Product Details

The PRT Performance Ride suspension strut and coil spring assembly is part of the PRT Suspension Strut and Coil Spring Assembly line, a product line focused on complete strut-and-spring replacement for specific vehicle applications. This rear assembly is engineered around the listed fitments for Lexus IS250 and Lexus IS350 models, helping maintain the original suspension layout while replacing a worn rear unit with a matched strut and spring design. Part number 920133 is specified with a bolt upper mount, loop lower mount, and regular grade construction.

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

Common Reasons for Replacement

• Rear suspension noise from a worn strut assembly
• Loss of rear ride control or stability
• Sagging rear stance caused by spring fatigue
• Uneven rear tire wear related to suspension wear
• Reduced damping performance from an aging rear strut

Installation Notes and Tips

Verify rear fitment by year and model before installation. This assembly uses a bolt upper mount and loop lower mount, so confirm the mounting points match the vehicle before removal of the original unit. Because mounting hardware is not listed as included, reuse or replacement hardware should be confirmed during service. After installation, a suspension inspection and alignment check are recommended if other rear suspension components were disturbed.

Quality Assurance

PRT Performance Ride identifies this assembly with a dust shield and standard non-adjustable damping configuration for the listed Lexus applications. Part number 920133 is built for the specified rear fitments and suspension layout.
