Hurrey's Tow & Load Support Calculator – BETA
Estimate payload, rear sag and tongue weight, then get transparent recommendations for Air Lift airbags, onboard air, SumoSprings, Timbren SES and torsion/cushion hitches. This is a sanity-check tool — not a replacement for scale tickets or OEM data.
Tow & Payload Calculator
Start with a vehicle preset, tweak weights, and we’ll estimate payload usage and sag.
Air, Helper Springs & Hitch Suggestions
Recommendations based on your load, sag and towing setup.
Onboard Air & Wireless Control
Why onboard air turns airbags into a real tow system.
Real-World Tow Notes
Keep expectations honest – and upgrades targeted.
- Tongue weight wants ~10–15% of trailer weight (bumper pull).
- 5th wheel / gooseneck often runs 15–25% pin weight.
- Airbags help leveling and stability – they do not increase GVWR or tow rating.
- Payload sticker wins every argument about “how much it can tow.”
- Air Lift = adjustable, best for changing loads.
- SumoSprings = no-air helper for constant loads.
- Timbren SES = heavy, commercial, plow, or hard-use trucks.
- Onboard air turns “yeah it works” into “this tows awesome.”
Legal & Safety Disclaimer
This tool provides generalized towing, payload and suspension support guidance. All numbers are estimates based on typical vehicles and do not replace certified scale measurements, manufacturer towing guides or printed ratings on your truck’s door sticker.
Airbags, onboard air, helper springs and Timbren SES do not increase your vehicle’s factory GVWR, GCWR, payload rating or tow rating. They improve leveling, stability, ride quality and control when used within those limits. Always verify actual weights using scales and follow OEM and hitch manufacturer instructions. Improper towing or overloading can result in loss of control, component failure, injury or worse.
