UMI Performance
UMI Performance 1978-1988 GM G-Body Rear Adjustable Upper & Lower Control Arm Kit - 301417-B
$519.99
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1978-1988 GM G-Body vehicles, including Buick Regal, Chevrolet Malibu and Monte Carlo, Oldsmobile Cutlass, and Pontiac Grand Prix and LeMans.
Replace the flexible, stamped-steel factory suspension with the UMI Performance rear control arm kit. This comprehensive package includes tubular lower control arms and on-car adjustable "Ultimate Arms" uppers, designed to significantly increase chassis rigidity and provide the adjustability needed to dial in rear-end geometry. The on-car adjustable uppers allow for precise pinion angle tuning without disconnecting the hardware, while the heavy-duty tubular construction eliminates the wheel hop and bushing deflection common with OE setups.
- Direct replacement for factory rear upper and lower control arms
- On-car adjustable upper arms for easy pinion angle correction
- Single adjustable tubular lower control arms for increased strength
- Retains factory mounting points and uses OEM hardware
- Manufacturer Part Number: 301417-B
- Included Components: Tubular Lower Control Arms (Item #3014), Adjustable Upper Control Arms (Item #3017)
