Detailed Description

PRT Performance Ride 171376 is a rear shock absorber for GM minivan platforms that require a loop-to-loop mounting style. With 13.11 inches compressed length, 20.87 inches extended length, and 7.76 inches of stroke, it is sized for the rear suspension geometry used on the listed Chevrolet Uplander, Pontiac Montana, Buick Terraza, Saturn Relay, Oldsmobile Silhouette, and Pontiac Trans Sport applications. The gas-charged design supports consistent damping response, while the metal dust shield helps protect the rod area from road debris.

This PRT Shock Absorber part number 171376 is a practical replacement for rear ride control service where the original shock uses center-of-the-loop measuring points at both ends. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
