The MOD Upper Control Arm was designed to replace the stock piece in your early Mustang while improving strength and serviceability, resulting in a more predictable and confidence-inspiring ride.
We’ve redesigned the upper control arm to greatly improve ride quality while including several features that benefit your alignment and suspension performance. First, we replaced the shaft with our MOD shaft assembly. This user-serviceable part is easy to use and can be quickly disassembled and reassembled without expensive presses or tools. The bearing we use allow for full range of motion up and down, adding to the comfort and performance of your car. We also set the shaft up to use swappable alignment keys, letting you easily dial in exactly where you want the shaft to sit without having to drill additional holes (as you would for the Shelby drop).
Second, we designed the arm to be A-symmetrical, engineering more caster into the arm while still maintaining the original suspension layout. This helps the car track straight down the highway with confidence at any speed.
Third, we improved the shock and spring location mount points. By relocating the spring saddle mounts towards the ball joint the spring and shock become more responsive without over springing and dampening your car.
Finally, we updated the ball joint to a screw in K772 style, giving you a bunch of options for aftermarket ball joint replacements, including ones easily found at your local parts store. A quality ball joint enhances steering feel and stability, improving performance and handling.
Enhancing the mechanical attributes of the stock suspension not only increases your confidence, but greatly improves the performance of your car. So whether you are looking for a true touring car or a corner carving beast, the MOD Upper Control arm will get you one step closer.
