This is a discussion thread titled "Tundra 2.5" Lift Advise", within the Suspension & Axle forum, part of the Technical & Vehicle Assistance Forums category.
Just stumbled across this site the other day, it's awesome!! Lots of great information.
I have a 2002 Tundra TRD 4x4 and I absolutly love it.
I want to put a 2.5" suspension lift on it to give me room for 285/75 R16 BF all terrains and have some questions.
Pretty basic lift: spring spacers in front (2.5") and either add-a-leaf or blocks in the rear (1.5")
My first question is regarding the rear. I would prefer to use add-a-leaf because I feel that it is better than blocks. I know that it will stiffen the stock ride. Any thoughts??
Secondly, some kits contain front differential spacer kit to help strain on CV joints. Any thought????
Thirdly, has anyone put 285/75 R16's on the alloy TRD rims? Some of the reading I have seen recomends backspacing of about 4". I also understand that I could keep the tires from rubbing by adjusting the front bump stops. Any thoughts????
It would be great if you guys could help steer my in the right direction.
The add-a-leafs will not necessarily stiffen the ride. Typically the new spring goes next to the overload leaf and it only comes into play when a heavy load is placed in the bed. You will probably see about a 1/2" - 1" lift in the rear as a result.
The front diff spacer helps to maintain the correct angle between the diff and the CV's. I would recommend it.
For your 3rd question, I don't have any personal experience with that one. I'm sure others will chime in.

I'd have to agree with Herbicidal. AAL's won't nessesarily stiffen the ride.

That CERTAINLY is a wise investment, especially considering that you're looking a 2.5" of lift. I bought my diff drop kit from another TS.com member, primarily as a "precautionary measure". Nothing like a little preventative maintenance. Of course the alternative of leaving this kit out, could and has for some TS.com members, caused the CV boots to start spewing grease, with a 2.5" lift.

The "stock" alloys don't have enough back spacing to accomidate the 285's, no matter how much lift you use. You'll have some frame rub any way you look at it, using the stock TRD wheels. Most TS.com members here who have opted for the 285's, have had to purchase a set of aftermarket wheels with more back spacing. Not sure how much exactly, but something tells me, you're at least in the ball park with 4".

Never heard this one?! It's certainly news to me. Maybe another TS.com member can help on that, although I have my doubts that this is correct.

I am running 285/75 R16 bridgestones on the stock rims. The tires fit, but you will rub on the frame with the driver side tire. You can either go with a rim with less BS, but it will put more tire into the rear of the fenders when you turn.
To adjust the steering stops, you just tack weld on some spacers ie 1/2" or 3/4" nuts on to the opposite steering stop. To find the steering stop, just turn your wheels and have a look near the bottom of the spindles on the front side.
