BMR rear upper control arms, non-adjustable, with polyurethane bushings for all 1979-2004 Mustangs.

Stock control arms are marginal at best. Bushing deflection combined with control arm flex creates erratic handling and inconsistent rear end stability when subjected to the added loads of performance driving. BMR control arms are built using 1-5/8" x .120" DOM tubing and utilize 1/4" thick mounting plates for a bulletproof combination.
Upper control arms are available in either fixed or adjustable versions. Adjustable uppers allow "on-car" adjustability by simply loosening the jamnuts and turning the adjuster. This allows you to adjust your pinion angle without unbolting the control arm, a convenience not offered by most other companies.

Features a durable black hammertone powercoated finish.

The upper and lower rear control arms on your '79 through 2004 Mustang work together to put power to the ground by stopping the rear from moving around, and also stopping it from rotating. In my opinion, when replacing control arms, you should replace all four at the same time. If you replace just the lowers, it can put a lot more strain on the worn out uppers. We've already installed BMR's lower control arms on our 2001 Bullet, so today we're going to finish off the install by installing the BMR uppers.

We're going with the BMR solid tubular uppers in the hammer-tone finish to match the lowers. Just like the lowers, these are available in both the hammer-tone or the red finish, come with a high quality polyurethane greaseable bushings, and everything needed for installation. For this installation, a lift and a pull jack, or a jack and jack stands, 1/2 inch ratchet, 3/8 ratchet, an assortment of shallow and deep 18mm sockets, and an 18mm wrench.

We're going to take the upper control arms off one side at a time. First thing you want to do is support the rear. It's not going to go anywhere, but when you put the control arm on and try to line the bolts up, it's easier to have it supported to line it up. We move on to the rear bolt.

Here, you can see the obvious quality differences between our BMR lowers, and our factory. See how it's stamped, it's all real thin metal. The flange is much heavier duty. The overall design is a huge improvement over factory. Put a little of the supplied grease on the new control arm, and put it up into place. This is where you may need to adjust a little bit, you've got to get it to line up. Install the nuts, and tighten down. Repeat the process on the other side, and your installation is finished.

If you're looking to keep the solid axle rear in your '79 through '04 Mustang from moving around and rotating in acceleration, you definitely want to replace the upper control arms if they're work out. Installation's not too bad. Some of the bolts are a little tough to get to, but overall, you can do it in around two hours. You'll be back on the road in no time.
