UPR Chrome Moly K-Member & 1" Short Adjustable A-Arm Kit (2005-79K-104) - 1979-2004 Mustang
Maximize clearance, reduce weight, and fine-tune your stance with the UPR Chrome Moly K-Member and 1-inch Short Adjustable A-Arm Kit. Designed for serious street and race builds, this setup delivers the strength and performance needed for everything from drag racing to aggressive street driving. The shortened A-arms are ideal for lowered vehicles, pulling the wheels inward for improved fitment and clearance when running wider tires or dialing in your stance.
Constructed from premium 4130 seamless chrome moly tubing, this system offers exceptional strength while reducing front-end weight by up to 70 pounds compared to factory components. The included adjustable A-arms provide up to 1/2 inch of fine adjustment, allowing you to dial in alignment and handling. Paired with UPR’s front coilover kit featuring a tool-free ride height adjuster with locking set screw, this package delivers unmatched control, durability, and ease of setup for high-performance applications.
