Firestone Coil-Rite Rear Air Helper Spring Kit (4155) for Select 2004-2022 Toyota Sienna and GM Vans
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2004-2022 Toyota Sienna, Scion xA, Chevrolet Uplander, Buick Terraza, and Saturn Relay.
The Firestone Coil-Rite Rear Air Helper Spring Kit (4155) is engineered to provide a variable spring rate for vehicles with coil spring suspensions. These durable polyurethane air springs install directly inside your existing rear coil springs, allowing you to level your vehicle and improve handling when hauling heavy loads or towing. By adjusting the air pressure, you can compensate for varying weights to maintain a level ride, which ensures effective braking, steering, and proper headlight aim.
- Load Support: Supports between 500-1,000 lbs per set (not to exceed vehicle GVWR).
- Adjustable Performance: Variable spring rate can be tuned by inflating or deflating the air springs like a tire.
- Durable Construction: Made of high-strength, elastic polyurethane for long-term stability and comfort.
- Temperature Rated: Operating range from -40°F (-40°C) up to 180°F (82°C).
- Stability Improvement: Reduces bottoming out, improves balance, and helps prevent uneven tire wear.
- Manufacturer Part Number: 4155
