What makes these control arms 'Ultimate Arms'?

The 'Ultimate Arms' designation comes from UMI Performance's use of premium materials and construction methods. This includes aircraft-quality 4140 chromoly steel, heat-treated adjusters, and high-strength QA1 rod ends, which are considered overkill for most applications but ensure durability and performance.

What is the benefit of 'on-car adjustability'?

On-car adjustability means you can make suspension alignment changes without removing the control arms from the vehicle. This significantly simplifies the tuning process, allowing for quicker adjustments to optimize handling for street driving or other conditions.

What is included with these control arms?

The product includes the adjustable upper control arms. It is recommended to consult the manufacturer's installation instructions for any additional hardware or components that may be required for proper installation on your specific vehicle.

Product Details

UMI Performance is known for making well-built suspension components for American muscle cars. If you're working on a 1978-1988 GM G-Body vehicle like a Chevrolet Monte Carlo, Buick Regal, or Pontiac Grand Prix, these Ultimate Adjustable Upper Control Arms are designed to help you dial in your suspension setup. Having the ability to adjust your suspension on the car makes tuning much easier, allowing you to fine-tune handling for street driving.

These arms were built with durability and performance in mind, using strong materials where other manufacturers might use weaker steel. The main tubes are aircraft-quality 4140 chromoly steel, and the adjuster is a heat-treated 1.000-inch solid chromoly piece. They also feature QA1 3/4-inch hard chrome-plated, Teflon/Kevlar self-lubricating rod ends for smooth operation. The mounting points are precisely machined from mild steel and include CNC machined 6061 aluminum step bushings, all finished with a durable powder coat.
