This Ride-Rite air helper spring kit mounts between the frame and rear suspension of select Toyota Tundra trucks without factory air suspension. Inflating the springs levels the truck under heavy loads or tongue weight, reducing rear sag and restoring steering and braking feel. The no-drill kit fills manually through individual inflation valves, and an Air Command compressor can be added later.
