Hey. everybody, I'm Justin with AmericanMuscle.com, and in this video, I'm gonna be talking about a few upper and lower control arm options from BBK, available for your '79 to 2010 Mustang. If there's ever been one company that has truly flown the Mustang flag since day one, it's BBK. They've been showing their support for the Mustang and it's owners since the mid-80s, and show no signs of letting up anytime soon. As many of you guys probably already know, BBK makes a wide variety of parts for many different applications, including exhaust systems and cold air intakes, headers, and even suspension components like I'm talking about here today. Now the parts I have with me in this video consist of an upper and lower rear control arm kit, available for both your three and four link Mustang. So when ordering, just make sure you grab the right set for your generation. So the job of the rear upper and lower control arms is to brace and link the rear end of your Mustang to the chassis itself, and ultimately control the movement, hence the name control arm. Now the problem is the factory stuff contains soft rubber factory bushings that do a great job soaking up the excess noise vibration and harshness, but can often times leave a lot on the table when it comes to performance. Now this can cause problems such as bad wheel hop, poor traction, and inconsistent launches, just to name a few. The upper and lower arms from BBK are gonna improve on those areas I just talked about, thanks in part to the high-quality aircraft grade steel, precision welding, and most importantly, the high-performance polyurethane bushings. They're gonna help reduce any excess movement in the rear end, help you put that power down, and improve your handling in the process. Finally here, all the bars have been powder coated in the signature gray from BBK and do include greaseable fittings here to help prolong the lives of the bushings themselves. Since the kit from BBK does include both the upper and lower rear control arms you are gonna be spending a little bit more time in the garage, but overall the install shouldn't be that bad, maybe two out of three wrenches on the difficulty meter. Now we do call this one a full-day install on the site, but I wouldn't be surprised if some of you guys can bang this one out in six hours or less, just to get everything knocked out. So always guys, if you have any questions whatsoever, feel free to reach out to our team of Mustang experts here at AM anytime. They're always standing by ready to give you a hand. So if you guys are looking to put the power down, get off the line a little better, and improve your handling in your 1979 to 2010 Mustang, be sure to check out one of these kits from BBK right here at AmericanMuscle.com

I've had these on my 1999 GT for approximately 20,000 miles now. Did my entire suspension setup in one go. This pairs well with the Eibach kit that is also available on this site. If you primarily use your car on the street, these will be just fine for you. Makes the rear end feel much more planted with noticeably less squat under hard acceleration.Helpful (1)

Great for mild build
Put them on my 99 cobra with 8.8 SRA swap and all I can say is WOW. I had the stock LCA and UCA with really worn out bushing, it was bad enough to the point where the axel was sticking out the drivers side more than the passenger. Not only did this fix the problem but also the steering is much tighter around tight turns with both wheels staying planted, the only other suspension mod is eibach pro springs and it handles just as well as it did with a stock IRS, but without all the wheel hop !Helpful (0)

Can't get parts
that are also needed to install them I've been waiting several weeks now? Not happy yet but the parts that came look great sitting on the floor in my shop, doesn't do me any good if I can't get bushings for them...Helpful (5)

The parts are solid and feel much better than stock, however they don't come with the bushings. AM didn't have the bushings for this either so I had to get those from another company.Helpful (7)

High quality, strong materials. Looks great installed, goes well with energy suspension red poly bushing sets. Perfect fit, easy installation, future proof design with grease fittings in all bushings.Helpful (5)
Does the kit come with new bushings for the upper control arm where it bolts to the rear end?
This BBK control arm kit does come with all the bushings for the control arms needed for a complete installation.
I was considering getting the Bilstein quad shocks for my 2003 Mach 1 but wanted to know if this BBK control arm kit would eliminate the need for the quad shocks.
The BBK Rear Upper & Lower Control Arm Kit will certainly help with wheel hop and handling just as the quad shock would. You can certainly remove your quad shock if you would like after installing this kit and you will not notice any decrease in performance.
will these work on my 04 gt with the sr lowering springs I have the sr springs and was wondering if they will work without having adjustable uppers for the pinion angle ??
The BBK Rear Upper & Lower Control Arm Kit (99-04 GT, V6, Mach 1) will work with the SR Springs without having to adjust the pinion angle as the SR Springs are not an aggressive drop.
Will these work in conjunction with the Ford Performance Lowering B Springs?
You would be able to use these control arms with the Ford Performance Lowering Springs.
Do I have to add grease or are they ready to install out of the box
You will want to add grease upon install.
These will include Polyurethane Bushings.
Torque spec for both the upper and lower control arms is 70 ft. lb.
The BBK Rear Upper & Lower Control Arm Kit will include all bushings that install into the control arms.
The BBK Rear Upper & Lower Control Arm Kit will include all bushings that install into the control arms. The upper bushings in the axle are reused as these press into the axle and not the control arm. You should not have any issues using these control arms with a lowered Mustang.
The BBK Rear Upper and Lower Control Arm Kit can be used, however an adjustable set of control arms would be preferred for cars dropped 2" or more to allow adjustment of pinion angle.
The BBK Rear Upper & Lower Control Arm Kit would be a great install if you have a lowered car that is heavily used for the track. It all depends on what you use the car for when deciding what parts to upgrade.
The BBK Rear Upper & Lower Control Arm Kit will work with Eibach Pro System Plus.
The BBK Rear Upper & Lower Control Arm Kit would not be the best option for your drop height. We would recommend looking at adjustable control arms due to the drop you have.
These control arms are not rated for a specific amount of horsepower, they are designed to assist in added traction while cornering and in launches. If there is a scenario where the car is making so much horsepower that a factory rear end would be moving to much then a completely redesigned rear end would be required.
The BBK Rear Upper & Lower Control Arm Kit will have no effect on ride height. What they will do is provide better traction at launch, and better handling through the use of much stiffer designed boxed steel body vs the factory stamped steel, and stiffer polyurethane bushings over the factory rubber bushings.
