Unity Front Rear Complete Strut Assembly

The Unity 4-11040-65390c-001 is a preassembled front and rear strut assembly designed for 1990-1999 Buick LeSabre, 1991-1993 Cadillac Deville, 1991-1992 Cadillac Fleetwood, 1992-1999 Oldsmobile 88, 1990-1991 Oldsmobile Delta 88, and 1997-1998 Oldsmobile Regency models. It includes OE-style strut, top mount, bearing plate, bumper, insulators, and coil spring. This kit suits DIYers and shops replacing worn suspension on these specific GM platforms.

Replaces Air Ride with Passive Suspension

The Elite Suspension Line converts factory air-ride systems to a nitrogen gas-charged twin-tube shock setup with coil springs. The jump is worth it when the original air suspension leaks, the compressor fails, or owners want to eliminate recurring air-line and sensor faults. It is not for buyers who want to keep the factory air-ride functionality or who need adjustable damping.

Installs Without Specialty Tools

The complete assembly arrives ready to bolt on, removing the need for spring compressors or separate component assembly. Common issues include seized lower mounting bolts, corroded upper strut tower nuts, and mismatched hardware if the vehicle was previously modified. Verify fitment against the listed model years before starting the job.

Questions about this item

Does the Unity 4-11040-65390c-001 strut assembly include the top mount and coil spring for direct installation?

Yes, the Elite Suspension Line kit includes an OE-style strut assembly, top mount, bearing plate, bumper, insulators, and coil spring preassembled so no specialty tools are required.

What is the most common mistake when installing this complete strut assembly on a 1990-1999 Buick LeSabre?

Installers often forget to torque the top-mount nuts to specification after compressing the spring, which can lead to noise or premature bearing wear.

Which components of the Unity 4-11040-65390c-001 will need replacement after extended use on a 1991-1993 Cadillac DeVille?

The nitrogen gas-charged shock cartridge, coil spring, bump stop, and bearing plate are wear items that will eventually require replacement.
