UMI Performance FBS002-B Stage 2 K-Member Kit with Tubular A-Arms for GM F-Body

The UMI Performance FBS002-B Stage 2 K-Member Kit delivers the perfect balance of weight reduction, strength, and performance for street-driven F-Body vehicles that see drag strip duty. This complete front suspension upgrade combines a heavy-duty dual-tube k-member with tubular upper and lower a-arms to provide a solid foundation for aggressive driving while maintaining street comfort.

Heavy-Duty Dual-Tube K-Member Construction:

UMI's dual-tube k-member design is recognized as the strongest in its class, capable of withstanding wheel stand landings and street abuse while saving 33 pounds of front-end weight. Precision-engineered from USA DOM tubing, the k-member is CNC notched and jig-welded for consistent fitment and maximum strength. The design provides superior oil pan protection and works seamlessly with factory motor mounts, polyurethane motor mounts, or UMI's solid billet aluminum motor mounts (P/N 2323).

Tubular A-Arms with Premium Components:

• Chrome-moly (CrMo) tubular upper and lower a-arms save an additional 8 pounds over stock
• Premium upper and lower ball joints pre-installed for worry-free installation
• Greaseable polyurethane bushings throughout for long service life
• Lower arms (P/N 2305) feature poly bushings on the straight strut section to absorb road noise
• Non-adjustable uppers guide suspension on greaseable poly bushings for smooth operation
• CrMo construction saves an additional 1.5 pounds per arm

Complete Bolt-In Installation:

• Direct bolt-in replacement requiring no welding or fabrication
• Includes all new grade 10.9 a-arm mounting hardware for secure installation
• Works with factory steering rack for hassle-free compatibility
• Manufactured in Philipsburg, Pennsylvania, USA

The Stage 2 kit removes significant front-end weight while enhancing performance and maintaining the street comfort needed for daily driving. All components are precision-bent, CNC-notched, and jig-welded from strong USA DOM tubing to ensure consistent quality and proper fitment. This kit provides the ideal upgrade for street cars that demand race-ready performance without sacrificing reliability.
