UMI's new Stage 5 kit includes all of our high-end Pro-Touring products and will turn your A-body into a corner carving machine. Up front we start with UMI's awesome 4056-3 adjustable a-arm loaded with a 0.9" taller ball joint. This arm increases caster to around six degrees andallows road race camber settings with no shims. The lower a-arms are loaded with UMI-built Delrin bushings for smooth motion and precise steering as well as 0.5" tall lower ball joints to further increase spindle height and get rid of the factory bump steer. The 1.4" of additional spindle height transforms the A-body camber curve into something race worthy. Viking's front hybrid coilovers with double adjustable shocks 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 double Roto-Joint lower trailing arms and fully adjustable Roto-Joint upper control arms. With UMI's 2999 axle housing Roto-Joints, we end up with full articulation in all 8 locations. 1" or 2" UMI rear lowering springs (please specify at checkout) are controlled by Viking's double adjustable rear shocks, once again featuring 361 possible combinations. Rounding out the rear is our ?three way adjustable 1" tubular Pro-Tour sway bar. This handling sway bar attaches to the axle housing and also to the rear crossmember for a bind-free system (requires drilling four 3/8" holes). 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.

More about Roto-Joint Technology

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 construction of the Roto-Joint features a 4140 chrome moly, hard chrome plated spherical ball which rotates in a delrin race. The 4140 chrome moly material and hard chrome plating are designed for extensive wear resistance against hard driving and accumulated miles. The spherical ball rotates in the CNC machined delrin bushing, which is contoured for the spherical ball to allow unrestricted movement as the ball rotates. Delrin is the bushing material of choice due to its high resistance against wear, great tensile strength, and ability to maintain its physical properties. The housing of the Roto-Joint features 4140 chrome moly threads, and a CNC machined bushing holder TIG welded together for the utmost in strength and durability. 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 optional spanner wrench to apply tension to the ball. If the delrin race would ever wear completely it can be replaced easily.

Spanner Wrench
This spanner 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 the spanner wrench is used to tighten the adjusting ring applying more pressure to the delrin inside. The spanner wrench is also used to disassemble the Roto-Joint for cleaning, inspection and rebuilding.
