Features to know about

Keeps Your Rig Level and Under Control: Trunnion Bar Weight Distribution System

When your trailer’s tongue weight throws your setup off balance, this system helps spread that weight evenly across your tow vehicle and trailer. The Lock N Roll trunnion bar design brings back a level, steady ride with smoother handling and reduced bounce. It’s rated for up to 11,000 lbs gross towing weight and 1,100 lbs tongue weight, giving you solid stability for heavier loads without the sway or sag.

No-Drill Setup That’s Straightforward to Install: Clamp-On Frame Brackets

You don’t need to drill into your trailer frame to mount this system. The no-drill, clamp-on brackets attach directly and tighten down securely. That means no counting washers or messing with extra hardware—just use the pre-installed bolt in the hitch head to fine-tune your spring bar angle. It’s a clean, simple setup that saves time and keeps your trailer frame intact.

Smooth, Quiet Operation Without Lift Chains: Rigid Bar and Bracket Design

Traditional chain-style setups can rattle and shift when you’re towing or backing up. This one uses steel bars and tensioning brackets that hold the trailer steady without lift chains. The result is a quiet, solid connection that eliminates unwanted movement and helps your trailer track true behind you.

Built Strong for Demanding Loads: Heavy-Duty Steel Construction

Every component—from the weight distribution head to the spring bars—is built from durable steel engineered to handle real towing stress. The system itself weighs 85 lbs and includes the spring bars, head, tensioning brackets, and all necessary hardware. With this kind of strength, you can count on consistent performance mile after mile.

Works Seamlessly with Lock N Roll Couplers: Designed for a Complete System

This setup is made to work with Lock N Roll articulating couplers and a 3" wide adjustable channel mount (sold separately). That pairing keeps things compatible and ensures the hitch geometry stays correct for reliable articulation and balanced load transfer.
