Description: This air suspension kit is designed for 2001 - 2006 Toyota Tundra trucks. If the upper jounce bumper pad of your truck protrudes 1' below the frame, you need HP10158. All Toyota kits require at least 5'' between the tire and the frame and fit only with stock wheels and tires. Say goodbye to truck sag, sway, and bottoming out with the ALPHA HD PRO from Pacbrake! These air bags come with inch - thick corrosion - resistant end caps and 20 support wires, offering great strength and durability. The kit has a bouncy polyurethane bumper inside to prevent damage from bottoming out. It's perfect for those who want an internal bumper and enjoy a comfortable ride without air when not towing. You can choose to buy a Pacbrake air suspension kit with or without an in - bag bump stop. Adding a bump stop provides peace of mind as it prevents bottoming out due to rare air bag pressure loss, like an 'insurance policy'. Also, you can run these air bags at 0 psi when unloaded for better comfort. If you need max travel in your air bags, for example, to pick up trailers or boats or for off - roading, air bags without bump stops like the HP10126 ALPHA HD are recommended. Part Number: HP10126 - J. Features: 5,000 lbs of load - leveling capacity, 2.5 - hour install time, lifetime warranty, and can be run at 0 psi. Installation: Click Here.
