5 Best Weight Distribution Hitch For Boat Trailer With Surge Brakes in 2026: A Practical RV Guide
Weight distribution hitch options for a boat trailer with surge brakes: three Andersen chain hitches and two Equal-i-zer kits, with a note on surge use.
By Hardcastle's RV Editors
10 min read5 products evaluated
Surge brakes use forward movement of the trailer against the tow vehicle to apply the brakes, and the forward force of many weight distribution systems can engage the actuator. No listing here states that it is compatible with surge brakes, so none is called surge-compatible.
The five picks are three Andersen chain hitches and two Equal-i-zer four-point kits. Before buying, ask the hitch maker and the trailer maker whether the system is rated for surge brakes.

What Matters Before You Choose a Weight Distribution Hitch For Boat Trailer With Surge Brakes
Key buying criteria so you get the right fit the first time.
Surge brake compatibility
The forward leverage of some weight distribution systems can engage a surge actuator, so only systems rated for surge brakes should be used. None of these listings states such a rating. Ask the maker in writing.
Add-on friction bars
Add-on friction sway bars can interfere with surge actuators and may void a surge rating, per general advice. The Equal-i-zer kits integrate sway control, and the Andersen hitches use chains. Confirm each with the maker.
Tongue weight on a boat trailer
A loaded boat trailer's tongue weight changes as fuel and gear change. Weigh it loaded and compare it with the stated rating. Equal-i-zer lists 600 and 1,000 lb.
Frame and bracket fit
Many weight distribution hitches need frame brackets, and boat trailers may have little room. Check the bracket location against the trailer frame. A kit that does not fit is useless.
Drop and receiver size
Andersen states 6 inch and 8 inch drops on 2 inch shanks and an 8 inch drop on a 2.5 inch shank. Match to your truck and trailer. Measure ball height with the trailer level.
