    Improves Handling. J&M's street tuned rear lower control arms will help keep your Mustang's rear end planted even under high RPM launches. Their exclusive design eliminates undesirable handling characteristics of the S197 suspension without compromising on cornering.

    Better Than Stock. Due to issues with suspension design, your stock bushings are very soft, which can cause wheel hop during hard braking or acceleration. The J&M Rear Lower Control Arms offers a patented bushing design that eliminates wheel hop and improves straight line grip.

    Better Than the Competition. Unlike other products, the J&M Rear Lower Control Arms have a unique design which combines the straight-line performance benefits of a hard bushing with the handling benefits of a soft bushing.

    Premium Quality. Made from round tubing for strength and finished with a black powdercoat for durability and good looks, the J&M Rear Lower Control arms are perfect for any street or strip driven 'Stang. And these arms are made to the same tolerances as their race performance arms to assure a perfect fit and long life. And J&M backs their bushings with a lifetime warranty for peace of mind.

    Mine have rubber bushings how to do i go about getting ploy bushing for the set I already have?

    • I recommend shopping around online for polyurethane bushings for your stock control arms. The J&M Rear Lower Control Arms kit comes with 4 polyurethane bushings, 4 cupped polyurethane bushings, and 2 polyurethane inner balls. If you are looking to upgrade both your Control Arms and bushings, this is the kit for you.

    Are these recommended for a lowered ride? Going to be lowing my ride soon 1.4" nearly and adding shocks/struts. My car isn't completely a daily driver nor does it ever see the track. Should I install a pair of these LCA and the UCA as well with the springs and dampers?

    • I absolutely recommend these control arms, and especially if your car is lowered. I have my 05 V6 Convertible lowered 2 inches, and before I put these on, my rear end was noticeable loose. After I installed them, the rear end had far more directional stability and it would keep the car better planted to the pavement while cornering. On and off ramps can now be taken at higher speeds, subject to tire condition of coarse. If you are lowering your car, I would also recommend getting Rear Lower Control Arm Relocation Brackets. In order for the Lower Control Arm to do what it is designed for, it needs to have a slight downward angle going toward the rear. This will accomplish that. They're available here as well and you'll down in the rear end anyway, so might as well do it all at once. And. yes to everything else you asked.

    Hardware included? Will everything I need for the install included? If not what do I need to get along with these lower control arms?

    • Nothing else is required to install these. You the arms are complete and you will just simply reuse the stock bolts to install.

    Will these help with 4.10 gears? I have 4.10 gears along with a lot of other mods and my car has a hard time getting traction off the line, I usually float and go to the left and don't get traction till the end of 2nd or beginning of 3rd. Would these help me get better traction off the line and stay in a straight line?

    • I have these and I think they are great! They will help your launch because of the harder bushings over stock there is no play with these and will also almost completely eliminate wheel hop, enjoy

      Solid feel with a little extra noise

      These eliminated the wheel hop from the stock arms and really makes the rear end feel a lot more planted. There is a bit more noise unfortunately, and just a slightly rougher ride. I would say the noise is more noticeable than the firmness.

      Easy to install. Simple design and works great. Had a squeak on rear right side. Could not figure out what it was for the longest time. Finally narrowed it down to the lower control arm. Squeak is gone!

      Wheel hop gone!

      Installed these by myself in under 2 hours with a jack and jackstands. Its very easy dont be afraid to make the leap even if you've never changed out control arms. I read the reviews where it said a second person is required. Not so, a helper would have been bored to tears. Pairs nicely with a panhard bar!

      nice quality

      I installed the JandM Lower Control arms along with JandM Upper Adjustable and JandM Upper control Arm Bracket. While I did not weigh them they were significantly lighter than the Food Racing lower control arm I took off. Installation was straight forward, lift the car, support the rear, unbolt the old one install the new. As for noise, there is a slight increase in transferred noise but not that bad. My wheel hop issues do seem to be gone(installed the upper as wheel) after some hard launches and some "spirited driving" and the back of the car does feel tighter. as far as time to install, I was doing both upper and lower and the bracket, the gas tank had to be lowered to get the bracket fully out, I did have help and worked in a shop with out a lift on jack stands. total time for everything was about 3.5 hours for us, working on the floor and we were both experienced auto techs, just the lowers I would estimate I could do those in approximately 1.5 hours, nothing real hard just tedious work. Overall, they do seem to be a good product, saved some weight, Quality built, performed as expected.

      Love these things on my 2014 manual 3.7

      I have done research on control arms, and JandM are known for great suspension products on the mustang. I saw where a lot of guys put these arms on their GT500s, the ones specifically were 2008s, and they loved them and had no troubles with them at all....so I could imagine what they would do for the 2011-2014 5.0s! I mainly got these because these have a 50/50, or really a 100/100 focus on performance and drivability. But I know you all are wanting to know, so here it is-YES, this does eliminate wheel hop! I like to come out hard from side roads or a driveway to quickly catch up in traffic, and I barely chirp, once in a while, when I gun it! Before, when I did this, I would always spin tires and have to let go to regain traction. Now, they hook up and go. In a straight line or when driving, they are beast! These put the power to the ground consistently. Also, when I am shifting hard, the car doesn't jerk (when the front goes up then down) near as much as it used to. I would say about 80 of the jerk is gone now! Now, the other half of it-I usually am driving 80 miles a day, with half of that on country back roads, and then the other half on the rough construction roads of I-40 in Raleigh, NC (My Raleigh folks know what I'm talking about (2016)). So what this means is, I am driving through ruts (where asphalt is scraped down to the old concrete road), bumps, bridges, and rough roads. I was afraid of the control arms being too stiff, and these roads tearing up my rear end and suspension with stiffer arms, but that is where these spherical bearings come into play. Don't be afraid of them-they don't work like full spherical-ended control arms, but they allow the arm to have a little flex room, while yet being very stiff-my ride is so smooth! Yes it is stiffer, but the car doesn't bounce like it used too-it absorbs the road so that it keeps the wheels planted, while keeping the chassis riding smooth and stiff as well. These arms do not jerk you around in the car. They transfer the same amount of road noise as the stock arms, so it's not much at all. They are maintenance free also, which is good, because a lot of 3.7 specific control arms have grease nipples and have to be re-greased so often-these come with the marine grease needed, and once they're in, they're in, no troubles or maintenance at all. Overall, I am VERY pleased with these, and can't wait to start going to a 1/4 mile drag to see how these do. I've had them for a few weeks and it still is working well. I plan to come back and post after a year. My mods are not much-just an AIRRAID CAI and hurst shifter from AM, and then a BBK 73mm throttle body. I still have stock wheels, rims, suspension/everything else. These definitely have made the difference, and I suggest them for everyone! If you want a good ride and great traction, these are the way to go. Thank you AM for keeping the July 4th sale one day longer than everyone else-that one day literally made the difference! I had been looking at these and was trying to get the money ready for it, and that one day made the difference. They shipped it to me pretty quickly and it came in no time. Great pricing and great quality. I am also glad the mustang has great working ergonmics-installation was simple, but took 3 hours-that's from start to finish-literally trying to position the jack in place and then dropping the car after we torqued it down while under load in the air. We also had trouble with our tools and were taking our time. the 129 ft lbs was a bear to do, but with the right torque wrench, you can do it much easier.

      Great LCAs that absolutely got rid of the ridiculous wheel hop of the stang. Perfect fit and high quality material. Installation is a bit tricky but having a second set of hands is necessary.

      Exactly what you need.

      Installation was strait forward. Instructions are provided. I would use nitrile or latex gloves next time. The lubrication provided is tough to get off your hands. You will notice an immediate difference in the mannerisms of your rear axel. It is much tighter and the power is instantly directed to your wheels. Take off feels much faster, the wheels spin but you don't notice any hop. I replaced my original rear LCA's because they were squeaking terribly, which makes the new ones well worth the money, however, the additional benifits are what make this product a must have purchase. Two weeks in no squeaks. If you are driving this car on a daily basis and don't have it at the track or AX course every weekend, you should seriously consider this rear LCA. Install of the LCA's only took a little over an hour with set up and prep. This product will not solve all your handeling issues which is why it got 4 instead of 5 stars. For what it is though its a great part. I had no issues with fitment and I was able to put it into place by hand. Personally, recommend reading directions first to save time, also look on the forums for any additional tips on how to do the work. One tool I would add just incase you don't have an extra set of hand is a ratchet strap to help allign the holes while you slip the bolts in. I did install these at the same time as the Koni STR.T Orange shocks and struts. So far proving to be a good Combo and you wouldn't believe you were driving a 10 year old car.

      good part, but just FYI

      Great part. No issues except mine does transmit a whirring sound between 65-80 mph (highway speeds). After some research it just seems that its normal for this tubular type of lca with the new bushings. I know... it's a mustang; who cares, but just fyi for anyone who dd and notices these things.

      First timers should read this for a clean install.

      First i would like to start out with this is not a review yet. This is a first timers installation instructions. I plan on reviewing the actual part when the weather is better in my area (northern united states) Now to installation, First off if you are doing this in your driveway or back yard plan for about 3ish hours (took me 3.5 but i also did it in a snow covered parking slab). You will need TWO PEOPLE FOR A SMOOTH INSTALL. The directions that JandM provide are alright but just need some clarification. Now you have your wheels off with a load free suspension _remove parking brake cable. - loosen front and rear bolts on the stock control arm - (here's were your second pair of hands comes in) apply forward pressure on your axle to allow easy removal of the front bolt. -remove second bolt and to take out the factory control arm. JandM assembly rather straight forward grease bushing before placing them in the actual control arm But the rear bushing have this plastic ball bushing that gets sandwiched between the rubber bushings. To get the ball bushing into place you will need a rubber mallet. after greasing the ball GENTLY tap it down into the control arm sleeve, make sure the hole in the ball is facing out so it lines up with the rubber bushing that go on the ends. Now the rubber bushings on the rear portion of the control arm are going to stick out. That is because they are an interference fit on your s197. lubricate the faces of the rear bushing to allow for easy placement on your axles mounting bracket. start the bolt through the rear bushing so the arm can hinge up and down. (now person number two) push forward on the axle again so (person number one) can easily reinstall the stock bolt through the front mount of the control arm. tighten everything back down as best as you can. Reattach your parking brake assembly *note* you dont have a hole in your new control arm to put the line through like the stock assembly the directions will have you zip tie down your parking brake cable to the control arm. I suggest you go to your local harbor freight or whatever big hardware store you prefer and purchase some heavy duty zip ties. Take a breath we're almost there. Ford specs say you need to torque the control arms down to 129lbs. You must do this on a LOADED SUSPENSION. To easily load your suspension move your jack stands to the axle so the vehicles weight will now rest on the suspension once more. make sure you stang is high enough to allow you to get a good grip on your torque wrench. If you cant seem to get your torque wrench to click i suggest that person number two lend a helping hand, yes it is awkward but i would rather have a torqued suspension that my personal space for 30 seconds. congrats you just installed your new JandM control arms. Now go shred some rubber!

      Awesome product!

      This product took me by myself with a lift right at an hour to install. Let's just say I have been using the factory control arms long enough I was used to and almost unaware of how bad my traction loss was and with 4.10 gearing 1st gear was practically useless. Well now that's in the past because these babies really plant the rear end, probably rated up there with the best mods I have installed. They're worth every penny so don't hesitate!
