28in 200 Lbs Heavy Duty Gas Shock Strut for Trailer Cap - Pair

In this review of the 28in 200 Lbs heavy duty gas shock strut set, the bottom line is simple: these gas springs are built for heavy lids and caps that need strong, reliable lift support. The reviewer found them most useful for truck tonneau covers, trailer caps, heavy toolboxes and other applications where a 200 lb lift capacity and a long 28in extended length are required. Installation requires attention because the struts arrive extended and cannot be compressed by hand, but once fitted they deliver consistent controlled lift for demanding projects.

Key Features

• Length and capacity: The 28in extended length and 200 lb rating provide firm support for heavy lids, reducing strain on hinges and users.
• Interchange compatibility: The struts list multiple OEM interchange numbers, making it easier to match replacements for existing 100-200 style cylinders.
• Heavy duty application: Intended specifically for heavy lids and equipment, they work well for truck tonneau covers, trailer caps and heavy toolbox lids.
• Set of two: Supplied as a matched pair so lift force is balanced across both sides of a lid or cap for smoother operation.
• Safety note: Arrive in an extended state and cannot be hand-compressed, which prevents accidental collapse during handling before installation.

Who It's For

This set is aimed at DIYers, mechanics and fleet owners who need a robust replacement for heavy lift supports on trucks, trailers, snowmobile caps and large toolbox lids. It is a practical choice when the original part lists one of the documented OEM interchange numbers and the application requires a roughly 200 lb support rating.

Those with light lids, small hatches or applications under about 50 lb should look for lower-rated, easier-to-install options. Also, anyone uncomfortable fitting non-collapsible struts or unsure which model to pick should contact the seller or a technician before purchase.

Pros & Cons

Pros

• High load capacity suitable for heavy lids and caps requiring strong, consistent lift.
• Supplied as a matched set of two for balanced performance on dual-mount lids.
• Wide OEM interchange list helps identify compatible replacements for many original cylinders.
• Durable design intended for heavy duty uses such as trailer caps and toolboxes.

Cons

• Arrives fully extended and cannot be compressed by hand, so installation requires proper mounting and care.
• Only intended for heavy duty projects around 200 lb, so it is overkill for lighter lids.

Specifications
