Description
Faster Launches. Improve your 60 foot times and get better, straighter, faster launches with a pair of J&M rear lower control arms. By replacing your factory control arms with a set of J&M's arms, you'll eliminate suspension flex that causes "wheel hop" when you're accelerating or braking.

Better Handling. Your stock control arm bushings can bind when you're cornering, causing sudden changes in handling. J&M's unique 3-part bushings rotate freely to keep your Mustang's suspension planted even around hairpin turns.

Industry Leading Design. Unlike other designs that use single piece polyurethane bushings, J&M's patented 3 part bearings offer the best for both straight-line performance and handling. 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.

Made to Last. The J&M rear lower control arms are made from lightweight round tubing for maximum strength and finished with a black powdercoat for durability and good looks.

Application. These J&M rear lower control arms are sold as a pair and are made to fit your 1999-2004 Mustang perfectly.

Do you need to press these bushings? do you need to press these bushings using a hydraulic press?

  • No, only stock bushings with the metal shells need a press.

    lower arms

    thankfully, the instructions on the website had all the answers i needed when installing the upper and lower control arms on my car. i have to say they have made a huge improvement in the way my car takes turns. its almost like buying a piece of mind, knowing that my car is a bit more stable in the rear now. i would highly recommend them to anyone that is feeling the need for more stability in either their track or daily driving.

    Amazing Control Arms

    Holy S#!T, those were my words after a launch with these control arms installed on my 97 Vortech SC Cobra, running small 245s wide stock tires, these control arms made them hook. I just felt my car sit down and move forward fast without burning out. Ride Quality also improved great. These control arms are awesome.

    Great buy

    Definetly has made an improvement to my launching at the track. When accelerating out of corners I am more confident with regards to the rear end holding the road. The ride quality improved too.

    really strong luanches

    I bought these thinking they would tighten up my rear end in the corners cause I love to take turns and do a lot of road course racing. well these arms are great. they make the launches harder then I've ever felt before. the only thing is when you go to take a sharp turn with some speed behind it the arms flex and makes the rear end feel like it's not even part of the car. It feels like the rear end is kinda like a trailer. these arms I would say are mostly for drag racing straights. I think its mostly due to the ball joint style bushings. I still recommend these arms. Great improvement over stock. just don't take the turns to hard.

    BIG IMPROVEMENT

    I'm not much of a track guy but the stock bushings were gone in my stock control arms. I installed these lowers and went from a 14.2 with Exhaust and CAI to a 13.8 on a 275-35-18 street tire on Saleen rims.

    Speechless Improvements! Should come factory installed!

    Very big improvement over the stock lower control arms! The bushings in the stock arms are so soft allowing the rear end to literally move side to side. I used to be all over the place while launching (squirrely), not any more! Improved my launches big time! Even the gf noticed the car was much straighter during launches and accelerating. I was blown away by the improvement from these J&M LCA's and wish I didn't wait as long as I did to purchase these. Buy these and don't look back!

    Wow!!!

    I had my LCAs installed by a local ma and pa shop, cost $130. I noticed the difference immediately. I took the onramp onto the 401 (freeway) kicked it down and felt tight. 0-60 felt like a kick in the butt, just strong forward movement. One of the best purchases so far!!!!!!!!!!!

    Big improvement over stock!

    The only problem I had was that the bolts in the rear axle were rusted in. Lots of WD-40 and a big hammer and the rest of the install went as planned. I haven't tried it out at the track yet but the rear of the car feels more stable.
