      • Improves Traction & Launches
      • Better 60 Ft Times

      • Heavy Gauge Square Steel Tubing
      • Sold as a Set of Two

      Faster Launches. Plant your Pony's rubber firmly to the road with a pair of Maximum Motorsports' rear lower control arms. Unlike other aftermarket control arms, Maximum Motorsport's arms feature a unique design to reduce axle windup. The result? Faster, straighter launches and lower 60 foot times.

      Better Handling. The stock rubber control arm bushings can bind when you're cornering, causing your Mustang to suddenly and unpredictably lose traction. Maximum Motorsports uses a 3-part bushing at the chassis end of the arm that stays rigid under acceleration but allows for movement when cornering for maximum handling. On the axle end, they use a Teflon-lined spherical bearing for freedom of motion and to prevent chassis damage.

      Made to Last. The Maximum Motorsports lower control arms feature a durable black powdercoat for a great-looking, long-lasting finish.

      Application. These Maximum Motorsports lower control arms are designed to fit 1999 to 2004 Mustangs and are sold as a pair.

        Maximum Motorsports Rear Lower Contro Arms

        I installed these Maximun Motorsports Lower Control Arms today and the install didn’t quite go the way I thought it would, or should I say as easy as I thought it would. It took a lot longer than expected mainly because the directions seemed to be confusing about which way or side the control arms was supposed to face. More pictures and more detailed instructions would have made my install easier. It too me about 3 hours to install them. I wanted something different than the stock stamped steel ones when I pit on the coil overs that I bought from AM. Once the rear was buttoned up they look good.

        What you expect

        High Quality Control arms highly recommend makes car control immense over stock. Just get a pry bar and breaker bar, I did it with Jack stands and had to jack up pretty high but is still sorta easy job. Also used hydraulic press to get bushings in. Don't know if others needed to do this but bushings weren't fitting in perfect.

        MM Rear Lower Control Arms

        I have to say that purchasing this upgrade was a win win all the way around. Superior performance and quality for half the price of flimsy OEM replacement parts. Yes, 2003 Mach1 OEM rear lower control arms were $249 EACH from my local auto parts store. American Muscle offered the MM version (MMRLCA-5) at $259 for the set. I used a $10 coupon code and the free shipping which equaled HALF THE PRICE. Installation was pretty simple. My only issue was that the included instructions were very generic. The photocopied diagrams showed very little detail. If you are running any kind of aftermarket exhaust, you will need to loosen and lower the mufflers about 3 inches so that you can remove the front mounting bolts. Besides that, everything went very smoothly. Its been a week and the noticeable binding "popping" sound while making a very sharp turn has completely disappeared. The noticeable suspension stiffness has softened up. The wheel spin (after initial installation)appeared to be worse but, after driven around a bit and broken in ,it has improved dramatically. Overall opinion is that this purchase was an amazing Win-Win. I would definitely recommend these to other folks.

        Best LCA on the market

        These worked so well on my prior Mustang GT that I bought them again. These are a great option for a non adjustable lower control arm. My car feels more planted. The rear axle doesn't feel loose and rubbery when you hit bumps and traction on take off is greatly improved. It's harder to break the tires loose. Maximum Motorsports is one of the best brands for mustang suspension.

        MM lower arms make a big difference at launch.

        looking for some upgrades at your suspension, I would start with control arms they make a big difference if you like to go hard on launches.

        Instant noticeable handling difference

        install is simple and quality is great. the difference is clear, when going from stock. the car no longer dips down/ twists when stepping on the gas. The car also goes straight now also when spiritedly starting from a stop.

        Finally I have a car that just hooks up now. The factory lower arms where just shoot. Also added a set of ford c spring to the mix. Car know transfers weight and doesn't bottom out any. Yes I would recommend this product.

        Highest quality control arms.

        I installed these control arms and it is literally hard to break the rear end loose on my mustang now. The quality of the welds on these control arms id phenomenal. The install took about an hour and let me tell you that these lower control arms make a huge difference in the way the car handles. They keep the tires planted on the pavement where they belong. I highly recommend these control arms.
