UMI Performance A205-350R Viking Front Coilover Kit Double Adjustable Polyurethane Spring - 350lb

The UMI Performance A205-350R is a front coilover kit pairing a high-quality USA-made hybrid coil spring with a Viking 19-position double adjustable shock absorber. Designed for street, drag, autocross, and road race applications, this kit delivers a versatile and tunable front suspension solution with up to 3 inches of ride height adjustment range without requiring a coil spring compressor.

Each shock is individually built, dyno tested, and serialized at Viking's facility in Lakeville, Minnesota, ensuring consistent quality and traceability. The bearing-mounted bottom shock attachment increases reliability and performance compared to standard rubber mounts, and shocks can be rebuilt at Viking or an authorized Viking rebuild center.

Front Spring Rate Options:

• 250 lb – 11" tall springs for drag race only; serious weight reduction 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 blocks except drag; allows up to 2" lowering
• 650 lb – Small block and big block handling, autocross; allows up to 2" lowering

Kit Includes:

• (2) Front double adjustable coilover shocks
• (2) Front hybrid coil springs in the selected spring rate

19-Way Double Adjustable Damping: The Viking shock features independent compression and rebound adjusters with 19 positions each, yielding up to 361 possible tuning combinations. This allows precise customization for street cruising, drag racing, autocross, or road course use — all from a single shock.

Spanner Wrench & Thrust Bearing Kit (Optional): The spanner wrench adjusts vehicle ride height while the shock remains mounted. The thrust bearing kit, placed between the spring and the spring seat, allows the seat to rotate on a bearing for significantly easier height adjustments. This kit is strongly recommended but not required for installation. Height adjustment without a thrust bearing kit is not recommended.

Polyurethane Lower Shock Mount: This kit uses polyurethane for the lower shock attachment, suited for mild street applications offering improved ride comfort over bearing-end mounts. For aggressive corner carving, drag racing, autocross, or road racing, a bearing-end mount is recommended. Performance bushings — poly or bearing — may produce different NVH characteristics compared to factory rubber-mounted components.

Viking coilovers are compatible with UMI's lower control arm or the factory lower control arm. For a complete front suspension upgrade, pair with UMI's geometry-corrected upper control arm featuring a tall ball joint. The protective finish on the hybrid springs is designed to maintain appearance and resist corrosion over years of use.
