Detailed Product Overview

Arnott AS-2125 is engineered for rear suspension service on Cadillac DeVille, Eldorado, and Seville models that originally used electronic shocks. The kit converts the system to a more dependable passive air shock arrangement while preserving rear air leveling function. Its twin-tube, hydraulic design and progressive spring rate support consistent rear suspension response, and the included relay/wire harness addresses the electronic bypass required for proper operation.

This part cross-references Cadillac OE numbers 22064565 and 22400392 for the same application. If you are replacing a rear air shock absorber on a 1993 Cadillac Eldorado, 1993 Cadillac Seville, or 1994-1995 Cadillac DeVille, AS-2125 provides the correct fitment and suspension layout for those rear positions.

Common Problems This Part Can Address

• Rear shock failure on electronically controlled Cadillac suspension systems
• Inconsistent rear ride height from worn air shock components
• Fault codes related to the SSS speed-sensitive suspension module
• Loss of rear damping performance over rough roads
• Air suspension noise or degraded ride quality from aging rear shocks

Installation Notes

Fits 1994-1995 Cadillac DeVille, rear. Fits 1993 Cadillac Eldorado, rear. Fits 1993 Cadillac Seville, rear. Verify rear suspension configuration before installation and confirm the vehicle uses the electronic shock setup referenced in the fitment notes. Mounting hardware is not listed as included, so reuse or source the required hardware as needed. The lower mount uses a loop/eyelet design and the upper mount uses a stud, so alignment during installation should match the original suspension layout.
