Detailed Description

Monroe 58606 is a suspension shock absorber and coil spring assembly engineered for rear applications where payload and trailer weight can vary from trip to trip. The calibrated spring adds support as the rear suspension compresses, helping the vehicle respond more consistently under load. This makes it a practical choice for Chevrolet Express 1500, GMC Savana 1500, Chevrolet Tahoe, and other listed rear-fit applications from 1992-2014.

The shock measures 14 inches compressed and 22.375 inches extended, with 8.375 inches of travel. It also includes a metal dust shield and an extended bumper stop for added protection in demanding service. This part cross-references Monroe Shocks & Struts 43180 and 51929 for the same application.

What It Helps Address

• Rear sag when towing trailers or carrying cargo
• Excessive bounce after load changes
• Reduced rear-end control on uneven roads
• Inconsistent ride height under varying payloads
• Wear from frequent towing and hauling duty
