Product Line Details

Bilstein B8 TerraSport is the brand’s tuning-focused suspension line for CUVs that need added ground clearance without giving up everyday drivability. Each application is tested and tuned for the vehicle it serves, with the goal of balancing lift, control, and durability for mixed on-road and off-road use. If you are searching for a Bilstein shock absorber for Subaru Crosstrek rear suspension service, part number 24-320221 is the application-specific option in this series.

Detailed Description

Bilstein 24-320221 is a B8 TerraSport rear shock absorber engineered for 2016-2017 Subaru Crosstrek and 2013-2015 Subaru XV Crosstrek rear suspension applications. This shock is designed to provide 1.5 inches of rear lift on the listed vehicles while maintaining a controlled ride for daily driving, gravel roads, snow travel, and back-country routes. The monotube construction supports consistent damping performance, and the direct-fit layout simplifies replacement on the rear of the vehicle. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What It Helps Address

• Rear suspension sag on lifted Subaru Crosstrek and XV Crosstrek setups
• Reduced ground clearance on rough roads, trails, and snow-packed terrain
• Loose or inconsistent rear damping after shock wear
• Loss of control when carrying gear or traveling on uneven surfaces
• Need for a direct-fit rear shock with application-specific lift

Installation Notes and Tips

Compatible With 2016-2017 Subaru Crosstrek, rear; and 2013-2015 Subaru XV Crosstrek, rear. Verify rear suspension configuration before installation and compare the collapsed and extended lengths to the original part. The upper stem and lower eye mount design should be matched to the vehicle’s existing mounting points. Part number 24-320221 is listed for rear position only.

Quality Assurance

Bilstein tests and tunes B8 TerraSport shocks for each application, with attention to fit, ride quality, and durability. The monotube design and vehicle-specific calibration support consistent performance for Subaru Crosstrek and Subaru XV Crosstrek rear suspension service.
