Add a Leafs WILL cause sagging.. spend an extra $200 and go with full leaf packs. In the long run that's the way to go

 

I have 1 1/2 inch blocks, never had a problem with them.

 

I just look at your profile and if you're still running those stock wheels you will not be able to use 3 inch blocks unless you remove your rear sway bar, the end of the sway bar will hit the tire if you don't.

 

Personally i would stay away from blocks. On my old truck i had them on the front and rear, went mudding and the axle wrapped and snapped my leafs. IMO i would say bastard pack.

 

The higher the blocks, the more problems they cause, If you put those 3 inch blocks on your rig I'd never go off road with it if I were you.

 

I saw it happen with a cherokee that was behind my jeep trying to tackling this hill:



I walked right up it with my tj but the yj behind me got stuck and needed winched. Next came the xj with 2" lift blocks and acos front spacers running 32's with badly messed up fenders. The front end got up on the hill and it was flexed out. When gunned it the pinion moved around 4" up and down as he hit the accelerator. The leaf spring was no where near arched like it should be when this was happening. It was a renix era xj with worn springs.

here's an example of what it looked like:


Imagine how bad it would be with lift blocks making the leverage even worse.

 

Im currently running a 2" block and they work however not the greatest.. Be easy on the skinny peddle and you be ok. However the do make ur spings want to arc the wrong way after time.. Im going to be bastard packing my truck soon its really easy and probably your best bet to keep cost down.. btw im 18 on a college budget so I know how it goes!

 

Do not...do not...do not use blocks. Talking from experience.

 

I gotta to add my 2 cents. Although I have never used blocks before, I do have the Zone off-road 3" AAL kit, and I've had it installed for about a year now. And I have no visible sagging at all. I'm very pleased. I also have been off-road about every weekend for the past summer. Just my 2 cents.

I'm also looking to add 2", possible shackles, but I'm not sure yet, still looking at options.

Good luck with your build, and keep in mind that this will be a huge, and good learning experience for you in the world of Jeep, as it has been for me.

Can't wait to see the finished build.

i have no experience with blocks or aal.. i went with 2" shackles which installing (im on day 3) is a PAIN.. have to replace all 4 leaf spring bushings and to be honest i sure wish i bought a AAL or blocks for that matter..

 

Bolts seized in the bushing huh?

 

yeah on all 4 bushings the sleve around the bolts are seized so i have to destroy the bushing and the bolt to get the leaf springs out. i dont know if this has happened to anyone else but its one of the biggest pain in my ***** ive ever experienced when it comes to what i thought was going to be a simple mod. but what can i expect its never is as easy as you first assume.. im going to post pictures of the complete job when im finished. hopefully by the end of thanksgiving break. my pocket book it empty by the time this is done.

 

I had that happen to both of my front leaf spring bushings. I had to slice through the leaf spring to get em off. PITA it is.....and that's when I bought a BIG can of anti-seize. Now the bolts come out so easily.

 

given the proper prep to replace rear springs, you'll get them out w/o replacing the bushings, and w/o wrecking the nut inside.


it should take an hour per side on the front bushings to get them out properly.

if you just go at it to pull the front leaf bolts out, you'll either break the bolts, or break the nut loose inside the frame rail...that's no good.

 

Please explain.
