Product Details

This Dorman coil spring insulator, part number 540-896, is built for select Nissan Altima and Nissan Maxima rear lower suspension locations. It is made from rubber and measures 132 mm in length, 136 mm outside diameter, 59 mm inside diameter, and 10.5 mm thick. The specific-fit design helps match the original equipment shape and mounting style for a direct replacement on the intended vehicles. This part cross-references Nissan 550368J010 for the same application.

Common Issues It Can Help Address

• Noise from worn or hardened spring isolators
• Metal-to-metal contact between the coil spring and seat
• Suspension vibration transmitted into the chassis
• Uneven spring seating caused by deteriorated rubber
• Loss of original spring isolation at the rear lower position

Installation Notes

Install at the rear lower coil spring location on the listed Nissan applications. Inspect the spring seat and surrounding suspension components before installation, and replace any damaged mounting surfaces as needed. Verify vehicle year, model, and position before ordering or installation. Part number 540-896 is a specific-fit replacement, not a universal part.
