Special Features

  • [COMPLETE REAR-AXLE SOLUTION] Upgrade your F-350 with this all-in-one suspension kit. Includes 2x high-density rubber springs, heavy-duty mounting brackets, and a full hardware set (bolts & washers). Replaces everything from the frame down to the axle for a total suspension refresh.
  • [8,600 LBS LEVELING SUPPORT] Engineered to eliminate rear-end squat, trailer sway, and body roll. These helper springs provide massive load-carrying capacity, ensuring your truck remains level and stable even when hauling heavy 5th-wheel campers or gooseneck trailers.
  • [REINFORCED STEEL BRACKETS] Features industrial-grade steel brackets with a high-durability anti-corrosion coating. These precision-fit mounts replace rusty or snapped factory brackets, providing a rock-solid foundation that handles the toughest job site vibrations.
  • [PROGRESSIVE RIDE TECHNOLOGY] Our micro-cellular rubber springs offer a progressive rate—they stay soft when empty but provide more support as the load increases. Enjoy the leveling power of air bags with zero maintenance, no air lines, and zero leaks.
  • [30-MIN BOLT-ON UPGRADE] Designed as a direct-fit replacement for OEM bump stops. With the included high-tensile hardware, installation is a simple bolt-on process—no drilling required. Backed by GNXFixt's 1-year warranty and 24/7 technical support.
