<p>Our heavy-duty shock absorber is a high-performance, OEM replacement part for number 85979. It is compatible with Gabriel, Meritor,and Peterbilt. Our suspension shock absorber comes with an extended length of 31-3/16" and a collapsed length of 18-11/16". The suspension shock absorber provides superior control, comfort, and durability even in harsh conditions generally experienced during heavy-duty applications. It controls the movement of suspension springs and ensures that tires maintain contact with the road surface. It also helps to reduce tire wear, improve braking efficiency, enhance operator comfort, and extend the life of other suspension components.&nbsp;</p> <ul> <li><strong>Double Lip Oil Seal Design: </strong>This shock absorber is equipped with a high-precision Nitrile double lip oil seal that offers excellent resistance to wear, impact, and pressure. The seal prevents leaks by providing a superior radial seal, resulting in a longer product life. A cushion below the guider protects the piston from direct impact, further enhancing durability.</li> <li><strong>Proprietary Valve System: </strong>The shock's proprietary valve system utilizes a two-way structure design for better damping force control compared to traditional one-way valves. The durable and stable patented technology improves the performance of the piston and compression valve, while a carbon fiber wear ring enhances resistance to wear and temperature fluctuations.</li> </ul> <p><strong>Compatibility</strong><br>This shock absorber is compatible with Peterbilt applications and can replace OEM part number 85979. It also fits Gabriel and Meritor suspension systems and can be suitable for use in a wide range of heavy-duty trucks and trailers.</p> <ul> <li><strong>Fits Automann:</strong> A85979, AMA85979</li> <li><strong>Fits Gabriel:</strong> 85979, GBL 85979</li> <li><strong>Fits Hendrickson:</strong> 59305-1, 593051, 60675-002, 60675-002L, 60675-017, 60675002, 60675002L, 60675017</li> <li><strong>Fits Meritor:</strong> TDA M85979</li> <li><strong>Fits OE Aftermarket:</strong> 82785979</li> <li><strong>Fits PRT (ADD):</strong> 925406</li> <li><strong>Fits Rockwell International:</strong> M85979</li> <li><strong>Fits Sachs:</strong> 317943</li> </ul> <p><strong>Easy Installation</strong><br>Installing this shock absorber requires basic mechanical tools and knowledge of suspension systems.
