Your 05-09 Mustang's stock upper control arm has a design that can result in sudden, unpredictable changes in handling, especially under hard cornering or acceleration. By replacing your stock upper control arm with a J&M adjustable upper control arm, you'll enjoy better cornering, quicker launches, and eliminate the dreaded "wheel hop".
The J&M Adjustable Upper Control Arm can be adjusted on-car for on-the-fly changes, and they are double adjustable so you can get settings just right.
J&M uses a unique 3 piece poly-ball bushing combination to keep their bushing moving freely under cornering but maintain stiffness under acceleration. The result? Your Mustang’s rear end will stay planted with no wheel hop on hard launches! Or if it’s twisty roads you’re after, this’ll also stop the rear from jumping or skipping during turns when you want to push it to the limit!

Everytime I have delt with LateModel, it seems to get better and better. I have had all positive experiences which is much more than i can say about Summit, or American Muscle. I like the mom and pop shop feel i get when i deal with LateModel. We had a family buisness turning wrenches and a huge part of our success was customer service. Specifically treating every single female as how we would want our sister of mother treated when going to a buisness. We were always more than fair, accommodating and made sure to make all of our customers leave with a smile. And it worked. 30 years later my brother is still in buisness. Yesterday, I got that same type of treatment by Ian. Thank you Ian, you really went above and beyond like this was your personal buisness. Late Model, you just def locked in another lifelong customer thanks to Ian. Semper Fi
