FBS005 – 1998-2002 GM F-Body LS1 Front End Kit, Drag, Stage 5

UMI’s Stage 5 kit offers a solid foundation for your strip car with occasional street use. Our dual tube k-member is recognized as the strongest in its class, capable of handling wheel stand landings and street abuse while reducing weight and protecting the oil pan. The rod end upper and lower a-arms minimize friction and unsprung weight, ensuring quick weight transfer. UMI’s k-member and a-arms are constructed from durable USA DOM tubing, precision bent, CNC notched, and welded in a jig to create a robust base. The upper and lower a-arms are assembled with Teflon-lined race-quality rod ends and premium ball joints. The adjustable a-arms enhance strength, reduce weight and friction, and allow for alignment adjustments when needed. Increased caster for straight-line stability is easily achieved with this bolt-in system.

Stage 5 includes Viking A226 bearing-mounted front coilovers with double adjustable shocks, allowing for ride height, compression, and rebound adjustments. The A226 features bearing ends instead of polyurethane, reducing friction and improving response and longevity. Ride height is adjusted using the included spanner wrenches and thrust washers. The compression and rebound adjusters can be clicked by hand (no tools needed) and offer a total of 361 possible valving combinations. The included springs are 300 lb/in, making them ideal for drag racing applications and vehicles with front-end weight reduction. The UMI Stage 5 kit is used in many single-digit F-body cars.
