Features & Details

  • Improves Traction
  • Better, Faster Launches
  • Lifetime Bushing Warranty
  • Sold as a Set of Two
  • Fits All 79-04 Mustangs
Better Launches. Replace your upper control arms with a set of J&M Mustang Rear Upper Control Arms for better, faster launches and to eliminate that uncomfortable feeling of "wheel hop" under heavy acceleration or braking.

Better Than the Competition. Unlike other products, the J&M Rear Upper Control Arms use a patented design to keep your Mustang's rear end planted when you mash the gas on the starting line while also improving your handling. Their unique 3-piece "Poly Ball" bushing allows your control arm to move freely when you're carving the corners but keeps it stiff when you're romping on it on the strip or slamming on the brakes. It's truly the best of both worlds.

Made to Last. Everything about these control arms is designed to last - J&M is so confident in their bushing design, they back them with a lifetime warranty should they need to be replaced. The control arms are made from round tubing for strength and finished with a gloss black powdercoat for durability and good looks.

Application. These J&M Rear Upper Control Arms are specifically designed for use on the 1979 to 2004 Mustangs with a solid rear axle, not intended for use on 1999-2004 SVT Cobra's with IRS.

    Love the 3 piece bushing design!

    You can't go wrong with J&M Products. I have since turned my car back to a street car and ordered these upper Control Arms because of my previous experience with the J&M weight jackers. I love these uppers because of the durable yet soft 3 piece bushing design and the construction of the control arms themselves. They are quiet and plant the rear tires. I have not noticed any wheel hop. If you are thinking of putting these control arms on your car I highly recommend them. They are built to last. The black powder coat finish and the welds are very nice. The 3 piece bushing design is not just hype! I have owned many different upper and lower control arms and none of them compare to this design.

    JM Rear Upper Control Arms 79-04

    I did a total front & rear suspension rebuild. I purchased JM upper and lower rear control arms. The uppers bolted in nicely, right in, no problem. They weren't the cheapest out there but worth the money. Along with the new rubber bushings on the rear end & hardware the car handles really nice. I would purchase them again for sure.

    I'm impressed with the difference in handling these made. Big improvement over the stock UCA, no binding, eliminated the noise I was having with suspension movement. Received them quick from AM and at a great price!

    J&M Rear Upper Control Arms

    Much much stiffer than stock. Before when taking a corner in stock I could feel the flex in the rear end. Now with these upper control arms it is a huge difference. I also upgraded to adjustable shocks and UPR 4bolt caster camber plates... and the car is completely different it handles so well.

    J M control arms.

    My Mustang had cheep lower and upper control arms, I replaced the lowers last spring with JandM and now the uppers with JandM. Took care of clunking from the old broken bushings, the 3 pice design works great well worth the the change.

    Great product!

    It's been about a week since I installed these upper arms, they are well constructed, and pretty beefy. Install was a snap, and took me half the time of the lowers, There is more noise and harshness to your ride quality I thought I should mention for people considering these. But no regrets, the car rides and corners a lot better coupled with the JandM lowers you won't be disappointed.

    Amazing

    I bought these because I wanted to improve my take off speed and it's excellent. Traction was improved and very noticeable. They are easy to install if you know what your doing and if there's no rust on your car

    Simple yet amazing!

    Had these uppers sitting in a box for about a month before I had the chance to install them. My 02 GT has 190k miles on the original suspension and the bushings on the stock uppers were shot. Was recommended that I just replace the whole upper rather than just the bushings. The install would have been rather "easy" but the stock bushings on the axle side had steel sleeves with teeth. I was not expecting to see those which extended the install time to about 1.5-2 hours of prying and hammering to get that side on. Had help from a couple people and it was still a pain even on a lift. However I do not regret installing these as I felt an immediate change. My car doesn't lean as much in the corners or dip so much during braking. No more creaking or rattling, at least from my upper control arms.

    Very beefy construction!

    Had a hard time getting supplied bushings to fit into chassis brackets. Also getting axle bushings would have been nice as my original bushings had cracks in them.
