Hi Nathan, thank you for reaching out. The helper air spring kit enhances ride quality, stability, and control in heavy-duty vehicles. This kit does not increase your vehicle's maximum load capacity beyond the manufacturer's specified limits. Instead, it helps maintain proper ride height and suspension geometry when the vehicle is loaded, ensuring optimal handling and visibility. The air springs are adjustable via remote-mounted Schrader valves and air lines, allowing you to adapt to varying load conditions. If your vehicle information and fitment details match this product, you can use the link below to order while the part is in stock. https://www.carparts.com/air-spring/arnott/arnbagra150313?cpcid=Q1BHRzQ4NTB8V3JpdHRlbiBJbnRlcmFjdGlvbiBUZWFtIC0gQ1NRQXwvYWlyLXNwcmluZy9hcm5vdHQvYXJuYmFncmExNTAzMTN8MjAyNTA1Mjg= I'm happy to help. Enjoy your shopping!
