44 in 80LB Gas Shock Struts for Tonneau Covers - Heavy Duty Support

In this review of the 44 in 80LB gas shock struts, the bottom line is straightforward: these long, heavy-duty lift supports are aimed at truck owners, RV and trailer users who need a firm, reliable hold for tonneau covers, truck toppers or hatch doors. The set of two replaces heavy OEM springs with an extended 44 in length and about 80 lb force per strut, so the single biggest reason to buy is the substantial, stable support they provide when preventing accidental closure during loading or access.

Key Features

• Extended length: The 44 in size gives reach for long tonneau covers and camper lids where shorter struts fail to engage properly.
• High lift force: Each strut is rated around 80 lb, offering firm support to keep heavy bed covers and RV doors open under load.
• Wide compatibility: Designed to work with pickup bed covers, truck toppers, RV beds, trailer hatch doors and snugtop lids for broad replacement use.
• Easy installation: The click-and-clip end fittings let most users swap old struts in minutes with just a flat screwdriver and no special tools.
• Interchange guidance: Sold as ST440M80 replacements, buyers are prompted to measure size and force or check OEM numbers to ensure correct fit.
• Aftercare promise: The seller offers 18-month order protection and 24-hour email support for installation or selection help.

Who It's For

The ideal buyer is someone fitting a long tonneau cover, snowmobile trailer hatch, RV door or truck cap that needs more lift force than standard short struts provide; contractors, outdoors enthusiasts and truck owners hauling gear will appreciate the firm hold. Installers who value fast, tool-free swapouts will also like the quick clip-and-click setup.

Those who should look elsewhere include owners of lightweight covers or lids that require low-tension supports, and anyone unable to verify the needed force and length; because these are heavy 80 lb struts, incorrect sizing can lead to poor closure behavior or premature wear.

Pros & Cons

Pros

• Strong 80 lb lift gives secure hold for heavy tonneau covers and RV doors.
• Long 44 in length suits extended lids and long-bed applications.
• Quick installation with simple clip ends makes replacement fast and tool-light.
• Seller support and 18-month protection provide added purchase confidence.

Cons
