This pair of extra-heavy-duty coil springs is engineered specifically for select Dodge Ram 1500 models from 2009-2018.

Key Features:

• Constructed from high-strength 5160H alloy steel with durable powder coat finish for maximum longevity and corrosion resistance
• Variable spring rate design with 0.687-inch wire diameter for optimal load distribution
• Pigtail over center end configuration with semi-closed plain opposite end
• XHD (Extra Heavy Duty) suspension grade with 16-inch height and +2.9-inch OE lift
• Package includes 2 coil springs (pair) for complete rear axle replacement
• Custom-engineered to improve ride quality, reduce driver fatigue, and improve handling with quality steel manufacturing

These springs are ideal for pickup trucks, SUVs, RVs, plow trucks, and vans that require enhanced load capacity and improved handling characteristics. Precision-engineered and rigorously tested to provide reliable replacement for original equipment, the 929-928 offers a professional-grade upgrade for vehicles demanding superior suspension performance under heavy loads.
