TOWCHECK FIELD GUIDE
What a weight-distribution hitch changes
A weight-distribution hitch uses spring bars to alter how hitch-applied load is distributed across tow-vehicle and trailer axles. It does not create payload or increase vehicle, axle, tire, receiver or trailer ratings.
What the terms mean
Front axle load restoration compares front-axle measurements before coupling, after coupling without distribution, and after the hitch is adjusted. The vehicle and hitch manufacturers provide the actual adjustment targets and limits.
Worked example
Common mistakes
- Treating spring bars as additional payload
- Ignoring separate receiver ratings for carrying and distributing modes
- Adjusting by vehicle appearance alone without following documentation
Frequently asked questions
Does a WDH raise tow rating?
No.
Is sway control the same thing?
No. Weight distribution and sway-control functions are related but distinct.
Can one adjustment suit every trip?
Cargo and tongue-load changes can require reevaluation under the manufacturer instructions.
