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.

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?


  • These control arms do allow you to get better off the line traction by helping to eliminate wheel hop. I have these on my 05 and they are great

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.

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.

    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 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.

    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!

    J&M Rear Lower Control Arms

    I love the new rear lower control arms they are awesome. Before with the stock ones if I rodded on the car from a stop I got really bad axle hop and had issues planting/launching, after installing the new J&M rear lower control arms the car no longer had axle hop from hard take offs(awesome) and had amazing take off and launches off the line. I also found that the car had much better feel going through corners fast It felt more planted and "in control" and even excelerating through corners is much better. Amazing product, easy install and wicked results and the parts were so cheap. Great buy, really great bang for your buck!

    J&M LCA install

    Install was straight forward and fairly easy on jack stands w/hand tools. Great price and fast shipping. Now, my .02 on this install: LCA's should come with hardware since factory stuff is "recommended one time use". Prices for new factory nuts and bolts have increased - Expect to pay about $60 for all hardware. Oh, and you have to buy 4 of the front LCA bolts - They only come in a package of four, & you only need two not four - Thanks, Ford... In my case, I also installed CHE anti-squat brackets and the rear LCA bolts aren't quite long enough to have any threads showing out of the lock nut, so I went with M14X110 10.9 bolts, washers and lock nuts for the rear and I used new factory stuff on the front with loc-tite applied all around as well.

    Great product! The control arms are very well made. Install took about 2 hours, but that was with me using jack/jack stands and really taking my time. The bushings are very tight and a little hard to get them in. So far no wheel hop anymore! great deal for the price.

    Goodbye evil squirrels!

    My poor pony has reached 50K miles finally and small things are going here and there. This summer though, I noticed on my 06 GT there was a small squeaking coming from my trunk area. Mostly when the car shifted, hit a bump, or came up to a stop. It sounded like a squirrel was in my trunk! I read in the forums that the bushings in the lower control arms go pretty quick. I ordered these, and added my own grease fittings at work. Took me and my buddy about an hour and a half to install, but it was rather easy. The squeak is gone, and so is the hop between hard shifts. Great product and highly recommended!

    J&M Lower rear control arms

    easy install, all you need is a 1/2 inch drive 18 mm socket, some lock tight, a jack and two jack stands. you can do this in about an hour. you do have to pull the rear forward to get the second bolt in. a 2X4 works great. I drop the clutch at 4 grand and she hooked up nicely.

    A lot less wheel hop

    Immediately after installing the J&M lower control arms I noticed the rear end of the car was felt tight and planted. I did a couple WOT runs and I am happy to say the wheel hop is gone. the only time it wheel hops now is when it is extremely cold out. I am very happy with these lower control arms and would definitely recommend these to anyone with a 2011+ GT. It's the most bang for your buck

    Install was a little harder than expected

    Im a fairly good shadetree mechanic. Took about 3 hours to install these by myself. Removal of stock was piece of cake. Installing I ended up using a large tie down to pull the axle into place (pulling it forward on drvrs side) like a come along so the bolt holes would align. Same thing on passenger side but also had to employ crow bar for leverage. Folks who installed in 45 mins, Im happy for them, but my install wasnt so easy! That being said, the performance of the LCA's is great. No wheel hop at all now on the street and it feels smoother, noise from stock bushings eliminated, and solid launches. Flying solo it took 3 hours but havent a second person would have likely cut this in half very easily.

    Worth the Money

    I was on the fence about buying these LCAs for a while, they went on sale and I snatched them up. Took about 3 hours to install with jacks/jack stands and a few beers throughout. The bolts were a PITA to torque down but persistence will get you there. Just make sure you block the front wheels...otherwise the car might roll a couple inches and cause the rearend to shift when the first bolt is pulled out (oops). The car definitely feels different, nothing huge but I would consider it to be $100 worth of improvement. Downside: road noise is slightly increased but it's nothing major. I have noticed though that the car is jumpier on rough pavement but I guess that is to be expected with stiffer suspension.

    Overall a good buy, install is a breeze and wheel hop was greatly reduced. The control arms came in black so I painted them red to be a little bit more noticeable. The bushings look to be much better quality over stock too. I would recommend to anyone needing a new set of control arms!

    Simple install and I have no previous mechanic experience besides changing my oil. The difference between these and the stock ones is night and day. I have absolutely no wheel hop now. My mods are FRPP 4.10s, Steeda U/D pulleys, CMDPs, Pypes O/R X, Flows and C&L CAI and SCT Tune. Shipping is always fast and AM customer service is second to none.

    no more wheel hop

    Installed these with a floor jack, jack stands and no air tools and nobody helping me. Took about an hour and a half. Went to a local tire shop and had them torque down the bolts because there wasn't enough room under the jack stands to get that much leverage. These things work great.
