The Factory stamped steel rear lower control arms are not strong enough to hold up to hard launches. Which means the harder the car accelerates on launch, the greater the force on the lower control arm bushings. Higher forces tend to lead to a shorter lifespan of the factory rear lower control arms. These Maximum Motorsport rear adjustable lower control arms are tested by Maximum Motorsports engineering team. Offering the best suspension performance the company can offer.

Video Transcript

Bill: We have Jack from Maximum Motorsports in our studio today, he brought this killer display with him. Jack handles high level tech support, as well as works with the engineers. He's going to tell us about some of the products they make for your Mustang. Jack, your lower control arms are probably one of our top sellers. There's always been some confusion on what the different models are, and what the differences are. Can you explain them to us?

Jack: No problem, Bill. For the '79 to '04 cars, we have our heavy duty lower control arm with an adjustable spring perch on it. This model has a spherical bearing in the rear half. It has a 3-piece polyurethane in the front half to allow easy articulation and smooth motion. The adjustable spring perch gives the owner the ability to adjust the right height with a 1/2" ratchet. They just stick it in the bottom of the control arm, and they can raise and lower it easily. This is especially useful if you have a drag race car for instance, and you take it to the strip, and you put large slicks on it, and you need more tire clearance. Or if you're a road racer, an auto crosser, and you drive the car to the track, when you load all your floor jack, jack stands, tires and everything in the car, when you get there you want to have the car low, but during the ride, you want to have enough ride height so the car's not bottoming out. You can raise it up for that, and lower it at the track.

On this side of the display we have our extreme duty lower control arm. This unit has a spherical bearing in the rear like the heavy duty model, but it also has a spherical bearing at the front. The bearing isn't visible on the control arm because there's polyurethane thrust washers used in the front to keep the control arm from rolling when the spring load is applied. This particular model does not have an adjustable spring perch, it has a fixed spring perch. It's a little lighter than the other model, it's a little less expensive, and it can take higher power levels. We offer combinations of extreme duty with adjustable perch or fixed perch, and heavy duty with adjustable perch or fixed perch.

Bill: How's the NVH going to be on the extreme duty by getting rid of that normal front bushing and going into that sleeve?

Jack: That really depends quite a bit on the condition of the car. For example, if you have a full interior car and it's a later Sn95 model, the NVH difference won't be that large because the sound deadening, and the rear seats and so forth will absorb a lot of that energy.

Bill: On a race car you'd probably hear it more, but you can hear everything else anyway.

Jack: Exactly. On a race car it's going to be much louder, but it's irrelevant.

Bill: Jack, we appreciate you coming out today. Thank you for telling us about your products. If you're looking for a high performance suspension for your late model Mustang, make sure you check out our selection of products from Maximum Motorsports.
