Adjustability is one the most important things when tuning in your street car's suspension. Only the best materials and components money can buy were used to build UMI's "Ultimate Arms". Well known weak areas where other manufactures use mild steel have been replaced with aircraft quality 4140 chrome moly steel featuring a TIG welded construction. The upper control arm mounting points feature CNC machined 0.250" mild steel, 4140 Chrome-Moly tube adaptors and a high strength 4140 chrome moly heat treated 1.000" solid adjuster; truly overkill for any application!
For ease of adjustment UMI has designed our Ultimate Arms with on-car adjustability. You can easily make pinion angle adjustments in the garage or at the track; it's as simple as loosening two nuts! Using UMI's unique chrome moly on-car adjuster, simply turn the adjuster with the control arms on the car to quickly lengthen or shorten the control arm length. Pinion angle adjustments are a must when wanting to lower your track 60-foot times, increase traction and reduce unwanted wheel hop. Our QA1 Teflon lined spherical rod end design allows for a bind free operation, making a great upgrade for both your track and auto cross driven vehicle. Durable powder coat finish. Made in the USA.
