UMI Performance 3619-R Upper Control Arms - Adjustable Extended Length Rear Suspension

The UMI Performance 3619-R Extended Length Upper Control Arms are precision-engineered suspension components designed to properly center the rear wheels on Impala SS vehicles. These adjustable control arms feature a 5/8" extended length with an additional 1/2" of adjustability, allowing for perfect rear end alignment without removing the arms from the vehicle.

Key Features:

• CNC machined mounting points from 0.250" mild steel for exact tolerances and accuracy
• DOM tubing construction with 4140 Chrome Moly heat-treated adjuster
• High-strength chromoly spherical rod ends with Teflon/Kevlar self-lubricating race
• Energy Suspension greaseable polyurethane bushings for reliable performance
• Heat-treated and hard chrome-plated components for durability
• Easy on-car adjustments for length and pinion angle settings
• Durable glossy powder coat finish for long-lasting protection
• Ships pre-set at 5/8" extended length

These upper control arms utilize Teflon-lined rod ends that prevent metal-to-metal contact, eliminating unwanted noise for quiet operation. The 1.000" solid adjuster is manufactured from heat-treated 4140 Chrome Moly, providing exceptional strength for any application. Designed to work with extended length lower control arms for complete suspension geometry correction.

Important Installation Note: Depending on ride height variation, a longer driveshaft may be necessary when using extended length control arms.
