Unity Front and Rear Complete Strut Kit

This Unity kit contains four fully assembled strut assemblies, two for the front and two for the rear. It is designed for DIY mechanics and professional technicians who want to restore ride quality on compatible GM H-body sedans without sourcing individual components. The pre-assembled units arrive ready to bolt on, eliminating the need for a spring compressor or specialty tools during installation.

Replaces Worn Original Suspension

The assemblies replace factory struts that have lost damping control or suffered spring sag after decades of service. Upgrading is worth it when the vehicle exhibits excessive bounce, nose-dive under braking, or uneven tyre wear linked to tired suspension. Because every component — strut, top mount, bearing plate, bumper, insulators, and coil spring — is new, the repair returns the chassis to its original geometry in a single step.

Limited to Listed GM H-Body Applications

Fitment is restricted to the 1985 Cadillac DeVille, 1987 Cadillac DeVille, 1986 through 1990 Buick LeSabre, and 1986 through 1990 Oldsmobile Delta 88. Vehicles outside this model range, including later front-wheel-drive platforms or models with electronic ride control, cannot use these assemblies. Buyers must verify the exact year and model before purchase to avoid ordering parts that will not mount.

Questions about this item

Will the kit bolt to the factory mounting points on my 1987 Cadillac DeVille without modification?

Yes, the assemblies are OE-style and designed for direct fit on the 1986-1990 Buick LeSabre, 1985 Cadillac DeVille, 1987 Cadillac DeVille, and 1986-1990 Oldsmobile Delta 88.

Do I need a spring compressor to install these pre-assembled struts, or can I skip that step?

The kit arrives fully assembled with coil spring, top mount, bearing plate, bumper and insulators, so no spring compressor or specialty tools are required.

What components in the box will eventually wear out and need replacement?

Each assembly contains a strut cartridge, coil spring, top mount, bearing plate, bumper and insulators; the strut cartridge and mount components are the items that typically require future service.
