UMI Performance 1978-1988 Lowering Spring Kit, 2 Lowering
$319.99
  • Nfloatingg.
  • Suitable for Pro-Tour, Auto-x and general cruising.
  • ManufactureUSA

Consistent rates and only the best materials (premium Chrome Silicon wire) ensure your cars sits properly for years to come.

Linear spring rates (600 lb/in front, 130 lb/in rear) provides a firm yet comfortable ride and incredible handling.

A spring is a spring right? Wrong! When UMI chose to manufacture our own line of springs we went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these springs are the best in the business. Our front springs are wound from 5160 CrSi premium wire and feature a linear 600 lb/in rate. The rear springs are wound from 9254 CrSi premium wire and feature a linear 130 lb/in rate. The linear rate provides consistent handling characteristics which are important for Auto-x and Pro-Tour applications while the increase in stiffness reduces body roll and prevents the floating feeling so common with the G-Body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising. The ride height is engineered for a 2 Lowering with standard SBC as well as LS power (lightened cars may require spring trimming). The front springs are also suitable for full weight Big Block applications when nose down rake is desired. They have a tough, black powder coat finish and UMI proudly manufactures these premium quality springUSA.

Who is UMI Performance?

UMI Performance is an aftermarket company that specializes in building high-quality suspension parts. But before they were known as a suspension manufacturer, they manufactured precision parts for major brands such as Corning Asahi, Sony, and Bell+Howell. They may have shifted industries, but their dedication to creating quality products has remained the same.

Quality Products Made In The USA

All of their products are made in-house, which allows them to control every aspect of their products. 100% made in the USA, they can maintain their high standards and create suspension parts that can tackle any street, whether it be the fast corners of a race track or the bumpy road to your grocery store.

Parts Bred From The Racetrack

UMI Performance actively participates in various racing disciplines since most of their product engineers and sales team are racers. Because of this, they can test their products through real-life racing scenarios, which helps them gather data that can help improve their products.

Easy To Install Parts

Each product is designed to replace factory-installed parts without any significant modification. It is carefully measured to ensure that it would fit perfectly into the vehicle and comes with a step-by-step instructional manual, giving their customers a hassle-free installation experience.
