Description
The Lock N Roll Adjustable Height Trailer Hitch is a vehicle-side hitch designed to work with Lock N Roll trailer-side couplers to create a strong, fully articulating towing connection. This design helps reduce shock loads and allows your trailer to move naturally over uneven terrain, making it well-suited for both highway towing and off-road use.
The PN 503 features a 2-7/8″ wide, four-hole channel that bolts directly into a standard 3″ wide adjustable height channel, allowing you to fine-tune hitch height for proper trailer alignment. Precision-drilled mounting holes support industry-standard 2″ hole spacing for 5/8″ bolts, simplifying installation with commonly available hardware.
Built from high-strength alloy steel, the hitch incorporates a solid 1″ diameter bearing and grease port to support smooth articulation and long service life. When paired with a compatible Lock N Roll coupler, the system allows full multi-axis articulation and 360° rotation, helping absorb bumps and road shock that can stress traditional ball couplers.
Rated for 11,000 lbs gross trailer weight and 1,100 lbs tongue weight, meets SAE J684 towing safety standards, and is tested by independent labs for reliability and durability.
Note: This is a vehicle-side component only and must be used with a compatible Lock N Roll vehicle-side channel bracket and trailer-side coupler (sold separately).
