44Inch 40Lbs Gas Struts Pair for Tonneau Cover and Truck Bed - Heavy

In this review the reviewer looks at a pair of 44 in gas struts designed for heavy lids and covers; the bottom line is they are a practical, heavy-duty replacement for tonneau covers, truck bed hatches and large cabinet lids where a reliable 40 lb lift per strut is required. The set ships as two shocks with a 44.00 in extended length and 24.25 in compressed length, and the single biggest reason to buy is the clear specification for midweight DIY projects that need corrosion resistant construction and a known 178 N force rating.

Key Features

• Force and length: Each strut delivers 178 N (about 40 lbs) of force and extends to 44.00 in so it suits larger covers and lids that need firm support.
• Compression range: The compressed length of 24.25 in gives a wide working stroke for raising and lowering medium-weight panels smoothly.
• End fittings: The struts use 13 mm ball stud end fittings for straightforward attachment to common mounting hardware.
• Durable materials: Constructed from stainless steel with a hydraulic oil seal for improved corrosion resistance and long outdoor life.
• All-weather use: Rated for harsh conditions, including heavy rain and very low temperatures down to minus 104F, so they hold up outdoors.
• Kit contents: The package includes two gas struts, an installation guide, and a 12-month warranty for basic buyer reassurance.

Who It's For

This pair is aimed at DIYers and vehicle owners replacing or upgrading lift supports on truck tonneau covers, camper hatches, toolbox lids, floor hatches and Murphy-style bed doors. It is a good fit when each strut needs to handle roughly 80-120 lbs of lid weight in tandem and when the side length of the cover or door is more than 50 in.

It is not ideal for very light lids that require gentle assist or for installations where the end fittings are not compatible with 13 mm ball studs. Buyers unsure about fit or required force should contact the seller before purchase or consult a pro to confirm the 178 N rating matches their application.

Pros & Cons

Pros

• Clearly specified 178 N force per strut makes selection straightforward for midweight lids.
• Stainless steel construction and hydraulic seals improve corrosion resistance for outdoor use.
• Simple 13 mm ball stud fittings allow common hardware compatibility and easy installation.
• Includes installation guide and a 12-month warranty for added confidence.

Cons

• Some users report variable long-term strength; a few reviews mention loss of force over time, so longevity may vary by use case.
• They cannot be safely compressed by hand, so installation may require tools or assistance.

Our Verdict

For anyone who needs reliable lift assist for large truck bed covers, tonneau lids, camper hatches or heavy cabinet doors, this 44 in, 178 N pair is a sensible, value-oriented choice that balances force, corrosion resistance and common end fittings. It is best for projects where each strut will support roughly 80-120 lbs in tandem; those needing softer assists or expecting extreme long-term wear should consider alternatives or confirm compatibility first.
