Lippert 736514 Single 4220 Acme Screw Jack Review

Does the Lippert 736514 Single 4220 Acme Screw Jack Deliver?

My quest for a robust and reliable jack solution for my truck camper setup led me to the Lippert 736514 Single 4220 Acme Screw Jack. As an equipment specialist with over a decade of putting gear through its paces in everything from dusty workshops to demanding outdoor expeditions, I approach new tools with a healthy dose of skepticism and a keen eye for detail. This particular jack promised to simplify the often-cumbersome process of leveling and securing a camper, a task that can quickly become a chore if the equipment isn’t up to snuff. The lure of a product from Lippert, a name generally associated with RV components, certainly piqued my interest.

The initial need arose from a particularly frustrating camping trip where one of my older, generic jacks proved insufficient, leading to a precarious situation that required a hasty manual adjustment. It highlighted the critical importance of dependable lifting mechanisms, especially when dealing with significant weight and the unpredictable nature of uneven terrain. I’d briefly considered a few other brands, including some off-the-shelf hardware store options, but their flimsy construction and questionable weight ratings made me pause.

Upon receiving the Lippert 4220 Acme Screw Jack, my first impression was one of solid, no-nonsense construction. The zinc-plated and powder-coated outer tube felt substantial, and the overall heft suggested it was built to handle some serious load. There was an immediate sense of relief, knowing I was likely upgrading from my previous makeshift solution.

Real-World Testing: Putting Lippert 736514 Single 4220 Acme Screw Jack to the Test

First Use Experience

My initial deployment of this jack occurred in my own garage, on a relatively level concrete surface, to get a feel for its operation before facing a less predictable campsite. The process was straightforward: I attached the jack to the designated mounting point on my truck camper, a task that involved a few bolts and a secure connection. Cranked by hand, the Lippert 736514 Single 4220 Acme Screw Jack extended smoothly, with a satisfyingly positive engagement of the Acme screw mechanism.

The 2,200-pound capacity per jack felt more than adequate for my application, and the up to 34.5″ of lift provided ample adjustment for achieving a perfectly level rig. I even subjected it to a slight wobble test by gently shifting my weight on the camper frame; the jack remained perfectly stable, instilling confidence. No binding, no excessive effort required, just a consistent, predictable lift.

Extended Use & Reliability

Over the course of several camping trips, this single screw jack has become an indispensable part of my setup. From dusty forest roads to slightly sloped gravel sites, it has performed admirably. I’ve encountered situations where the ground wasn’t perfectly firm, and the jack’s robust build seemed to handle the minor variances without complaint.

The plated and powder-coated outer tube has proven its worth, resisting the inevitable scuffs and minor impacts that come with outdoor equipment. Despite being exposed to moderate dust and occasional light moisture, there’s no visible rust or significant degradation of the finish. The inner tube also appears to be well-protected, maintaining its smooth operation. For maintenance, a quick wipe-down with a rag and a periodic application of a light lubricant to the screw threads have kept it performing like new. Compared to the budget jacks I’ve used in the past, which often developed stiffness or started to bind after only a few uses, this Lippert unit is a clear step up in terms of longevity and consistent performance.

Breaking Down the Features of Lippert 736514 Single 4220 Acme Screw Jack

Specifications

The Lippert 736514 Single 4220 Acme Screw Jack is designed as a replacement or upgrade for truck camper jack systems, specifically noted as compatible with the Happijac system. Its core specification is a 2,200-pound capacity per jack, crucial for safely supporting a significant load like a truck camper. The unit offers a substantial lift range of up to 34.5 inches, which is essential for accommodating various terrains and vehicle heights.

Construction involves a zinc-plated and powder-coated outer tube for superior corrosion resistance and protection against debris, while the inner tube boasts similar plating to prevent rusting. This combination of materials is key to its intended durability in outdoor environments. While the standard model is manually operated, the product details mention an electrical upgrade option, suggesting versatility for those seeking automated lifting. A one-year warranty is also included, providing a baseline level of assurance for the consumer.

Performance & Functionality

In its primary function of lifting and stabilizing, this jack performs exceptionally well. The Acme screw mechanism provides precise control and a stable hold, preventing any unwelcome settling or shifting. The 2,200 lb capacity feels solid; even when the camper is fully loaded and I’m moving about inside, there’s no hint of strain or instability from the jack.

The 34.5″ extension is generous, allowing for easy leveling even on uneven ground, a common challenge for RV owners. Its operation is smooth, requiring only moderate effort to crank it up or down, which is a significant improvement over less well-engineered alternatives. The most notable strength is its robust build quality, which translates directly into reliability. A potential area for improvement for some might be the manual operation, but the availability of an electrical upgrade option addresses this for those who prioritize convenience.

Design & Ergonomics

The design of this jack is purely functional, focusing on strength and durability over aesthetics, which is entirely appropriate for its intended use. The zinc-plated and powder-coated outer tube isn’t just about looks; it feels tough and resilient, suggesting it can withstand the rigors of trailering and exposure. The overall construction feels solid, with no loose parts or flimsy components that could fail under stress.

Ergonomically, the crank handle (if included with the specific model purchased, or using a standard socket wrench) provides a good grip for manual operation. The smooth threading of the Acme screw means that cranking is relatively effortless, even when under load. While there’s no complex user interface, the simplicity of its design contributes to its ease of use. The integrated mounting points appear well-engineered for secure attachment.

Durability & Maintenance

Based on my experience and the materials used, this jack is built for long-term durability. The corrosion-resistant plating and powder coating are critical for an item exposed to the elements. I haven’t observed any signs of premature wear, such as pitting on the screw, deformation of the tubes, or failure of the internal components after consistent use.

Maintenance is commendably straightforward. A quick wipe-down after exposure to dirt or moisture is usually sufficient. Periodically, I apply a light coat of grease to the Acme screw threads to ensure continued smooth operation, a standard practice for screw jacks that significantly extends their lifespan. Given its robust construction, I anticipate this jack will last many years of regular use, far outperforming lighter-duty alternatives.

Accessories and Customization Options

The Lippert 736514 Single 4220 Acme Screw Jack itself is a component, typically integrated into a larger camper jack system. As a single unit, it doesn’t come with extensive accessories, but its design is intended for seamless integration. The product description highlights an electrical upgrade option, which would involve a motor and potentially a switch, offering a significant customization for those looking to automate the lifting process.

For those who already have a system in place, this jack serves as a direct replacement part. Its compatibility with systems like Happijac is a key aspect, ensuring it can fit into existing setups. The primary “customization” here is selecting the number of jacks needed for your specific camper and potentially opting for the electric conversion if manual operation becomes too taxing.

Pros and Cons of Lippert 736514 Single 4220 Acme Screw Jack

Who Should Buy Lippert 736514 Single 4220 Acme Screw Jack?

This jack is an excellent choice for truck camper owners who prioritize robustness, reliability, and significant lifting capacity. If you frequently find yourself on uneven ground or simply want the peace of mind that comes with a well-engineered component, this unit is worth serious consideration. It’s ideal for those looking to replace worn-out or inadequate jacks on their existing Happijac system or a similar setup.

However, if you’re on an extremely tight budget and only need a jack for occasional, light-duty use, this model might be overkill. Individuals seeking an all-in-one, integrated electric jack system from the start might also find this single component approach less direct, although the upgrade option mitigates this. For best results, ensure you have the necessary mounting hardware and a compatible crank tool or socket for manual operation.

Its 2,200-pound capacity and 34.5-inch lift range are backed by a construction designed to withstand the rigors of outdoor use, evident in its corrosion-resistant plating and durable build.

Considering its solid performance and the quality of materials, the price of $706.49 for a single jack, while substantial, feels justified for the reliability and longevity it offers.
