67-88 GM A/G-Body Rear 2in Lowering Spring Set

The 67-88 GM A/G-Body Rear 2in Lowering Spring Set from UMI PERFORMANCE is purpose-built for enthusiasts seeking a refined stance and improved handling geometry on classic and muscle cars. Whether you're restoring a Chevrolet Monte Carlo, Pontiac Grand Prix, or Oldsmobile Cutlass, this coil-over conversion addresses the factory suspension's limitations and delivers a modernized suspension platform. A 2-inch rear drop is the sweet spot for A/G-Body vehicles—aggressive enough to transform appearance while maintaining ride quality and driveline clearance without binding or bottoming concerns during spirited driving.

These lowering springs employ progressive-rate engineering to maintain compliance at ride height while resisting body roll during cornering and acceleration. The 2-inch drop reduces your center of gravity and shifts weight transfer dynamics, resulting in crisper turn-in and reduced understeer on factory or mildly upgraded suspension. UMI PERFORMANCE springs are manufactured to OEM tolerances and designed to work seamlessly with original dampers during initial installation or with upgraded shocks for enhanced performance. The robust construction handles daily driving stress and repeated suspension articulation without sagging or loss of preload over extended use.

This rear spring set is ideal for owners transitioning from factory suspension to a more aggressive stance while preserving rideability and longevity. Installation pairs easily with front lowering springs to achieve balanced, level stance across the entire platform. No cutting, welding, or frame modification is required—direct bolt-on fitment to original mounting points ensures straightforward DIY installation or professional shop setup. Compatibility spans all 67-88 A/G-Body platforms, including Chevelle, Malibu, and Grand Am variants, making this an essential upgrade for comprehensive suspension builds.
