Add adjustable load-leveling support to your hauler with the Arnott Industries Air Suspension Helper Spring Kit / Suspension Leveling Kit (MPN BAG-TTUN0721), a rear air helper spring kit for the 2007-2021 Toyota Tundra. It uses AccuAir air springs that provide load-bearing support through air pressure you can adjust for different loads, helping you safely maximize your truck's OEM-specified load capacity. See the Buyer's Guide tab for engine-specific fitment.

  • Adjustable load leveling: air springs carry load through air pressure that can be dialed in for varying weight, helping level the vehicle under load.
  • Improved ride quality: designed to enhance the ride by reducing inter-leaf friction and softening contact between the axle and the frame to reduce a bottoming-out event.
  • Steering & braking under load: helps maintain steering control and brake effectiveness through weight-shift events when the vehicle is loaded.
  • Better road visibility: leveling the vehicle under load helps keep the vehicle and its sightlines properly positioned.

Mounted at the rear, this kit adds helper air springs alongside the factory suspension to support and stabilize the truck when carrying or towing within safe load and towing capabilities. It is listed under both names — Air Suspension Helper Spring Kit and Suspension Leveling Kit.
