ST360P30 36in 30lb Gas Struts Pair - Heavy Duty Lift Support

In this review of the ST360P30 gas struts, the bottom line is simple: these are practical, heavy duty lift supports intended for DIYers who need reliable opening assistance for lids and covers up to roughly 36 in side length. The reviewer found the pair offers a consistent 30 lb force per strut and a long 36 in extended length, making them useful for tonneau covers, toolbox lids, camper kitchen doors and similar applications. Expect solid materials and weather resistance, and be aware the struts cannot be compressed by hand during installation.

Key Features

• 36 in extended length: Provides a long reach suitable for doors and covers where each side length is over 36 in, reducing the need for extra linkage.
• 133 N / 30 lb force per strut: Designed to support about 30 lb per unit so two struts share heavier lids and maintain controlled opening.
• Durable stainless construction: The stainless steel body and hydraulic oil seal deliver corrosion resistance for outdoor use and rough weather.
• Temperature tolerant: Built to operate in harsh conditions, including heavy rain exposure and temperatures down toward minus 104F.
• Installation kit and guide included: Comes with two struts, fitting hardware and an installation guide to simplify DIY fitting for common applications.
• Backed by warranty and support: Includes a 36-month warranty and 24 hour customer service for peace of mind after purchase.

Who It's For

The ST360P30 pair is best for vehicle and workshop DIYers who need sturdy lift supports for truck toolboxes, tonneau covers, toy box lids, camper kitchen doors, floor hatch storage and similar lids where the side length exceeds 36 in. It suits users replacing worn struts with a unit that emphasizes corrosion resistance and a controlled opening.

It is not the first choice for someone who needs adjustable or much higher force ratings, or for projects with confined mounting that require compressing the strut by hand during fitting. If you cannot confirm fit or force needs, contact support before purchasing.
