UMI Performance A224-250S Viking Front Coilover Kit Double Adjustable Bearing - 250lb

The UMI Performance A224-250S is a front coilover kit built in partnership with Viking Performance, combining a high-quality USA-made hybrid coil spring with a 19-position double adjustable shock absorber. Designed for drag racing, street driving, and road course/autocross use, this kit delivers professional-grade tunability and allows up to 3 inches of front ride height reduction without the need for a coil spring compressor.

Kit Contents:

• (2) Front coilover shocks — double adjustable compression and rebound
• (2) Front hybrid coil springs — 250 lb spring rate (this variant)

Spring Rate Options:

• 250 lb — 11" tall springs for drag race only; serious front-end lightening required
• 350 lb — Small block cruise or drag race with lightening required
• 450 lb — Small block cruise or big block drag race
• 550 lb — Small block handling; all big block applications except drag

Key Features:

• 19-way independent compression and rebound adjustment — 361 possible damping combinations to dial in street, strip, autocross, or road race performance
• Bearing-mounted lower attachment — increases reliability and performance for aggressive driving applications
• Hybrid coil spring design — upper coil fits the factory spring perch; lower coil mates to the coilover shock body
• No coil spring compressor required — the height adjuster functions as the compressor
• Brilliant protective finish — durable coating keeps springs looking great for years
• Every shock individually built, dyno tested, and serialized in Lakeville, Minnesota
• Rebuildable shocks — can be serviced at Viking or an authorized Viking rebuild center
• Compatible with UMI's geometry-corrected upper a-arm or the factory lower a-arm

Optional Accessories (sold separately):

• Spanner Wrench — used to adjust ride height with the shock in place; required for any height adjustment
• Thrust Bearing Kit — installs between the spring and spring seat for smoother, easier ride height adjustments; highly recommended

Lower Mounting Options: Viking offers two choices for the lower shock attachment. Polyurethane mounts are suited for mild street applications prioritizing ride comfort. Bearing-end mounts (this kit) are the correct choice for corner carving, drag racing, autocross, and road racing where reliability and precision are paramount. Note: performance mounts — both polyurethane and bearing — will feel and sound different than factory rubber-mounted components by design.
