Up front we start with UMI's proven upper and lower tubular a-arms loaded with ½ taller upper and lower ball joints. The 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 includedner wrenches and thrust washers.

All UMI components are manufactured with pride in Philipsburg, PA USA. Increased spindle height by 1 via tall upper and lower ball joints for improved camber gain and a better contact patch. Upper a-arms add caster for improved steering feel and straight line stability. Lower a-arms feature UMI-built Delrin bushings and accept standard springs or coilovers.

1.250 front sway bar for flat cornering, CNC bent from 4140. Double adjustable Viking shocks are hand assembled in Minnesota USA and feature 361 possible valving combinations. 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.

UMI lower A-Arms are fabricated from DOM tubing with CNC machined tube ends for a precision fit. They are jig built to maintain accuracy and bolt on correctly every time. All critical areas are TIG welded for superior strength and a clean look.

UMIs lower A-Arms also feature improved ball joint angle for lowered vehicles and the design provides additional tire clearance. Lower a-arms include greaseable, UMI designed and manufactured Delrin bushings.

Delrin bushings offer supremely smooth suspension action and precision operation while still providing some insulation from road noise. They come preloaded with polyurethane bump stops, steering stops and premium ball joints. UMIs extensive testing on the street, drag strip and skid pad ensures a quality product able to with stand all types of abuse. UMI lower A-Arms are designed to work with factory springs, lowering springs and coil over kits without changing the a-arms.

Fits factory spindle and works with factory springs, lowering springs and coil over kits. Durable red or black powder coat finish.

Each kit includes new Energy Suspension end links and greaseable sway bar bushings with new zinc plated clamshells. Sway bar is available powder coated bright red or gloss black for a durable long lasting finish. This beefy 1 solid rear sway bar is designed to reduce body roll, understeer and increase corning capabilities resulting in a more balanced suspension.

The Roto-Joint design is a pivot ball lined with a greaseable delrin race designed to offer 28 degrees of total unrestricted movement, more than adequate for a bind free, low friction operation. The installed delrin race, which lines the spherical ball, absorbs shock and road noise for a quiet and smooth operation on any street or track driven vehicle. This control arm set features polyurethane bushings on one end and UMIs swivel Roto-Joint on the other end. This set-up is designed for street performance and street enthusiast. The polyurethane bushing end is designed to be bolted to the vehicle chassis side while the Roto-Joint attaches to the rear end side.

Since the polyurethane bushings are softer they are designed to absorb more road noise and shock before it enters the passenger compartment of the vehicle. Both control arms feature the correct provisions for adding a stock or aftermarket sway bar. Sway bar holes are reinforced with a 0.120 wall thickness steel sleeve that is TIG welded and sanded into place. All bushing ends and Roto-Joints are greaseable and low maintenance making an excellent street setup for your cruiser!

Constructed of 1.500 x 0.120 DOM mild steel tubing. Energy Suspension greaseable polyurethane bushings.

Brilliant and durable powder coat finish. Trailing arm mount braces are designed to reinforce the rear upper and lower front control arm mounts on your 78-88 G-Body vehicle. The more power your ride makes the better chance of bending or breaking the rear control arm mounts. These tubular reinforcements tie the upper and lower rear control arm mounts together for added strength and driving performance. The UMI Performance braces are bent to contour the floor of the vehicle, unlike some competitors designs these reinforcements do not require the floor to be dented or pounded for correct fitment.

Pinion angle adjustments can easily be made in the garage or at the track and making adjustments is as simple as loosening two jam nuts. Using UMIs chrome moly on car adjuster, simply turn the adjuster with the control arms attached to the vehicle to quickly lengthen or shorten the control arm. As the control arms are shortened or lengthen the rotate the rear end changing the pinion angle.

Polyurethane Rear End Housing Replacement Bushings. Replace your rubber OEM rear end housing with an Energy Suspension polyurethane setup. Over years, rubber OEM bushings dry rot, crack and harden, decreasing your ride quality and performance.

The Energy Suspension polyurethane bushings replace the two upper control arm rear end differential bushings--the bushings that stay attached to the rear end. This is an excellent upgrade for your street or track driven vehicle. UMI's Roto-Joint, short for Rotational Joint, allows 28 degrees of total rotation and unrestricted movement throughout the vehicles suspension. The Roto-Joint is designed to work like a spherical rod end while maintaining streetable qualities of a softer bushing. The Roto-Joint is designed to articulate and prevent suspension bind, and since the installed delrin race does not deflect like softer bushings, there is an improvement in traction and a significant reduction in wheel hop.

The UMI Roto-Joint is adjustable and 100%25 rebuildable. This means as the delrin race wears the adjuster ring can be tightened using the optionalner wrench to apply tension to the ball. If the delrin race would ever wear completely it can be replaced easily.ner Wrench Thisner wrench is used for adjusting and disassembling Roto-Joints used in all UMI Performance products. Over time if the delrin race inside the Roto-Joint would wear thener wrench is used to tighten the adjusting ring applying more pressure to the delrin inside.

Thener wrench is also used to disassemble the Roto-Joint for cleaning, inspection and rebuilding. Greaseable unit increases bushing life. 28 Degrees of total unrestriced movement.
