  • Why Rear Bump Stops

    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.

  • ESP Reset after a front-end alignment

    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).


    You need a front-end alignment after installing upper control arms, front springs or front struts.

    Get the ORIGINAL after market upper control arms

    JBA A arms!

    Dear Friend,

    If you'd like replaceable ball joints, grease able ball joints, heavy duty construction and welded by certified welders, then this might be the most important web page you'll ever read.

    Here's why:

    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.
    Listen to what our customers say.

    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.

    Thanks again
    Brian Short

    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.

    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!!!
