Upper Control Arms

Adjustability is one the most important things when tuning in your street car's suspension. That is why UMI has taken the time to develop the Ultimate "on car" adjustable upper control arms for the rear on your GM vehicle. There were no short cuts when manufacturing these arms, 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 over kill for any application!

This product is supplied with high quality QA1 spherical rod ends, alloy steel, heat treated, hard chrome plated featuring Teflon/Kevlar self lubricating race. Teflon lined rod end prevent metal to metal contact to eliminate unwanted noise allowing for a quiet operation not found with other brand rod ends. When purchasing rod ended components don't be fooled, use only the best-QA1, for a long lasting performance.

For ease of adjustment UMI has designed the 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 jam nuts! Using UMI's unique Chrome Moly on-car adjuster, simply turn the adjuster with the control arms on the vehicle 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. These QA1 Teflon lined spherical rod end designallows for a bind free operation making a great upgrade for both your track and auto cross driven car.

Lower Control Arms

Rear control arms are one of the most important suspension modifications that can be done to your GM vehicle. Stock control arms are on the borderline of junk, bushing deflection and rusting weak stamped material add for traction loss and poor handling ability. These boxed control arms are designed to give you the best of both worlds, whether your car is a weekend cruiser or a weekend track addict UMI has you covered. The included Energy Suspension polyurethane bushings are an excellent improvement over OEM rubber bushings, while adding ride improvements they also work excellent to reduce traction loss. These control arms are a direct bolt-on replacement designed to minimize wheel hop, improve cornering and help track consistency. Each control arm features the correct provisions for adding a stock or aftermarket sway bar. Sway bar holes are reinforced with a 0.120" wall thickness steel sleeve TIG welded and sanded into place. The construction of the control arms features 0.120" wall thickness rectangular tubing with CNC machined drawn over mandrel bushing holders and MIG welded end caps to keep out unwanted road debris.
