Air Lift Air Spring Kit for Toyota Sienna (2004–2020) — 60732 Internal 1,000 lb Load-Leveling, 5–35 PSI

Air Lift 1000 Air Spring Kit (60732) is an internal coil-spring air helper that restores ride height and provides up to 1,000 lb of load-leveling capacity for 2004–2020 Toyota Sienna models.

This compact, bolt-in kit installs inside your Sienna's existing coil springs to prevent sagging, reduce bottoming out and keep the vehicle level when carrying heavy loads or towing. Designed for durability and simple service, the Air Lift 1000 uses pressurized cylinders and an accessible air line so you can add or release air with common compressors or portable inflators. Backed by a limited lifetime warranty to the original retail purchaser, the kit is a cost-effective way to improve handling and ride quality without replacing the factory suspension.

How does the Air Lift 1000 stop my Sienna from sagging under load?

The Air Lift 1000 installs inside the coil spring and acts as a supplemental air cylinder, supporting the existing suspension as load increases. As pressure is added, the cylinder takes up additional weight, restoring the vehicle to its normal ride height and reducing rear-end droop.

• Provides up to 1,000 pounds of additional leveling capacity
• Adjustable air pressure range: 5–35 PSI for fine tuning
• Fits inside factory springs—no major suspension surgery required
• Simple inflation through an accessible air line with common compressors

Will installation change driving handling or increase wear?

When installed correctly, the 1000 Series works with your stock suspension to reduce sway, nose-dive, and bottoming without significantly altering normal ride characteristics. It supports the load rather than replacing the coil, so steering and alignment geometry remain intact when air pressure is set appropriately.

• Internal fit keeps factory ride quality when unloaded
• Reduces body roll and rear squat under load for safer handling
• No permanent modification to springs or frame required for most installs
• Durable materials and high burst-strength design to withstand regular use

How do I inflate and control the air springs?

Inflation is performed through the kit’s included air line, which accepts any standard inflator capable of delivering the required pressure. You can use portable compressors, onboard air systems, or even compact pump tools to adjust PSI depending on load and desired firmness.

• Air pressure range: 5–35 PSI for ride tuning
• Compatible with portable pumps, onboard compressors, and standard air tools
• Quick inflation/deflation to match varying cargo or passenger loads
• Easy-access routing for convenient pressure checks and adjustments

What warranty and support come with the kit?

Air Lift provides a Limited Lifetime Warranty to the original retail purchaser for catalog-listed applications used under normal operating conditions. The warranty protects against manufacturing defects, while a 60-day ride satisfaction guarantee allows you to confirm the kit meets your expectations.

• Limited Lifetime Warranty to the original purchaser for covered applications
• 60-day Ride Satisfaction Guarantee
• Warranty exclusions include racing, off-road/commercial misuse, or improper installation
