Features, Description, Reviews, Q&A, Specs & Installation
Improves Handling. J&M's street tuned rear lower control arms will help keep your Mustang's rear end planted even under high RPM launches. Their exclusive design eliminates undesirable handling characteristics of the S197 suspension without compromising on cornering.
Better Than Stock. Due to issues with suspension design, your stock bushings are very soft, which can cause wheel hop during hard braking or acceleration. The J&M Rear Lower Control Arms offers a patented bushing design that eliminates wheel hop and improves straight line grip.
Better Than the Competition. Unlike other products, the J&M Rear Lower Control Arms have a unique design which combines the straight-line performance benefits of a hard bushing with the handling benefits of a soft bushing.
Premium Quality. Made from round tubing for strength and finished with a black powdercoat for durability and good looks, the J&M Rear Lower Control arms are perfect for any street or strip driven 'Stang. And these arms are made to the same tolerances as their race performance arms to assure a perfect fit and long life. And J&M backs their bushings with a lifetime warranty for peace of mind.

Believe it or not, the car rides better
I bought these because of the old control arm bushings were dried out and dying a slow death. Once installed the car actually rode better. We believe it is because of the free moving ability of the rear end rather that the stock bushings that twist back and forth in the stock control arms. These can be installed fairly quickly if you have a car hoist. If not it can be done in the driveway but will take more time and can be a hassle.Helpful (0)

Rear Control arms.
Definitely helped eliminate wheel hop. They are a bit creaky though, and yes, I used all of the included grease. I think there should have been one more grease packet included. I'll pull them out and re-grease if it co tinues to bother me Installation was pretty easy, but torquing to 130 lbs, while on your back with the car on jack stands, was a challenge.Helpful (0)

'11 V6. Great deal considering quality and price. Trouble installing for me-actually split 18mm 12 point with breaking bar to get front bolts off. Meh. Definitely suggest saving half hour by CAREFULLY using cutting wheel to free EM breakline (unless you plan on reusing the original?).Helpful (0)

Solid feel with a little extra noise
These eliminated the wheel hop from the stock arms and really makes the rear end feel a lot more planted. There is a bit more noise unfortunately, and just a slightly rougher ride. I would say the noise is more noticeable than the firmness.Helpful (9)

Easy to install. Simple design and works great. Had a squeak on rear right side. Could not figure out what it was for the longest time. Finally narrowed it down to the lower control arm. Squeak is gone!Helpful (8)

Mine have rubber bushings how to do i go about getting ploy bushing for the set I already have?
I recommend shopping around online for polyurethane bushings for your stock control arms. The J&M Rear Lower Control Arms kit comes with 4 polyurethane bushings, 4 cupped polyurethane bushings, and 2 polyurethane inner balls. If you are looking to upgrade both your Control Arms and bushings, this is the kit for you.
Are these recommended for a lowered ride? Going to be lowing my ride soon 1.4" nearly and adding shocks/struts. My car isn't completely a daily driver nor does it ever see the track. Should I install a pair of these LCA and the UCA as well with the springs and dampers?
I absolutely recommend these control arms, and especially if your car is lowered. I have my 05 V6 Convertible lowered 2 inches, and before I put these on, my rear end was noticeable loose. After I installed them, the rear end had far more directional stability and it would keep the car better planted to the pavement while cornering. On and off ramps can now be taken at higher speeds, subject to tire condition of coarse. If you are lowering your car, I would also recommend getting Rear Lower Control Arm Relocation Brackets. In order for the Lower Control Arm to do what it is designed for, it needs to have a slight downward angle going toward the rear. This will accomplish that. They're available here as well and you'll down in the rear end anyway, so might as well do it all at once. And. yes to everything else you asked.
Hardware included? Will everything I need for the install included? If not what do I need to get along with these lower control arms?
Nothing else is required to install these. You the arms are complete and you will just simply reuse the stock bolts to install.
Will these help with 4.10 gears? I have 4.10 gears along with a lot of other mods and my car has a hard time getting traction off the line, I usually float and go to the left and don't get traction till the end of 2nd or beginning of 3rd. Would these help me get better traction off the line and stay in a straight line?
I have these and I think they are great! They will help your launch because of the harder bushings over stock there is no play with these and will also almost completely eliminate wheel hop, enjoy
Do I need another allignment after installing these? My car has ford racing springs on it (1 inch drop) and has already got an alignment done for that.
Not at all I have the h&r super sport springs and these rear control arms and the fit is great and these control arms are amazing they are so inexpensive and they completely get rid of wheel hop!
I daily drive my car and have these lower control arms on my car and I have not had a problem.
