Product Details

The PRT Shock Absorber line focuses on replacement suspension components for everyday drivability and OE-style fit. This rear shock absorber uses a bolt upper mount and loop lower mount, with center-of-bolt and center-of-loop measuring points for accurate application matching. The gas-charged construction helps maintain damping consistency, while the included metal dust shield adds protection to the shock rod area. PRT Performance Ride 373320 is a direct-fit rear shock absorber for 2008-2015 Scion xB, 2010-2015 Toyota Prius, and 2012-2015 Toyota Prius Plug-In rear suspension service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Replacement Reasons

• Rear suspension noise over bumps or rough pavement
• Excessive bouncing after dips, braking, or lane changes
• Reduced ride control in the rear of the vehicle
• Uneven rear suspension response from worn shock damping
• Visible wear to the existing rear shock absorber or dust protection

This shock uses a loop lower mount and bolt upper mount, so confirm the vehicle’s original rear shock configuration matches the listed dimensions and mount points. Inspect related suspension hardware, bushings, and mounting surfaces during replacement, and torque all fasteners to the vehicle manufacturer’s specifications.
