how old is your Budget Boost

For those of you that have done a 2" budget boost (coil spacers). What size tires have you gone with and how long have you had it installed? What kind of problems has it caused, suspension wise, that you had to maintain or replace?

Also I hear a lot of people doing tcase drops and mml. To me I don't see how doing both would help. Wouldn't doing both just put the angles back to where they were stock with the lift?

Thanks

Not 2'', but I have a 1.5'' BB. Installed it 2 years ago. Running 265/75/r16's (equivalent to about a 31.5'' tire). I've had absolutely no problems. I don't have a tcase drop or mml. It was a great way to get a slightly bigger tire on, but I'm planning on getting rid of it soon and going with a 2.5'' - 3'' suspension lift and 33's. I have an '03 rubicon, btw

I installed mine 2 weeks ago and I have no issues. Replaced shocks as well, and had adjustable (length) JKS disconnects.

A coil spring spacer doesn't change much on the geometry of the suspension, which is why the spacer is basically all you need. A motor mount lift and transfer case are both increasing the angle the t-case points down at. So they would add together not cancel each other out. Think of the engine, transmission, and tcase all bolted together as a solid unit. If you raise the motor end and not the tcase end it tilts back a little. If you lower the tcase end and the engine end stays the same it also tilts.

but arent you dropping the tcase 1" so that goes down. Then the mml is a 1 inch spacer and that raises the engine up....

The mml is towards the front of the jeep and tcase drop is closer to the rear. If you raise front mount and lower rear mount, that will cause the angle to change. Hope that helps.

And I had my bb for 2 years. Running 32x11.5 Goodyear mtr-k. No complaints besides the itch to go bigger!

ok, i think i got it... if its a 2" bb then the tcase goes down one inch and the mml goes up one inch creating even geometry.

If anyone else has done the lift let me know if anything wore out in the years you had it.

thanks

If you raise the engine, the yoke on the transfer case will aim down. It will pivot the whole engine/transmission/transfer case assembly on the hinge on the transfer case mount bracket.

A BB is not going to cause anything to wear out any faster.

So if I wanted to get the rake out, and didn't want to have to spend a ton of money fixing other things that a bigger lift might cause, would this spacer set be a good option?

That is true but the bigger tires add more stress on the suspension.

I have a 2"BB which is now 4 or 5 years old. As of today no problems. I'm running 31x10.50. I did have to drop the TC but I used 4 washers on each bolt works fine.

So if I want to go with a 2 inch spacer lift I have to do stuff to the motor mounts and transfer case? I can't just put the spacer lift on and then the bigger tires and leave everything else alone?

Many of us have been running much bigger lifts and tires for many years. You have NOTHING to worry about with a BB and 31's

With a 2" BB do you need a rear trackbar relocation bracket?

You don't need to do anything else with a 2" BB. You only need to extend the bump stops and they may come with the BB and it's a good idea to get longer shocks. In my case the kit came with new bump stops and shocks.

Ya 31's wouldnt cause to many probs its when you go for the 33's

I just dropped off my tj to get the 2" bb installed with some hubcentric wheel spacers to fit a 12.5 inch wide tire.

Ill post some b4 and after shots later today if all goes well. Im leaving on my 31's for the time being until i can afford the 33's or maybe 32's im not sure

ok its to dark for pics unfortunately, but i got the bb on with the bump stop extensions and wheel spacers for when i get new tires. rides great really not much of a difference, i used my stock shocks. only trouble was my bump stops in the front. my tec said they crumbled in his hand. so i dont have them in the front. since this is just for the road i think ill just skip the front ones.

pics to come soon.

The rear of my jeep was .5" taller than the front b4 the lift and obviously its still taller after the lift. is this common or have my coils lost their stiffness in the front?

i would like to buy the yokohama geolander mt + 33x12.5r15 has anyone measured them and know if they are 33's or a little taller / smaller? i need to be careful so i fit in my parking garage at my apt complex.
