Hatchlift Cooler Strut Kit: Best All-in-One Kit

The Hatchlift kit stands out because it removes the guesswork typically associated with custom hardware installations. This system arrives as a complete package, including the gas springs, mounting brackets, and the essential ball studs required for a secure fit on most standard rotomolded coolers. It is the gold standard for anyone who prefers a turnkey solution over sourcing individual components.

For those who want to finish the project in a single afternoon without running to the hardware store, this is the clear winner. The inclusion of clear, model-specific instructions significantly lowers the barrier to entry, making it highly approachable for those without a workshop full of specialty tools. If reliability and ease of installation are the top priorities, the Hatchlift is the only logical choice.

Suspa C16 Gas Spring: Best OEM Replacement

Suspa is a powerhouse in the industrial gas spring market, and the C16 series represents the benchmark for quality and longevity. These are the components often found inside high-end RV cabinetry and factory-installed cooler systems, meaning they offer true industrial-grade performance. When durability in fluctuating temperatures is non-negotiable, these struts provide consistent resistance without leaking or fading over time.

These are best suited for the DIY enthusiast who already has brackets installed and simply needs a high-quality replacement for a worn-out unit. Because they lack the mounting hardware included in comprehensive kits, they aren’t for the absolute beginner, but they are the perfect choice for the maintainer who values proven, long-term durability. Stick with Suspa if the goal is to set the hardware and forget about it for the next decade.

Apexstone 40lb Gas Struts: Best Budget Pick

For many, the cost of specialized marine hardware can be a deterrent, but the Apexstone 40lb struts provide an excellent, functional alternative. These units are remarkably affordable and provide just enough lift force to hold a standard cooler lid open without the overkill of heavy-duty industrial pistons. They offer a smooth, predictable motion that feels far more expensive than the price tag suggests.

These are the ideal choice for smaller, portable coolers or lightweight hatch doors in a tiny home where heavy-duty force isn’t required. While they may not feature the corrosion-resistant coatings of high-end marine gear, they are more than capable for indoor use or protected outdoor storage. If the goal is to optimize a cooler on a tight budget, these will get the job done reliably.

T-H Marine Lid-N-Locker: Best for Marine Use

Saltwater environments are notoriously harsh on metal hardware, and the T-H Marine Lid-N-Locker is specifically engineered to survive those conditions. Featuring high-grade stainless steel components and superior seals, this system resists the pitting and corrosion that often seize up standard struts in mere months. It is specifically designed to handle the constant vibration and exposure common on boats and coastal living setups.

This product is an absolute necessity for anyone living on a boat or a property near the coast where moisture and salt air are constant. Choosing a standard strut here would be a mistake, as the failure rate in marine environments is extremely high for non-marine rated parts. If the cooler lives anywhere near a marine environment, the investment in T-H Marine hardware is worth every penny for the peace of mind alone.

Arana 67lb Heavy Duty Struts: For Large Coolers

Large, heavy-duty coolers—especially those packed with gear or insulation—require a higher force rating to prevent the lid from crashing down unexpectedly. The Arana 67lb struts provide the substantial lift needed to manage these hefty lids with minimal physical effort. Their robust construction ensures that they can handle the constant stress of supporting significant weight without bending or failing.

These are the clear choice for oversized coolers, storage chests, or heavy-duty benches that double as cold storage. Using a weaker strut on a large, heavy lid will result in premature failure and frustration as the piston struggles to hold the load. If the lid has significant heft, bypass the smaller, lighter-duty options and go straight for these to ensure safe and steady operation.

Camco Gas Prop Kit: Easiest to Find in Stores

Camco has built a reputation for accessibility in the RV and camping supply market, and their gas prop kit is no exception. These are readily available at almost any major camping retailer or big-box hardware store, making them the most convenient option if a strut fails while on the road. They offer a standardized performance that works well for a wide variety of lightweight applications.

While they might not boast the extreme durability of industrial-grade marine parts, they are perfectly adequate for standard cooler configurations. For the traveler who prefers picking up supplies at a local shop rather than waiting on shipping, this is the most practical route. Their simplicity makes them an excellent entry point for those attempting their first upgrade on a cooler lid.

How to Choose the Right Strut Force & Length

Calculating the correct force is the most common point of failure for beginners. You must weigh the cooler lid and measure the distance from the pivot point to the desired mounting location. As a general rule, the force (measured in pounds) should be slightly less than the weight of the lid to ensure it stays closed when you want it to, but enough to hold it steady when open.

Measure twice and mock up the installation with painters tape before drilling holes. You need to account for the “extended” and “compressed” lengths of the strut to ensure the lid can open fully without the strut bottoming out or stopping the lid from reaching its maximum angle. If the math feels overwhelming, lean toward a slightly lower force rating, as you can always add a second, smaller strut later if the lid remains too heavy.

Installing Your Cooler Struts: A Step-by-Step Guide

Start by positioning the mounting brackets with the lid in the fully open position. Use a straight edge to ensure the struts will be aligned and won’t bind during the opening or closing cycle. Mark the pilot holes carefully with a center punch to prevent your drill bit from wandering on the smooth surface of the cooler plastic.

Always use stainless steel screws and pre-drill the holes to avoid cracking the cooler walls. Once the brackets are secured, snap the ball studs into place and attach the gas struts. Check the alignment by slowly closing the lid; if you feel significant resistance or hear a grinding sound, stop and adjust the bracket position immediately to prevent damage to the strut seals.

Safety Tips for Handling Pressurized Struts

Gas struts are essentially miniature cannons filled with high-pressure nitrogen gas. Never attempt to disassemble a strut or pierce the metal casing, as the sudden release of pressure can cause severe injury. Always handle them with care, and keep them away from open flames or high heat sources that could cause the internal pressure to spike dangerously.

When installing, ensure the strut is oriented according to the manufacturer’s recommendations, usually with the piston rod facing downward. This helps lubricate the internal seals and keeps the mechanism operating smoothly. If you ever notice oil leaking from the rod or the strut failing to hold pressure, remove it immediately; it has reached the end of its service life and cannot be repaired.

Troubleshooting Common Cooler Strut Problems

If the lid pops open too quickly or struggles to stay closed, the force rating of your struts is likely too high. Conversely, if the lid crashes shut, the force rating is too low or the struts are worn out. Check that all mounting screws are tight, as loose hardware causes the strut to shift and lose its mechanical advantage during the lifting process.

Stiff or noisy operation is usually a sign that the struts are misaligned or the hinges are binding. Before assuming the struts are broken, spray a small amount of silicone lubricant on the pivot points and the rod itself. If the issue persists, check for debris caught in the ball-and-socket joints, which can prevent the mechanism from pivoting through its full range of motion.

Upgrading to a gas strut system is one of the most effective ways to refine a small-living space, turning a clunky piece of gear into a precision-engineered tool. By selecting the right kit for your cooler’s size and environment, you replace frustration with effortless function. Focus on the math, prioritize quality hardware, and enjoy the added convenience on every trip.
