You don't have to look any farther for tubular control arms for your hot rod. Full .120 wall, 1" diameter tubing, fixture welded and features screw-in ball joints and no-squeak bushings. These lower arms are designed to be used with strut rods and coil-over shocks. Will work with nearly any stock or aftermarket crossmember. Welding may be required on some applications.

Replaces 1974-80 Pinto, Bobcat and 1974-78 Mustang II control arms.

  • Full .120" wall
  • 1" diameter tubing
  • 13-1/2" center to center and 6" at widest point
  • 15-3/8" overall in length
  • Weigh about 6-1/2 pounds (each arm)
  • Pivot Point width: 3.380"
  • Fixture welded
  • Screw-in ball joints
  • No-squeak bushings
  • Works with Mustang II crossmembers that come without lower A-Arm tabs and require strut rods
  • Designed to be used with coil-over shocks

Note: These lower control arms will require use of a strut rod and strut rod brackets. We recommend our tubular strut rods (91034322).

Note: Consider our Mustang II Lower Arm bolt kit (91034311-2) for proper installation.

Overall Assessment

Customers highly recommend this product due to its quality and ease of installation. Notably touted for its excellent fit, our product has proven vital when dealing with coil overs and suspension alterations. Reviews highlight the solid welding job and robust make, suggesting it as a reliable replacement for stock parts. Some users have expressed the need for extra washers for an optimal fit, but still appreciate the product's practicality and durability. Others additionally valued its aesthetic appeal. Despite some desiring an unpainted option for custom coating, the vast majority praised the product's performance, price, and usability, even considering it for future projects.

I just want to say how happy I am with Speedway Motors. They make it easy to like them. From ordering the parts and really, when you have to return something. Simple, easy, and no bs. As for the control arms, their mounting holes are a little too big for the shock to mount to. You will have to take a file to it to make the shocks lower mounting fit. I would like to see them power-coated or painted

Would Recommend

Great addition to my project.

The Team at Speedway Motors is unbelievable on their support for the product both during the purchase process, but more importantly the technical support after the sale. I had an issue with the QA1 Coilovers (sleeve fitment - bolt size was different). The Tech Team reviewed the issue with me, and then supplied the right fix to solve the issue without a second of quibbling. It was a great experience working with their knowledgeable staff. Something that's far too rare these days.

Not a direct fit to the Speedway coil overs, had to use washers to take up slack in the cross bar of the shock, (4 thick washers on each)

Product appears to be well made. Quality welds. Have not yet installed the control arms as I'm waiting on Viking coilover shocks which are taking way too long to get. Speedways order was fast and efficient.
