Front Conversion Kit for FWD Models

The Unity 31-140500 kit converts the front air suspension on 1985-1990 Buick Electra, 1986-1990 Buick LeSabre, 1986-1990 Cadillac Commercial Chassis, and 1985-1990 Cadillac Fleetwood models to a passive steel spring setup. It is intended for owners of these specific front-wheel-drive vehicles who want to eliminate air-ride components.

Replaces Factory Air Ride Components

This kit removes the original air springs, compressor, and associated plumbing that often develop leaks or electronic faults after decades of service. The conversion is worth it when the air system no longer holds pressure, when diagnostic costs exceed the price of a permanent mechanical fix, or when the owner prefers a simpler suspension that does not rely on sealed air bags.

Steel Springs Hold Ride Height Continuously

Once installed, the steel springs support the vehicle weight without the pressure cycling inherent to air systems. There is no compressor run time to monitor, no bag to rupture under load, and no height sensor to recalibrate. The suspension behaves the same whether the car sits parked for weeks or runs daily on rough pavement.

Questions about this item

Which front brake components does the Unity 31-140500 kit convert on a 1985-1990 Buick Electra?

The kit converts the front suspension from air ride to a passive steel spring setup on 1985-1990 Buick Electra FWD models, replacing the air spring assemblies with steel coil springs and matched shock absorbers.

What is the installation step most often missed when fitting the Unity 31-140500 front conversion kit?

Disabling the air ride compressor and electronic level control system before removing the original air springs is the step most often missed; the warning light will stay on if the system is not deactivated.

What maintenance does the Unity 31-140500 conversion kit require after installation?

The steel coil springs and shocks need no periodic inflation; inspect shock absorbers for leaks and check spring seats for corrosion during routine brake or tyre service intervals.
