The Sea Sense Trailer Ball 1 7/8"x2" is a solid steel hitch ball built to handle the demands of boat trailer towing. Whether you're launching a fishing rig or moving a weekend cruiser, a properly sized trailer ball is critical infrastructure—it's what actually connects your boat to your vehicle, so it has to be tough and reliable. This ball couples with standard hitches and is engineered to match your trailer's pull configuration.
Construction matters in a marine environment. This trailer ball is chrome plated to resist corrosion from salt spray, road salt, and moisture—the usual enemies of anything metal near water. The ball itself is solid steel, precision machined for consistency and strength, and comes with a grade 8 nut and lock washer to ensure a secure, vibration-resistant connection once installed. A 1" sleeve is included to help adapt the ball to your specific hitch setup.
Trailer ball sizing is straightforward but non-negotiable: this unit is sized at 1 7/8" diameter with a 2" shank length, a standard specification that works with many common boat trailer hitches. Before purchase, verify your trailer's ball socket diameter and your hitch's pull-height requirements to confirm this ball is the right fit for your setup. A mismatch here creates a safety problem, not just an inconvenience.

Frequently Asked Questions
What size ball do I need for my boat trailer?
Trailer balls come in a few standard sizes. This ball is 1 7/8" in diameter—check your trailer's hitch socket to confirm it matches. The socket size is usually stamped or cast into the coupler itself. If you're unsure, measure the inside diameter of the coupler or consult your trailer's documentation.
Will this trailer ball work in a saltwater environment?
Yes. The chrome plating is designed to resist corrosion from salt spray and moisture. That said, rinsing and occasional maintenance extend the life of any metal hitch hardware, especially in harsh marine conditions.
What hardware is included?
The ball ships with a grade 8 nut, a lock washer, and a 1" sleeve. The grade 8 fastener is stronger and more corrosion-resistant than standard hardware, and the lock washer reduces vibration and loosening during use. The sleeve aids in fitting the ball to your hitch shank.
What is the shank length on this ball?
The shank length is 2", which is the distance from the base of the ball to the threaded hole where the nut fastens. This measurement matters for proper fit and load distribution on your hitch.
