Detailed Product Overview

Bilstein 24-027090 is a rear suspension shock absorber for Saab 9-5 models from 1999 through 2009. It is designed for use with aftermarket lowering springs, where standard OE-length dampers can lose effectiveness due to reduced ride height. The monotube construction supports stable damping performance, while the B8 Performance Plus valving is calibrated for improved handling response and a sportier stance on the Saab 9-5 rear suspension.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. If you are replacing worn rear dampers on a Saab 9-5, part number 24-027090 is a direct fitment reference to verify before ordering.

Common Problems This Part Addresses

• Rear suspension bounce or poor damping control
• Excessive body movement after lowering the vehicle
• Reduced rear-end stability during cornering
• Uneven ride quality caused by worn shock absorbers
• Loss of suspension control on lowered Saab 9-5 setups

Installation Notes and Tips

Install 24-027090 on the rear of 1999-2009 Saab 9-5 models only. Confirm the upper stem mount and lower 15 mm eye mount match the vehicle before installation. Because this damper is intended for lowered-spring applications, pair it with compatible aftermarket lowering springs rather than stock-height springs for proper suspension geometry and travel.

Quality Assurance

Bilstein tests each B8 Performance Plus damper to meet or exceed OE standards. Part number 24-027090 is part of Bilstein’s performance shock absorber lineup, built for consistent quality and application-specific fitment on the Saab 9-5 rear suspension.
