Dorman 929-930 Severe Heavy Duty Coil Spring Set Increased Load Capacity - Rear 70%

The Dorman 929-930 Severe Heavy Duty Coil Spring Set is engineered to deliver exceptional load-handling performance for vehicles subjected to continuous heavy hauling conditions. This rear coil spring upgrade provides a substantial 70% increase in load handling capability over the vehicle's nominal spring rate, making it an ideal solution for pickup trucks, SUVs, RVs, plow trucks, and commercial vans that regularly carry heavy loads.

Key Features:

• 70% increased load handling capacity over stock spring rate for superior heavy-duty performance
• Precision-engineered design improves ride quality, reduces driver fatigue, and enhances handling characteristics
• Quality steel construction with powder coat finish ensures reliable performance and corrosion resistance
• Variable rate spring design with 0.71-inch wire diameter for optimal load distribution
• Pigtail over center end configuration for secure mounting
• Maintains stock ride height while significantly increasing load capacity
• Sold as a pair for complete rear axle upgrade

Custom-designed to replace worn or damaged original coil springs while providing dramatically improved load handling over stock replacements. Note that severe heavy-duty springs provide a stiffer ride than stock springs. For applications requiring less stiffness, consider Dorman's 35% increased load capacity alternative spring sets.
