Equalizer Coupler/Hitch Grease

Equalizer High-Performance Coupler & Hitch Grease

When you invest in a precision towing system, maintaining it properly is just as important as selecting the right hitch. Equalizer — the brand behind the original 4-Point Sway Control™ weight-distribution hitch — applies that same commitment to engineering to its purpose-built coupler and hitch grease. The result is a high-performance lubricant designed specifically to keep Equal-i-zer hitch systems running smoothly, quietly, and corrosion-free mile after mile.

What Makes Equalizer Hitch Grease Different

Equal-i-zer is the only sway control hitch made in America, and for 80 years its unique 4-point sway control system has been engineered to keep families safe on the road. That deep understanding of their own hardware is exactly why Equalizer's lubricant stands apart: it is formulated with the specific friction tolerances and metal surfaces of their hitch sockets in mind, not as a generic, one-size-fits-all product.

Equal-i-zer High Performance Hitch Socket Lubricant is specially formulated to keep your hitch operating smoothly while protecting metal surfaces from rust and wear. It reduces friction for easier hitching and unhitching, minimizes noise, and helps preserve the finish on hitch balls for reliable, long-lasting performance.

Key Benefits for Your Hitch System

• Noise Reduction: Lubrication extends the life of the hitch, preventing rust and wear on the sockets, and provides easier hitching and unhitching. It also protects the finish on the hitch ball and quiets the noise coming from the hitch ball rotating inside the coupler.
• Targeted Application: Remove the spring arms and clean the hitch head socket friction surfaces, then apply a small amount of high-quality grease to the top and bottom of each socket and work it in by rotating the arms.
• Easy, Low-Mess Format: This Equal-i-zer high-performance lubricant comes in a convenient "lube in a tube" format that helps quiet the ride and reduce hitch wear, with an easy-application tube designed to make application less messy.
• Protective Barrier: The Equal-i-zer High-Performance Lubricant (part # EQ91-00-4250) is designed to reduce the noise of their weight distribution systems , while still allowing the hitch's integral sway friction to function as designed when applied only to the correct contact points.

How Often Should You Lubricate?

How often to grease will depend on how often the hitch is used for towing. For general use, Equal-i-zer recommends lubricating three times a year — in the spring, mid-summer, and fall. Staying on this schedule helps prevent metal-on-metal wear and keeps the coupler connection operating at its best across all seasons and road conditions.

Whether you tow a travel trailer, fifth wheel, or boat, keeping your coupler and hitch ball properly lubricated is a small investment that pays dividends in system longevity and a quieter, smoother ride.
