6 Best Trailer Jack Covers For Long Term Storage

The trailer jack is the workhorse of any mobile dwelling, yet it is often the first component to succumb to rust and electrical failure when left exposed. Neglecting this critical pivot point during off-season storage invites moisture intrusion that can seize gears and degrade sensitive electronic motors. Investing in a quality cover is a low-cost insurance policy against the headache of a non-functional lift when the next adventure begins.

Classic Accessories Vinyl Cover: Best Overall

This cover strikes the ideal balance between durability and ease of use, making it the standard choice for most standard A-frame trailers. It features a water-resistant vinyl construction that sheds rain and snow effectively while preventing the UV damage that often cracks plastic components. The drawstring hem ensures a snug fit that prevents wind from billowing the fabric during transit or long-term storage.

For the average owner who needs reliable, year-round protection without overthinking the technical specs, this is the go-to solution. It is straightforward, effective, and built to withstand the typical wear and tear of outdoor storage. Choose this cover if a balance of price and performance is the priority.

Explore land 600D Cover: For Harsh Weather

When a trailer is parked in environments characterized by heavy snowfall, intense desert sun, or coastal humidity, standard vinyl often fails. The Explore Land 600D cover utilizes heavy-duty polyester fabric that is significantly more puncture-resistant than lighter alternatives. The 600-denier rating refers to the density of the weave, ensuring that the cover won’t tear under the weight of accumulated ice or heavy winds.

This is the recommended choice for those living in extreme climates where environmental stressors are constant. While it requires slightly more care during installation due to the weight of the fabric, the trade-off in longevity is significant. If the goal is “set it and forget it” protection, this heavy-duty option is worth the extra investment.

Camco Vinyl Jack Cover: Best Budget Pick

The Camco vinyl cover is a testament to the fact that basic protection does not have to be expensive. It serves its primary purpose—keeping direct water and dust out of the jack’s housing—without unnecessary bells and whistles. Its minimalist design makes it incredibly easy to slip on and off, which is a major advantage for those who frequently move their rig.

While it lacks the heavy-duty reinforcement of premium models, it is perfectly adequate for covered storage or milder climates. It is the perfect stop-gap or primary solution for owners on a strict budget. If the jack only needs minimal protection against light debris and occasional rain, there is no reason to look beyond this option.

Andersen Rapid Jack Cover: Top for Security

The Andersen system is unique because it focuses on a specific design footprint meant to accommodate specialized leveling equipment. This cover is engineered with a tighter profile to prevent flapping and to keep the mechanisms underneath clean and ready for immediate operation. Its design is more focused on the functional integrity of the jack’s specific mechanical path.

Opt for this if the trailer setup utilizes Andersen-specific leveling hardware, as generic covers often interfere with the fit. It is built for those who prioritize equipment precision and want a cover that respects the engineering of the lift mechanism. This is the choice for the organized owner who values a tidy, cohesive setup.

Husky Towing Superbrute: For Power Jacks

Power jacks carry sophisticated internal wiring and motor components that are notoriously sensitive to moisture ingress. The Husky Towing Superbrute cover is tailored specifically to provide a contoured fit over these larger, bulkier electrical housings. Its specialized shape prevents water from pooling on top of the motor head, which is where most electrical failures originate.

If a trailer is equipped with a high-end power jack, using a generic cover is a mistake that could cost hundreds in repairs. This cover is essential to keep the internal electrical connections dry and free of corrosion. It is the only sensible investment for protecting the motor-driven lift systems that define modern convenience.

Lippert Electric Jack Cover: Premium Pick

Lippert components are ubiquitous in the industry, and their dedicated cover reflects a deep understanding of their specific product line. This premium option utilizes high-grade, breathable materials that prevent the “greenhouse effect” common with cheaper vinyl. By allowing moisture to escape while keeping rain out, it protects both the finish of the metal and the integrity of the internal electronics.

This cover is designed for owners who have invested heavily in their gear and intend to protect that investment for the long haul. It fits with a level of precision that cheaper alternatives simply cannot match. If the budget allows for it, this is the gold standard for protecting an electric jack system.

How to Measure Your Jack for a Perfect Fit

Measurement begins with two primary numbers: the height of the jack housing and the diameter of the head. Use a flexible measuring tape to determine the circumference of the motor head if the jack is electric, as this will dictate how wide the cover opening needs to be. For manual jacks, measure from the base of the handle to the mounting plate to ensure the cover won’t be too short.

Always account for an extra two inches of clearance to ensure the cover can be pulled taut without straining the seams. Avoid guessing based on the model year of the trailer, as jacks are frequently replaced or upgraded by previous owners. A loose cover will flap in the wind and accelerate wear, while a cover that is too tight will be impossible to secure effectively.

Choosing the Right Material for Your Climate

Material selection is the most significant factor in how long a cover will last. Vinyl is excellent for shedding water, but it can become brittle and crack in freezing temperatures if it is not UV-treated. Conversely, heavy-duty polyester or canvas blends breathe better, which is crucial in humid climates to prevent mold and mildew growth underneath the cover.

In coastal areas, look for fabric treated with a salt-resistant coating to prevent corrosion of the aluminum or steel housing. If the trailer stays in a high-sun environment, prioritize covers with high UV-resistance ratings to prevent the material from bleaching and disintegrating. Assessing the primary climate threat—whether it is moisture, wind, or heat—should dictate the material choice.

Prepping Your Jack for Long-Term Storage

Never place a cover over a dirty jack, as grit and grime act like sandpaper during high winds. Start by cleaning the jack housing with a mild detergent and, if it is a manual model, apply a thin layer of waterproof grease to the exposed screw threads. This keeps the internal mechanism lubricated and ready for use after months of inactivity.

Inspect the electrical wires for any frayed insulation before securing the cover. If the jack is electric, a small packet of silica gel placed inside the cover can help absorb lingering moisture, acting as a secondary line of defense. This preparation transforms a simple cover into a comprehensive storage strategy.

Jack Cover Mistakes That Lead to Damage

The most common mistake is failing to secure the cover tightly, which creates a “sail” effect that puts unnecessary stress on the jack head. If the cover is not secured at the bottom with a drawstring or strap, high winds will eventually tear the fabric or vibrate the jack’s internal components. Additionally, using a cover that is not breathable can trap moisture, essentially creating a corrosive environment inside the housing.

Avoid the temptation to use a garbage bag or tarp as a makeshift solution. These items trap condensation against the metal, accelerating rust and electrical rot rather than preventing it. A purpose-built, breathable, and properly secured cover is the only way to ensure the jack remains in pristine working order.

Protecting a trailer jack is a small task that pays dividends in reliability and resale value. By matching the right material and fit to the specific environment, you ensure that the equipment remains operational regardless of how long the unit sits idle. A well-covered jack is a reliable starting point for every future trip.
