Check out our 5/8" narrower than stock width upper control arms (91034326) for applications that require a shorter track width. These allow you to tuck the wheels up under the fenders without having to buy expensive special offset wheels.
Why go with tubular control arms? The most obvious reason is the looks. Tubular control arms and strut rods give your hot rod a much cleaner and hi-tech appearance than the stock type do. Another bonus is that the tubular control arms are available in 5/8 " narrower than stock, which helps tuck the wheels up under the fenders without having to buy expensive special offset wheel. When using 5/8 " narrower control arms, 1 " must be removed from each inner tie rod end.Why go with tubular control arms? The most obvious reason is the looks.

Good not great
A must for dropped spindles, it is bare metal, need powder coat or undercoat them. I think instructions are backwards where as shock bolt hits strut rod. Love the screw in ball joints. Needs never seize they go right in. I would buy them again. I think a little overpriced.

I autocross a 74 Pinto which has the same suspension as a Mustang II. I'm looking at these to gain some more negative camber as the smaller bushings would enable me to push them back further. Are these strong enough to handle hard cornering and braking that you would subject them to running an autocross and even road course on track days?

Do you sell replacement bushings for this control arm ? I need replacement bushings for this control arm. Do you sell them or can you tell me a part number for a replacement bushing and where it can be bought ?

Your answer showing "10 1/4" at widest point" leaves me wanting to be sure that the widest point is from the cross shaft to the ball joint, not from I want to put standard tubular control arms on a Mustang II front end on a 50 GMC. The tubular control arms now on it are so narrow the ball joint touches the spring. So I think they must be the "narrow" ones. I see reference to "5/8" narrower", and while 5/8" wider would certainly help this truck, the dimension of 10 1/4 at widest point would be even better, if the widest point you mean is the widest point I'm thinking.
