UMI Performance Stage 4 Front Suspension Packages

UMI Performance Stage 4 front suspension packages are direct bolt-in replacements–no welding is needed. These kits will give your vehicle a sturdy understructure, while providing weight reduction, performance, and comfort. The dual tube K-member and tubular upper and lower race A-arms and rod ends can take any abuse you can dish out. Poly bushings on the straight strut portion absorb road noise, while the non-adjustable uppers guide the suspension on greasable poly bushings.

Additional features:

* Premium upper and lower ball joints installed
* Double adjustable Viking shocks feature 361 possible valving combinations
* Height adjustment from 0 to 2 in. lowering
* 550 lbs./in. front springs
* 33 lbs. of front-end weight savings
* Chromoly A-arms save an additional 1.5 lbs.
* Work with factory steering racks
* Grade 10.9 hardware with Nyloc nuts
* Thrust bearing and spanner wrench
