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.

Stop the Hop

These LCA's are awesome. Stopped the hop in my 07 Supercharged GT and helped stiffen up the launches. I would highly suggest these LCA's to anyone!

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

    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.

    regret purchase, sqeak buzz kill

    Had the item installed, less wheel hop but squeaks terribly, you hear everything, making sudden stops and going over bumps... i have to turn music all the way up not to hear it, a new car shouldnt be making all that noise, embarrassing, people ask what noise is... i regret buying, wished father never tossed original parts accidentally so im stuck with these...im very disappointed...

    • Response from AmericanMuscle

      These control arms should not be squeaking; in fact, just the opposite. They should have gotten rid of any squeaking you may have had prior to installing. It's possible one of the bushings is bad. If you can give our customer service a call at your earliest convenience, we can help get this issue resolved quickly.

    J & M Lower Control Arms

    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.

    J & M Lower Control Arms

    Great product. Installed with help from wife in couple hours. reused factory hardware but would have replaced factory lock-nut as some patience will maintain integrity of threads on bolt. Best of all wheel hop greatly reduced.
