Upper a-arms add caster for improved steering feel and straight line stability. Adjustabilty means minimum shims.

Double adjustable Viking shocks are hand assembled in Minnesota USA and feature 361 possible valving combinations. Simply click and tune.

Hybrid coilover springs are available in various rates depending on application and are Made In USA

Rear trailing arms feature Poly and Roto-Joints as well as adjustable uppers for setting pinion angle and rear lateral location.

Choice of 1??????? or 2??????? rear lowering springs combined with Viking double adjustable rear shocks works great on street, auto-x and even the drag strip.

1??????? diameter tubular Pro-Tour style rear sway bar allows setting for street/handling or strip. Chassis mounted sway bar allows 3 adjustments.

Rear sway bar is preload adjustable to function as a drag anti-roll bar. Simply turn the on-car adjuster and leave the line with no body twist and even traction.

Who says you can't have it all? UMI's Stage 4 kit transforms your G-Body into a handling machine with the adjustability to perform well at the strip or haul your family comfortably - to the autocross. If drag racing is more your style, a few minor changes at initial purchase (or down the road) will have you launching with the best of them, then canyon carving on the way home! Up front we start with UMI's proven upper and lower tubular a-arms loaded with ??????????? taller upper and lower ball joints giving you a total of 1" increased spindle height. The adjustable upper a-arms increase caster, without additional shims, for a precise steering feel. The lower a-arms are loaded with UMI-built Delrin bushings for smooth non-binding motion and precise steering. Viking's new front hybrid coilover with double adjustable shock allows ride height, compression and rebound adjustment. The ride height adjustment is accomplished with the included spanner wrenches and thrust washers. The compression and rebound adjusters are clicked by hand (no tools!) and feature a total of 361 possible valving combinations. The front is completed by UMI????????s 1.250??????? CrMo handling sway bar. Out back we stiffen the chassis with adjustable tubular frame braces which stabilize the Poly/Roto combo lower trailing arms and fully adjustable Roto-Joint upper control arms. 1??????? or 2??????? lowering rear springs are controlled by Viking????????s double adjustable rear shocks, once again featuring 361 possible combinations. Rounding out the rear is our Pro-Tour style rear sway bar. This 3-way adjustable bar features 1??????? tubular construction, race style end links and UMI????????s proven CNC machined clamping system. One bar allows street, road race, auto-x and drag settings. As always, this kit features UMI????????s quality red or black powder coat and premium hardware. All UMI components are manufactured with pride in Philipsburg, PA ???????? USA.

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.
