Weight Distribution Hitch Explained
A weight distribution (WD) hitch uses spring bars to lever some tongue weight forward onto the truck's front axle and back onto the trailer axles, leveling the rig and restoring steering grip.
When you need one
Many truck manufacturers require WD above a certain trailer or tongue weight. Check your owner's manual. Many travel trailers over ~5,000 lb are towed with WD.
What it does not do
- It does not increase payload or towing capacity.
- The hitch itself (often 60–120 lb) adds to payload.
Setting it up
A common target is restoring the front axle to roughly 50–100% of its unhitched weight (check your truck maker's guidance). Confirm with a CAT scale weigh, bars on and off.
Sway control
Many WD hitches include friction or cam sway control. Proper tongue weight (10–15%) is still the first defense against sway.

Safety note: These are planning estimates, not a guarantee your setup is safe or legal. Always verify with your truck's door-jamb sticker, the manufacturer's towing guide for your exact configuration, the trailer's VIN sticker, and a real weigh at a CAT scale. Never exceed any rating.
