Vepagoo ST440M100 44 in 100LB Gas Lift Struts - Heavy Duty Support

In this review the Vepagoo ST440M100 44 in gas lift struts are assessed for heavy-duty use on truck beds, trailer lifts and RV hatches. The bottom line: these long 44 in, 100lb-per-strut units are designed for anyone who needs firm, extended support for heavy covers and doors, and they stand out for their straightforward, clip-style installation and solid holding force. They are best chosen when matching length and force to your original part, since the physical size and 100lb force are the core reasons to buy.

Key Features

• Extended length: The 44 in length provides reach for larger truck bed covers, trailer ramps and rooftop tents where shorter struts will not fit.
• Strong 100lb force: Each strut delivers 100lb (445N) of lift, offering firm support to prevent accidental closure on heavy doors and covers.
• Broad compatibility: Marketed for snowmobile trailer lifts, RV doors, trap doors and tonneau covers, these are suitable for many heavy-duty applications when the size and force match.
• Quick install: The click-and-clip ends allow a swap-out with just a flat screwdriver in most installs, so replacement takes minutes without specialty tools.
• Stable support: Designed to hold heavy truck bed covers and hatches steady to reduce the risk of collapse during loading and unloading.
• Aftercare: The seller offers 24-hour email support and 18-month order protection for help with selection and installation.

Who It's For

This product is for owners of trucks, trailers and RVs who need a long, high-force replacement gas spring for heavy lids and covers. Installers replacing worn or broken hydraulic arms on tonneau covers, snowmobile trailer lifts or roof hatches will appreciate the 44 in reach and the 100lb lift that provides reliable, steady support.

Those who should look elsewhere include people who need a different force rating or a shorter length, and anyone who is unwilling to measure their OEM size and force before ordering. Also note some users reported mixed durability experiences, so if you need a custom OEM match or extreme-duty cycling beyond normal use, consider OEM-specified alternatives.

Pros & Cons

Pros

• Strong lifting force and long stroke make it effective for heavy covers and truck beds.
• Easy click-and-clip installation that typically requires only a flat screwdriver.

• Responsive customer support and 18-month order protection included.

Cons

• Durability is mixed according to customer reports, with some units failing early under heavy use.
• Must match exact length and force to existing OEM parts; wrong sizing will impair fit and function.
