Default Which budget boost? rake? death wobble?

I am torn betweeen a bunch of bb's. I want a 2" dont know if to go with the skyjacker, RE, TF leveling kit, etc etc what distinguishes each one bc they all look the same to me. Im just looking to put 33inch.

I would like to get rid of the factory rake.

Does putting a BB cause the death wobble?

Thanks for all the help guys.

with this lift rides like stock http://roughcountry.com/jeep_jk_2.html get the shocks if off-roading...
You might be ok with just a body lift for 33" tires, then you won't have to touch the suspension... http://roughcountry.com/jeep_xtras_jk-body-lift.html

From your list I would look towards the RE kit with the new shocks. The RE kit will remove the rake and the replacement shocks are valved better and have more travel than stock. Otherwise there is little difference amongst BB kits. I spent a little more and went with an OME 2" (616/617) coil kit which is really a nice ride although it is a bit taller than 2" lift.

Death wobble isn't caused by lift, usually it is caused by failing to properly install the track bar, but it can also be caused by damaged suspension components as well. Very few people wind up with death wobble, I wouldn't worry with a 2" lift. If you are mechanically inclined, do the install yourself, just make sure you have a good torque wrench, you don't want to guess. Either way, retorque the fasteners every 100 miles until they no longer change. They can and usually do loosen a little.

Good luck,
John

If your just talking about spacers, It wont lead to any death wobble. You only have to remove the lower shock bolt and the lower sway bar link bolt to drop the axle, remove the spring and slip in the hockey puck...then torque it up and go...then torque it again after a hundred miles or so

My everyday driver is a 2005 TJ Wrangler X, and I didn’t feel I needed a monster truck so I decided to go with 30-31" tires instead of the 27" that came on my TJ. To accommodate the larger tires, I was going to need to get a couple of inches more clearance for the tires. I ended up installing a set of 2 inch coil spring spacers to lift my ride height slightly. After I installed the spacers, I re-set the toe to 1/8" and drove the jeep. It felt slightly unstable, but I knew I tightened everything back up to spec. I did not rotate, or balance my tires. Nothing else was changed. I drove my Jeep locally for the next few days to work and back (only 4 miles per day round trip). The steering wheel was centered and the jeep tracked straight.
The next weekend I drove to Sacramento to visit family. When I reached a crappy rough highway (HWY 80) the front end felt wobbly. As I approached 40-45 MPH and I hit a bump on the right front, I got the sensation I was driving on triangle shaped front tires that were out of sync. My garage door opener and other crap on the dash leapt off onto the floor and my butt puckered! Scared the hell out of me. I slowed and it went away as I came to a stop. Every time I tried to go over 40 MPH the wobble came back with a vengeance. I ended up taking surface streets (keeping the speed under 40), until I found a much smoother roadway to take home. Once I was on a new stretch of Highway (N/B 99), I was finally able to get up to 70 MPH w/o wobble. Drove the rest of the way home worried I might die, but it drove fairly normal.
The next few days, I searched the internet as many of you have I’m sure. After reading all the posts available, I started inspecting my jeeps front end. After 2 days of intense scrutiny of all the components, I came to the conclusion, nothing was worn, loose or broken. What the hell???
I decided to purchase a magnetic base angle gauge ($5.00). I used it to check the angle of my CASTER and found it was over 3 degrees above spec. (top ball joint farther back than lower ball joint total of almost 11 degrees from zero). I ended up re-setting my CASTER back to 7 degrees and re-set my toe again to 1/8". Guess what? my wobble went away immediately. Over the next few weeks, I put about 700 miles on it with everything in place as it was with the wobble. I even drove the same stretch of highway 80 several times to make sure the wobble was gone. I felt confident the disease was cured, so then I bought my new tires and rims. Now with an additional 2200 miles on the new tires, I know I beat it.
I’m not trying to say that all of you with Death Wobble (or what you think is DW) can decrease your CASTER and fix all your woes… What I am saying is it DID fix mine.
I know that some of you will not believe this, but if you think about how a shopping cart with a bent caster wheel reacts when pushed forward, our DW does virtually the same thing. Think about how CASTER angle works, if you had lets say 45 degrees of positive Caster, your wheels would probably wobble at 10 MPH just by going over small pebbles. Anyhow, if anyone has questions, don’t hesitate to ask. For those skeptics out there, keep spending money on parts instead of thinking outside the box. I fixed my DW for about $10.00, how much have you spent trying to fix yours?
Oh.. and before anyone asks...
NO, I did not replace my steering stabilizer, shock, dampener or whatever you want to call it.
As long as your alignment is set up right, there is NO NEED for one.
No other parts were replaced or tightened. All I did was re-set the CASTER back to about +7 degrees.


SO... to answere your specific question..."Does putting a BB cause the death wobble?",
YES IT CERTAINLY DID CAUSE DW IN MY 2005 WRANGLER.

I know the perfect solution for you. Teraflex just came out with a leveling kit that gives you 2" front and 1" rear. It will level your jeep, without any major changes to your suspension or drivtrain. The best part is you can run up to a 34" tire and it only costs $130. Plus Teraflex is active on the site, and Joe has awesome cust. support.

Here is a link to info on the kit: https://www.jk-forum.com/forums/sponsoring-manufacturers-vendors-check-out-cyber-monday-specials-24/new-teraflex-jk-leveling-kit-%24129-99-a-78780/
