Spring QM 5in x 1.63in ID 120lbs

The TANNER Spring QM 5in x 1.63in ID 120lbs coil spring is a precision-engineered suspension component designed for coil-over applications requiring a 120 lb/in spring rate. This spring is suitable for users building or upgrading coil-over suspension systems for light trucks, SUVs, and specialized tactical vehicles.

Constructed from durable steel and finished with an orange powder coat, this spring offers corrosion resistance and longevity in demanding environments. The 5-inch length and 1.63-inch inner diameter make it compatible with standard coil-over systems, ensuring reliable performance under load. The spring rate of 120 lbs per inch indicates that it compresses one inch for every 120 pounds of force applied, making it ideal for applications requiring controlled articulation.

Builders prioritize spring rate selection to match vehicle weight, intended use (patrol duty, rapid mobility, recovery operations), and terrain demands. The lightweight design minimizes unsprung weight, which is crucial for suspension tuning in both on-road handling and off-road performance. This spring is an excellent choice for those seeking to enhance their vehicle's suspension capabilities.
