Rear bump stops are need to keep the rear shocks from bottoming out on themselves and damaging the cylinders.
The best way to set up rear bump stops is to remove the springs and attach the shocks and then jack up the rear axle till the shocks bottom out. Then measure the distance between the factory bump stop and the bump stop pad. You need to fill the gap plus 1/2" to 3/4" to keep the momentum of the compression of the suspension from bottoming out the shock. So if the gap from the factory bump stop and the bump stop pad is 2" mount a 2.75" bump stop on the factory bump stop pad to hit the factory bump stop. This will keep the shock from hitting its self and destroying the cylinder internally.
Got some useful info from our Hunter Alignment Machine guy about ESP and alignments. This applies to all ESP equipped vehicles and not just Jeeps. If you have a alignment and toe adjustments are required and you have ESP the steering angle sensor must be adjusted or unusual ESP operation can result, not always but sometimes you can get unwanted operation. Come Jan 1st 2012 every vehicle sold in the US must have ESP as standard equipment, and all Jeeps have it standard as of 2006.There has been some reports of unwanted operation of ESP that has caused some issues. As of this month every Firestone(nationwide) will have the ability to reset most steering angle sensors, not all but most and the ones that cannot be done must be reset at a dealership as they require there specific scanners. Some vehicles will require the battery to be disconnected for the reset and a "battery saver" cannot be used to save stuff like radio memory or the reset will not work so if your vehicle has a "anti-theft" radio that requires a code to unlock make sure you have that code ready as we will not be responsible for the added cost from a trip to the dealership to unlock the radio as we must reset the steering angle sensor if we are able to do so. They also may deny doing a alignment if they cannot reset the steering angle sensor, even if you have already purchased a lifetime alignment package (you should be refunded the cost).
THAT'S WHAT IS CAUSING A LOT OF ISSUES WITH THE ESP EQUIPPED VEHICLES.
You need a front-end alignment after installing upper control arms, front springs or front struts.
JBA STD Toyota UCAs for the Tacoma, 4Runner & FJ Cruiser VS JBA HD Toyota UCAs for the Tacoma, 4Runner & FJ Cruiser
First I will start with the STD (standard duty) a-arms, they were designed for the weekend worrier who worked hard all week and wants to play hard on the weekends with his Toyota. The JBA UCAs will give you 1" extra down travel on the front suspension with more ball joint travel and strut spring clearance.
JBA STD Toyota a-arm
The JBA STD A-arm tubing is 5/32" wall and 1" dia. with a Moog style K6292 ball joint. On the JBA HD (heavy duty) A-arms are thicker tubing, with 3/16" wall and 1-5/16" dia with 11ga guests on the bushing bongs. The HD a-arms are for more extreme offroad abuse like offroad racing, rock crawling and dune jumping.
JBA HD Toyota a-arm
Both STD & HD will work with the Fox extended travel coilovers and the JBA Coilovers.
If your steering knuckle is reinforced get the JBA HD a-arms.
If you jump your Toyota you need the HD a-arms, If your steering knuckle is reinforced with a weld on gusset you need the HD a-arms.
The Ball joint range of motion
Up travel is 40 deg off of center line of the ball joint, down travel is 50 deg off of center line. Full range of motion is 90 deg. Note: you will not get that kind of extreme travel with a uni-ball joint
More spring clearance is
More suspension travel
More articulation, See JBA vs Uniball
More traction on the trails
JBA UCAs give you MORE for your money!!
In conclusion the JBA STD a-arms are for a daily driver/weekend worrier the JBA HD a-arms are for extreme offroad use.

At JBA we make the original after market upper control arms (UCA) or A-arms for the Jeep Liberty (KJ), we designed them better than Chrysler.
Now, I know you're probably skeptical. That's normal and healthy. Let me give you three good reasons we can back up what we claim:
Three Reasons To Believe What I Say
Reason one: Al Handy designed and built the first set of upper control arms (UCA) or a-arms in 2003! JBA first generation a-arms were born, we are now making the gen 4.5 our best design to date. There are hundreds of Jeepin by Al's a-arms in service all over the word.
Reason two: I have been designing and fabricating custom product for over 20 years.
Reason three: JBA a-arms are approved by All J Products, Rocklizards Fabrication and Jeff Daniels Jeep Customizing.
Here is a summary of the benefits you receive with Al's upper control arms!
3/8 inch more strut clearance than the factory a-arms
Ball joints are mounted on an angle to line up with steering knuckle
Replaceable ball joints
You can replace the ball joint for under $35.00 per control arm
Our A-arms work with all lift kits on the market today
Three styles of control arms size fits all!
Factory front end alignment
Red powder coat finish
Heavy duty tubing
CNC manufactured parts
Manufactured in USA
Now, you're probably wondering how and why we can do all those things.
Let me explain.
The JBA Upper A-Arms were designed for your lifted Liberty and will directly replace your stock (UCA) upper control a-arms. The original equipment a-arm hits the spring, which causes premature ball joint failure on Liberty's with a lift kit. The JBA A-Arms are compatible with all the lift kits on the market today! These A-Arms were designed to fit on 2002 through 2007 Jeep Liberty's. (Now 07 KA & 08 KK) Made of heavy duty tubing, red powder coat finish, with Spicer HD replaceable ball joints and factory rubber bushings. The A arms are assembled and ready to bolt onto your Liberty. Sold as a set, 1 left & 1 right upper control arm (UCA).
Don't take my word for it.

Testimonial: Hello JBA
I just wanted to take a moment to thank you for outstanding product and service. I have had the opportunity to deal with your competition prior to buying my JBA uca's. With those arms installed, my camber was at +1.6 degrees. This was after 3 trips to 2 alignment shops. After many emails because the owner obviously has no voice they finally took them back. Also they informed me that the problem was my installation or setup. Not possible that the arms could be messed up. The installation of your competitions arms it took some persuading to get them to go in. Also when installed they squeaked like crazy!
When I installed my JBA’s they went in like they were made to fit and one trip to the alignment shop is all it took for a perfect alignment. I have always been one to root for the underdog but, sometimes there is a reason why they are the underdog.
Testimonial: Thank you Marlin, Just a note to let you know that I have had the a arms and 3.5 " lift kit on for about a week now, and think that they are great. The jeep rides great and looks really good. I am very glad that I went with your a arms. Plus the service was outstanding! Ordered on a Fri and received on Mon. To any one who reads this, if you have a Jeep Liberty and want to lift it make sure u use Als A Arms.
Testimonial: JBA, Just wanted to let you guys know I received the KJ upper control arms and put them on today. The arms installed fairly easy as I was expecting it to be an all day project. All contact I previously experienced with the ball joint/strut is gone now. Your Gen 4.5 arms have solved the problem I have lived with for a long time. I installed the lift shortly after buying my KJ new back in 02. The noise from the contact issue was very noticeable from the beginning. After having that issue I was concerned about even buying any other aftermarket products for the Jeep, including yours. Problem was once the lift and tires were on the vehicle there was no way I would be removing them, it just looked way too nice. Besides I have yet to see any other lifted Liberty's where I live. Your arms have taken away the concern I have had about imminent ball joint failure from being a reality. I just wanted to thank you for a making a great product that worked great for me.
James Parker Newark, OH
Testimonial: They've held up great to all the wheeling I've done on them since they were installed at All-Js on May 24 2008. The arms have held up to Hell's Revenge, Fins $ Things, Porcupine Rim, Lockhart Basin/Hurrah Pass, Long Canyon Road and the White Rim Trail in Canyonlands National Park. Not to mention Big Eye Mine Road, a local trail here in Yuma, AZ.
I think they've had nearly the same off-road miles as on-road miles since being installed. With these arms matched up with the Frankenlift Premium II kit, it makes a KJ feel like a street car in ride feel, but WAY more capable off-road. I love it!!!
Thanks for a great product!!!

This design has been in my head for many years. When I got a phone call from Nathan he wanted a long arm suspension on his Jeep Liberty KK. After talking with Nathan I started putting my design in Auto-cad Inventor. It started to take shape!!
JBA long arms build on a Jeep Liberty
JBA long arms build on a Jeep Liberty
Nathans Jeep was driven from Texas to PA and arrived on January 17, 2016.
Nathan's KK Before
Parts used on the build
4) ORI struts 14" long
Currie IFS center diff, Ford 9" with 5:13 gears
RCV custom CV axles
Howe Performance power steering pump, reservoir and cooler
Grand Cherokee (WK) parts
front bearing hubs
cut down steering knuckles
tie rod ends
Chevy suburban string box & Idle arm
The rear is a Dana 44 out of a JK with factory electric locker and 5:13 gears. We built a custom 3 link mount, to do this we had to remove the fuel tank, muffler and exhaust system. The fuel tank is an modified fuel tank from an old Wrangler. We mounted the fuel tank were the spare tire was mounted from factory.
We started the build by clocking the transfer case to center the front drive shaft. We built a 10" cradle drop to hold the steering box and the Currie diff. The control arms are about 10" longer then the factory a-arms and mounted to the cradle.
Warning!! Do you have the factory Chrysler upper control arms on your Jeep Liberty?
I want to notify my customers and owners of the KJ Jeeps (Jeep Liberty)
If your Jeep is lifted and has over size tires, You may be at risk of losing a front tire!! In these failures the ball joint separated from the factory Chrysler upper a-arm. Please check your ball joints!!
