Detailed Description
Built for the Toyota Tundra rear suspension, this Arnott helper air spring kit adds adjustable support where extra payload or towing weight can change ride height and handling. The air springs reduce inner-leaf friction, which helps the suspension move more smoothly under load while supporting steering control and braking effectiveness during weight shift events. Arnott BAG-TTUN0721 is a practical choice for drivers who need rear-end support without changing the vehicle’s core suspension layout.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Rear sag when carrying cargo or towing
- Reduced stability from uneven load distribution
- Bottoming out over bumps or dips
- Suspension harshness caused by added weight
- Loss of braking control during weight transfer
Installation Notes and Tips
Install at the rear suspension location specified for the 2007-2021 Toyota Tundra. Verify in-bed hitch clearance before installation and confirm all air spring connections are sealed before pressurizing the system. BAG-TTUN0721 includes mounting hardware; bushings, front shocks, front sway bar, rear coil springs, rear shocks, rear sway bar, reservoir, and springs are not included.
Quality Assurance
Arnott supplies suspension components engineered for load support and ride control applications. BAG-TTUN0721 uses regular-grade rubber bellows and an 8-stud mounting design for the listed Tundra rear fitment.
