    Fixed Length. The JKS Fixed Length Front Lower Control Arms are designed to provide superior strength. They mount directly to your factory control arm mounts and can be used with either OEM upper arms or with JKS's Adjustable Uppers (sold separately) for precise adjustments and impressive strength. These Lower Control Arms are 3/8 inch longer than stock, and will increase and help correct caster for Wranglers with 0-4.5 inches of suspension lift. They're suitable for the daily driver and off road enthusiast alike thanks to quiet riding rubber bushings.

    Durable Construction. Designed to take on the rigors of off road abuse, these Lower Control Arms are crafted from 2" x 1/4" wall DOM tubing and are formed to match the factory arm profile for reliable tire clearance. Each arm is equipped with Clevite® brand rubber bushings to provide a quiet ride and minimize vibrations. They're completed in a tough black powder coat finish to prevent corrosive wear.

    Bolt-On Installation. These Front Lower Control Arms feature a bolt-on installation. They're specifically engineered to work with factory control arm mounts and shouldn't be used in conjunction with other control arm relocation brackets or mounts.

    Application. The JKS Fixed Length Front Lower Control Arms are designed for installation on all 2007-2018 Jeep Wrangler JK and JK Unlimited models equipped with 0-4.5 inches of suspension lift installed.

    I have these in my 4in lift. My caster is a bit on the high end. Will adjustable upper control arms adjust the caster closer to stock specs 4-4.5. I am experiencing swerving at highway speed this was occurring before these fixed CAs and I have done everything suspension. The only thing I can think of is going with upper front adjustable CAs. How should I adjust the upper to bring the caster a bit lower as it is too high? Thank you. I love them they look great.

    I have a 3.5" lift I am running relocation brackets to correct caster angle with stock arms. Will I have to run these with the brackets or get rid of the brackets and install these into stock eyelets on axle and frame?


    • The JKS Fixed Length Front Lower Control Arms would replace both your relocation brackets and stock arms.

      One Hand on the Wheel

      I have a 4" lift with 35s. I felt like I was all over the road and needed 2 hands on the wheel at all times. Since I installed the JKS fixed control arms I am comfortable now driving with one hand on the wheel. These control arms were easy to install and corrected my caster. Extreme Terrain made sure I had them fast.

      Wow, it rides amazing. I can easily tell a difference between the old and new. It rides so smooth and take potholes like they aren't even there. Only gave it 4 stars because the install instructions didn't tell you everything you would need for the job.

      Great Product

      These control arms are built to last. They are definitely stronger than the stock arms. The extended length works perfect with my lifted Jeep. Easy install with the included instructions.

      Love them

      I purchased these to add with my J - Control 3.5 lift. Because my experience is the factory ones are not strong enough for off-road. These are made great and exceeded my expectations. However if you they are not adjustable but my lift has brackets that allow you to use these.

      JKS Fixed length lower arms

      Great product! They follow the factory bends so tire clearance is a non issue, They are slightly longer than the factory arms, so after installing my 2" lift, they corrected the front caster so I didn't have to use the eccentric adjusters supplied with the mopar lift. They also are quite a bit beefier than the factory arms! Simple installation and no maintenance required

      fixed lower control arms for jeep jk 08'

      I put these on with ease and made a big difference. they put my caster back to 4 -5 degrees which helped the wondering steering at highway speeds. I have a 3 inch lift with 35'. great product if your lift doesn't come with adjustable lower control arms.
