UMI Performance 1978-1996 GM B-Body Boxed Lower Control Arms- w/ Dual Roto-Joints - 3627-B
  • Features:
  • Constructed of 3????? x 1-1/2????? x 1/8????? rectangular steel tubing
  • MIG and TIG welded construction for superior strength
  • CNC machined for accurate tolerances and perfect fit
  • Spherical Roto-Joints installed for a bind free performance
  • Reinforced sway bar holes
  • Shipped fully assembled and ready to install
  • Uses OEM hardware
  • Brilliant and durable powder coat finish

UMI's boxed lower control arms utilize our Roto-Joint technology for a bind free performance and quiet comfortable ride quality. The boxed control arms are fabricated from 0.120????? wall thickness rectangular tubing, CNC machined drawn over mandrel bushing holders and MIG welded end caps to keep out unwanted road debris. Each control arm features the correct provisions for adding a stock or aftermarket rear sway bar, sway bar holes are reinforced with a 0.120????? wall thickness steel sleeve that is TIG welded and sanded into place. The solid construction combined with the delrin lined Roto-Joints eliminate control arm flex and bushing deflection for improved traction and reduced wheel hop. The Roto-Joint design is a pivot ball lined with a greaseable delrin race designed to offer 28 degrees of total unrestricted movement, more than adequate for a bind free, low friction operation. The Roto-Joint design improves performance over the factory rubber and aftermarket polyurethane bushings by allowing the suspension to articulate correctly, and provide precision handling. The installed UMI Roto-Joint allows rear end free movement when high handling, auto cross or road race is a concern while still being a 100% streetable setup. The installed delrin race, which lines the spherical ball, absorbs shock and road noise for a quiet and smooth operation on any street or track driven vehicle. This control arm set features Roto-Joints on both sides of the control arms. This is designed for maximum performance and suspension travel. Roto-Joints are greaseable and low maintenance making an excellent street setup for your cruiser or race car!

Who is UMI Performance?

UMI Performance is an aftermarket company that specializes in building high-quality suspension parts. But before they were known as a suspension manufacturer, they manufactured precision parts for major brands such as Corning Asahi, Sony, and Bell+Howell. They may have shifted industries, but their dedication to creating quality products has remained the same.

Quality Products Made In The USA

All of their products are made in-house, which allows them to control every aspect of their products. 100% made in the USA, they can maintain their high standards and create suspension parts that can tackle any street, whether it be the fast corners of a race track or the bumpy road to your grocery store.

Parts Bred From The Racetrack

UMI Performance actively participates in various racing disciplines since most of their product engineers and sales team are racers. Because of this, they can test their products through real-life racing scenarios, which helps them gather data that can help improve their products.

Easy To Install Parts

Each product is designed to replace factory-installed parts without any significant modification. It is carefully measured to ensure that it would fit perfectly into the vehicle and comes with a step-by-step instructional manual, giving their customers a hassle-free installation experience.
