Energy Suspension 4.6101G Black Rear Spring Upper & Lower Isolator Set for 1979-2004 Ford Mustang & 1984 Mercury Capri

Fits 1979-2004 Ford Mustang (Base, GT, LX, SVO, Cobra, Mach 1) and 1984 Mercury Capri RS.

Replace worn, rotted, or sagging rubber spring seats with the Energy Suspension 4.6101G Rear Spring Upper and Lower Isolator Set. Factory rubber isolators often compress or disintegrate over time, leading to metal-on-metal contact and lost ride height. These isolators are manufactured from proprietary Hyper-Flex polyurethane, which is resistant to road contaminants and mechanical compression, lasting 3 to 10 times longer than standard rubber components.

Designed as a direct replacement for OE hardware, this kit installs into the factory chassis mounting points without altering the vehicle's original ride characteristics. They provide a stable, durable platform for the rear coil springs to seat against, helping to restore and maintain proper vehicle height.
