10.5in x 5in x 325# Rear Spring

The Landrum Springs 10.5" x 5" x 325# Rear Spring is a precision coil spring engineered for suspension tuning on vehicles requiring consistent spring rate performance. Built from steel with a gold powder-coated finish, this rear spring delivers a 325 lb/in spring rate across its 10.5-inch length and 5-inch outer diameter, making it suitable for applications demanding controlled weight distribution and stable ride characteristics.

Landrum's Gold Series represents conventional coil spring design optimized for aftermarket and restoration work. The 325 lb/in rate strikes a balance between load support and compliance—stiff enough to manage body roll and squat during acceleration or braking, yet compliant enough to absorb road imperfections without excessive harshness. The gold powder coat provides corrosion resistance in environments ranging from street use to salt air exposure. Each spring is a single unit rated for rear axle duty, ensuring proper weight distribution when installed as part of a complete suspension system.

This rear coil spring suits vehicle owners performing suspension upgrades, restorations, or repairs where OEM-equivalent or performance-matched springs are required. Spring rate selection is critical—the 325 lb/in specification must align with front-end rates and vehicle weight to maintain proper geometry and handling balance. Technicians and enthusiasts typically pair rear springs with matching front springs and complementary dampers to achieve integrated suspension performance.

Proper installation requires removing the vehicle from service, supporting the frame safely, and compressing the spring with appropriate tools before seating it in the spring seat. Consult your vehicle's service manual or suspension specialist to confirm this spring's compatibility with your specific make, model, and year before ordering.
