UMI Performance 2310CM-R Upper Control Arms A-Arm Set with Ball Joints

UMI Performance's fabricated tubular upper A-arms provide a rock-solid foundation for 4th generation Camaro and Firebird front suspension systems. Built in Philipsburg, PA, these control arms are engineered to deliver increased caster, smooth non-binding travel, and precise steering response for drag racing, autocross, road racing, or street performance applications.

Construction and Materials:

• Precision-bent 1-¼" USA mild steel DOM tubing for exceptional strength
• TIG-welded 4130 chromoly threaded tube adapters ensure thread durability
• CNC-notched and jig-welded construction for consistent quality
• ⅜" thick CNC laser-cut ball joint pads for maximum strength
• Available in durable red or black powder coat finish

Performance Features:

• Premium upper ball joints installed and ready to mount
• Relocated ball joint pad provides 1-2 degrees of additional caster
• Adjustable design allows fine-tuning of both caster and camber settings
• Teflon-lined high load capacity race rod ends reduce suspension friction
• Non-binding rod end design ensures smooth suspension movement
• Industry-leading travel and clearance—ideal for lowered vehicles

Installation:

• Uses balance of OEM hardware or optional UMI hardware kit (P/N 2302 sold separately)
• Hardware kit includes Grade 10.9 bolts, washers, and Ny-lock nuts

The chromoly upgrade version (P/N 2310CM) utilizes 1-¼" 4130 CrMo tubing, maintaining full strength while reducing weight by an additional 1.5 lbs per set. These A-arms represent the perfect combination of strength, adjustability, and performance for serious suspension tuning.
