Product Description

The FOX 803-04-046 is a Heavy Duty rear coil spring kit for the 2021-2026 Ford Bronco 2-Door. This pair of upgraded rear springs increases the Bronco's static load capacity by up to 500 lbs over the rear axle, maintaining proper ride height after adding heavy accessories like bumpers, spare tires, roof racks, and armor. The springs provide 2.5" to 3.5" of rear lift and deliver a 22% higher spring rate compared to standard FOX production springs, preventing sag under heavy loads while preserving ride quality on and off road.

Constructed from high tensile chrome silicon steel, each spring is e-coated and finished with a durable silver powder coat for long-lasting corrosion resistance. Designed to work seamlessly with FOX Performance Elite and Factory Race Series rear coilover kits, meeting the same rigorous durability standards as all FOX production springs. Coilover shocks are not included and must be purchased separately. Also available in black finish as FOX 803-04-047. Sold as a pair -- includes two rear springs for a complete rear axle upgrade. Estimated installation time is approximately 3 hours.
