SuperSprings Helper Spring Kit | 1500 lb Capacity, F-150 & Silverado/Sierra 1500

SuperSprings is a patented, self-adjusting suspension system that works alongside the factory leaf springs to level a sagging rear end and add load capacity - no manual air pressure to set, no compressor, and nothing to maintain once it's installed. It engages automatically as load increases, so there's no adjusting before every trip.

• Adds up to 1,500 lb of load support in tandem with factory leaf springs
• Self-adjusting - engages automatically under load, no manual tuning
• Reduces body roll and sway by up to 30%
• Maintenance-free: no airlines, compressors, or leaks
• Made from SAE 5160H high-grade steel, shot peened to relieve stress and extend life
• Typical installation takes about one hour

Fits 2014-2025 Silverado/Sierra 1500 and 2014-2025 F-150, excluding Raptor models and mono-leaf suspension.
