    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.

            Rear End Under Control

            I went from traditional styled poly bushings to these “poly-sphere” type and I’m floored by the difference. These feel better in the turns and are worlds quieter. Granted, my traditional styled bushings were very worn out, but still. I have the uppers and lowers installed and feels planted in all aspects.

            Great for the price

            Very well built control arms. Can't believe they're not more expensive! I do wish they had a grease fitting, but with the 3 piece design of the bushing, maybe it's not possible. Installation went as well as any other UCA and they look stout in place. Definitely more than strong enough for my GT with bolt ons. I'm plessed!

            Big difference

            Pretty straight forward to install. Just remember to put bolt in front bush first and lower axle down a good bit so you can get rear bolt it. Great product

            Replacement for destroyed poly bushings

            These arms went in great and provided the correct axle location I needed. The bushings were easy to install if you follow how they do it in the video. It replaced another popular "brand" that had poly bushings that were basically eaten away. I don't recommend poly bushings in the upper arms if you're still running the stock 4 link setup. The unique bushing set up will allow proper articulation of the rear axle and fixed the issue I was having.

            Better bushings

            I bought the SR performance upper and lower control arms, they were great for about 6 months and the bushings just fell apart. I’ve now had these on for about two months and so far so good.

            My rear end would make a clunking noise and it sounded bad. Had these installed and no more noise. Turned out my originals had a worn bushing. Definitley worth the money!

            All around well built product. I had the SR performance on and the bushings just fell apart. Put these in and am loving them so far. The bushings are a pain in the butt to put together but they have a lifetime warranty on them so why not.

            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.
