EQUALIZER High Performance Trailer & Hitch Lubricant — 4 oz bottle, long-lasting low‑friction film

EQUALIZER 91-00-4250 High Performance Lubricant is a concentrated 4-ounce formula designed to reduce friction and protect moving trailer and hitch components under heavy use.

This compact, high-performance lubricant is formulated for metal-to-metal contact on towing hardware, hinges, bearings and other small but critical parts. Packaged in a 4-ounce container, it fits in toolboxes and glove compartments for on-the-road touch-ups. The non-greasy, long-lasting film helps resist moisture, dirt and wear so moving parts keep working smoothly without frequent reapplication.

How will this lubricant improve towing and trailer hardware performance?

It minimizes metal-to-metal friction where parts pivot, slide or rotate, so components move freely and with less resistance. That smoother motion reduces noise, wear and the risk of binding during hookup or while towing.

• Creates a low-friction barrier on couplers, latches and hinges
• Reduces squeaks and sticking in frequently used parts
• Helps extend service intervals for small assemblies

Is the 4-ounce size practical for field and workshop use?

Yes — the 4 oz bottle is intentionally portable for roadside repairs and routine maintenance while still holding enough product for multiple applications. Its compact size makes it simple to store with towing accessories and carry on trips.

• Fits in toolboxes, glove compartments and storage bins
• Ideal for quick re-lubrication during stops or at campgrounds
• Small volume reduces waste while covering key touch points

What surfaces and parts are best treated with this lubricant?

This lubricant is intended for typical trailer and hitch metal components: couplers, pivot pins, locks, slides and similar moving hardware. It’s formulated to adhere to metal surfaces and keep working in conditions where moisture and dirt are present.

• Trailer couplers and latch mechanisms
• Pivot points, hinges and shackles
• Small bearings, slides and threaded fittings

How should I apply and maintain treated components?

Apply a small amount to a clean, dry surface and move the part to distribute the lubricant into contact areas. Reapply after heavy use or if you notice increased noise or stiffness; wipe off excess to avoid attracting grit.

• Clean dirt and old residue before applying
• Use sparingly; a thin film is usually sufficient
• Check treated points during routine inspections and after wet conditions

Who is this for? EQUALIZER 91-00-4250 is aimed at trailer owners, RV and towing enthusiasts, fleet operators and maintenance technicians who need a reliable, portable lubricant for small but important hardware. If you want to reduce noise, prevent binding and keep couplers, hinges and pivots operating smoothly between service intervals, this compact high-performance lubricant is a practical addition to your toolbox or roadside kit.
