Restore proper front ride height and a controlled, level stance with the Mevotech Supreme Coil Spring Set (P/N SMS6446). It installs as a direct-fit replacement in the front suspension of the 1973 Cadillac Commercial Chassis and the 1973 Cadillac Fleetwood, swapping in for tired, sagging original springs.
Front coil springs carry the vehicle's weight, set ride height, and work with the shocks to absorb bumps and keep the tires planted. As springs weaken or sag, you may notice a lowered or leaning front stance, a harsh or bottoming ride over bumps, and uneven front tire wear — signs the springs may need replacing.
- Front application: engineered for the front suspension of the listed 1973 Cadillac models.
- Ride-height support: helps restore the factory front ride height and level stance.
- Sold as a set: supplied to service the front suspension for even, balanced results side to side.
If worn front springs are the cause of your sag or rough ride, this set replaces them. Always diagnose the cause before replacing worn springs.
