Control Your Control Arm Flex. Improve your Mustang's straight line acceleration and cornering grip at the same time with these Extreme Joint Mustang Lower Control Arms from J&M. With your stock lower control arms, the exceptionally soft OEM rubber bushings insure your control arms don't bind, preventing undesirable handling characteristics like snap oversteer. However, if you try to accelerate or stop quickly in your 2005 - 2012 V6, GT or GT500 Mustang and you're likely to experience wheel hop or rear end instability. Control your control arm flex with J&M's Extreme Joint Mustang Lower Control arms and go faster - everywhere.

Better Handling. With J&M's exclusive design, you get the benefits of a rigid bushing, resulting in better straight-line grip, but the performance of a spherical bearing under cornering, so you get the best of both worlds. The exclusive design of these lower control arms features a steel inner ball surrounded by polyurethane outer cups. The result is great traction during straight-line acceleration, and bind-free performance during spirited cornering for predictable grip.

Quality. Though harder to work with, J&M selected round tubing for its superior strength and resilience to bending and torsion when compared with rectangular or square tubing, while also being lighter. With an offset design to guarantee bind free geometry, these lower control arms are the perfect suspension upgrade to your 05-14 V6, 05-14 GT or 07-12 GT500 Mustang.

Would this effect the traction control in adverse conditions? I'm sure this is a stupid question but my 2012 5.0 with 3.73 gears has entirely to much wheel spin but living in Alaska when I push the magic button during winter snow (traction control) the car is simply amazing. Was just wondering if this product would hurt that?

  • No. This product is designed to keep your axle planted to prevent wheel hop. The axle ultimately is more stable, slightly improving traction. Should have no negative effects on your car.

Relocation after lowering? Once I have these on my car when I decide to add lowering springs in the future will I need to use a relocation bracket for these?

    A+++ great product

    These lca's are perfect the money. Eliminated wheel hop and keeps the end grounded for better traction! I am 100% satisfied with product and recommend for anyone looking to improve launches and hard cornering.

    No more wheel hop!

    (NOTE): These are just as good as the expensive ones-very solid and Energy Suspension bushings. Install was quick (Get new bolts & nuts from Ford). Down to the dirty...When people say wheel hop, they also mean when you take a corner and the rear bounces out over a bump. You know the drill; lifting on the throttle around a bumpy corner so the end doesn't bounce around and slide out. These will cure most of that issue if not all of it. First test drive and I had none of that issue anymore. The car became very predictable and I no longer braced over bumps. Rear end is more controlled and because of that, my grip increased.

    One drive will make you a believer!

    Here in metro Detroit there are lots of terrible roads that would make the rear end of my 2005 GT hop and shudder like a clumsy piece of junk when I tried to drive fast over them. Well, my first drive after installing these control arms was a revelation. I immediately headed for a really bad section of road to see how they would do, and was amazed. The rear end stayed planted over all but the biggest bumps and broken sections, and even then it only hopped a little bit. Hard launches were a breeze, with no more hopping or shuddering just wheelspin! Because the rear suspension is so much tighter and more precise it makes the whole car drive better. Handling feels much sharper with the vague feeling from the axle gone - I really felt the difference when taking on-ramps! I honestly can't think of any negatives to these control arms. They ride nicely and are very quiet, and can be installed in less than 2 hours if you have someone to help you. Bottom line - if you still have stock lower control arms on your car, spend the $175 and get these. Beg, borrow or steal if you have to, you will not be disappointed!

    The Perfect LCAs

    I had some hope that these LCAs would help with the traction issues, and it helped big time. My launches before were a "squat and go", but after the installation, there is little "squat" and a lot of "go". I have to mention that the passenger-side LCA gave me and a friend of mine the hardest time - it didn't line up with the bracket on the chassis. I needed 3 people to push the entire rear assembly forward just to have someone put the bolt in. Other than that, I'm very happy with these LCAs. There's no comparing these LCAs to the stock ones.

    Throw away your stock Lower Controle arms

    These control arms function better than I ever thought possible. The car is smother , corners better and accellerates better. The squeeks went away now that the suspension can work without binding or flexing the stock control arms. The instructions had pictures and not all the references in the text appeared to align with the pictures but if you do what the picture shows you will be able to install these in about an hour.

    EXCELLENT Prouct!

    This is a must if you lowered your car at all. Before installing I noticed more noise and a mild clunk in th back, but after installing these everything is much quieter and smoother.

    Hop-B-Gone

    I really loved putting these control arms on my Stang, i did go to Ford and buy new bolts and nuts I really suggest doing so the rear bolts looked fine however the front bolts has some marks on the threads. The new arms fit perfectly and once I got driving I tried a few launches and it was amazing how much of a difference there was while i still have alot of wheel spin it stayed planted and gripped up much sooner. Cornering is much tighter and feels much more confident. I am very happy and really recommend these to anyone looking to get a great lower control arm with a lube point. Oh, that reminds me the energy suspension bushings that come with them are fantastic.

    J&M lower control arms

    If you want to improve the traction and handling without putting new springs and shocks on your car then i recommend the J&M extreme control arms. Why? because the amount of sway that the stock arms give is terrifying in the corners, and the amount of wheel hop is annoying while accelerating but with the J&M you have no sway, so much more confidence in the corners and no more wheel hop. Installation is easy part from the parking brake cable goes through the old control arms so disassemble takes some time. For guys who like to show their stang the corners at much higher speeds without spinning out you have to get the J&M Extreme!!!
