The R4Tech system replaces the rear steel leaf springs with a hybrid air-over-leaf setup. By adding an Air Spring in conjunction with lower-rated leaf springs, the unloaded ride is greatly improved. The air springs' adjustability keeps the vehicle capable of the same load capacity at GVW. The R4Tech allows most of the advantages of a full air suspension to be realized without requiring significant modifications to the truck. The kit fits into the existing leaf spring hangars and is all Bolt-On. The patented lower link and J-Spring stop axle windup and reduce brake hop/axle shudder under heavy loaded acceleration.

    R4Tech Features
  • Smoother, Softer Ride Loaded or Empty.
  • Greatly Improves Ride Quality.
  • Improves Roll Control and Cornering.
  • Automatic Leveling.
  • Kneeling Feature to drop the rear for loading or trailer attachment.
