UMI Performance 3620-B Upper Control Arms Adjustable Extended Length

UMI Performance's 3620-B upper control arms are precision-engineered extended length control arms designed to properly center the rear wheels in the wheel well of Impala SS vehicles. These control arms come pre-set at 5/8" extended length with an additional 1/2" of on-car adjustability, allowing you to perfectly position your rear axle without removing the control arms from the vehicle.

Key Features:

• CNC machined and contoured mounting points from 0.250" mild steel for exact tolerances and accuracy
• DOM tubing construction for superior strength and durability
• 4140 Chrome Moly heat treated 1.000" solid adjuster for maximum strength
• 4140 Chrome Moly tube adaptors for enhanced durability
• Pre-set at 5/8" extended length with additional 1/2" adjustment range (lengthening or shortening)
• Energy Suspension greaseable polyurethane bushings for quiet, comfortable operation
• Easy on-car adjustments for length and pinion angle settings
• Durable glossy powder coat finish for long-lasting corrosion protection

These extended length upper control arms are engineered to work with extended length lower control arms for complete rear suspension geometry correction. The heavy-duty construction with heat-treated Chrome Moly components provides strength that exceeds the demands of any application. Note that depending on ride height variation, installation of a longer driveshaft may be necessary when using extended length control arms.
