UMI Performance 70-81 F-Body 78-96 B-Body Viking Front Coil Over Kit Double Ad- Poly

If you're looking to dial in the suspension on your 1970-1981 F-Body or 1978-1996 B-Body vehicle, this Viking front coilover kit from UMI Performance is a solid option. This kit combines a hybrid coil spring with a 19-position double adjustable shock, allowing you to fine-tune your ride height and damping characteristics. It's designed to work with UMI's lower A-arms or your factory lower A-arms, and pairs well with UMI's geometry-corrected upper A-arms for a complete suspension upgrade.

The beauty of this coilover system is its adjustability. You get independent control over compression and rebound damping, giving you the flexibility to set up your car for everything from daily driving to autocross or even drag strip duty. The kit allows for ride height adjustments from stock down to a 3-inch drop, and you can choose from several spring rate options to match your intended use, whether it's for a small block cruise, big block drag car, or a handling-focused setup. The shocks are built, dyno-tested, and serialized in Minnesota, ensuring a well-built component.

For easier ride height adjustments, UMI recommends the optional spanner wrench and thrust bearing kit. The thrust bearing goes between the spring and the spring seat, making it much smoother to turn the adjuster nut. The polyurethane lower shock mounts offer a good balance of comfort and performance for street use, though bearing ends are recommended for more aggressive applications like road racing or autocross for increased reliability. This kit is a significant upgrade for those serious about optimizing their classic GM suspension.
