UMI Performance FBS005-B Stage 5 Front End K-Member & Suspension Kit Black

The UMI Performance FBS005-B Stage 5 Front End Kit is a comprehensive, race-engineered front suspension package built for serious drag racing with occasional street use. This complete bolt-in system eliminates the factory front suspension and replaces it with a purpose-built tubular dual-tube K-member, adjustable A-arms, and Viking double-adjustable coilovers — delivering 43 lbs. of front-end weight savings and a dramatically improved suspension geometry for straight-line performance.

The heavy-duty dual-tube K-member is CNC-notched, precision-bent, and welded in a jig using strong USA-made DOM tubing, and is recognized as one of the strongest designs in its class. It is capable of handling wheel stand landings and everyday street abuse while still reducing weight and providing improved oil pan protection. The kit is a direct bolt-in replacement requiring no cutting or welding, and retains compatibility with the factory steering rack.

• Heavy-duty dual-tube K-member construction — direct bolt-in, no welding required
