure the same width but the tacoma are 55" and the tundra are 60"
my leaf springs i was also running 3" blocks


tacoma vs tundra







i got them mounted but had to go back to the tacoma leafs becuase the center bolt is futher back causing my drive shaft to come apart when trying to mount the rear end. also for shock it looks like the shocks will need to be atleast 28" long ebake cable needs to be re routed and a brake line will need to be made longer also the rear shackle was resting agianst the frame

ThatGuy1295

Awsome info. Glad somebody actually investigated it. I do feel that the center bolt could be re-drilled to match the tacoma making your driveline work as it was supposed to, but throwing of u-joint angles and needing shims. Not the first time thats been done lol. But still would require some custom fabing for the other stuff and rear shackle to be moved back. And from the looks of those tundra springs they would give you a bit of lift running them on a taco. They are ran differently on the tundra then the taco springs are ran. Reverse shackle and outside the frame rail as apposed to directly under the frame rail, wich is essentially a lifted geometry all on its own, but toyota used a flat spring in that position, as a result, the stock height. IMO a bad spring design on the stock taco's for many reseons. You can see were the appeal of running a semi arched spring would be a world of difference.

i removed the tundra shackle to install on the tacoma. im gonna looking into running a tundra driveshaft if it longer my plan is to eventually swap a tundra 4.7 into the tacoma. i thought about redrilling a hole my consern was that it wouldnt be center on the leaf would that cause problems

ThatGuy1295

Well its already not centered on the leafs, just like lots of springs are from the factory. Especially the stock tacoma springs. My thoughts on drivlines for this or any other spring swap are to go 1 piece drive shaft anyways. Besides if you swap engines and try to run a tundra 2 piece shaft the carrier bearing is no where near where the bolts on your taco frame go. 2 totaly different drive shaft setups.
