28 Inch Gas Struts Shock 350LB Lift Support Pair - Heavy Duty Lid

In this review the 28 in gas struts shock 350LB pair is judged as a heavy duty solution for lids and hatches that need consistent lifting power. It is aimed at owners of RV beds, toolboxes and trailer hatches who need a strong, weatherproof lift support for lids weighing roughly 335-365 lb. The single biggest reason to buy is the high 350LB/1557N force per strut and full 28 in extended length, which delivers predictable opening and holding for large lids that would otherwise be hard to manage.

Key Features

• Force 350LB/1557N: Provides reliable lift for heavy lids and keeps them supported while open without sudden drops.
• 28 in extended length: Offers long reach and leverage for lids with side lengths in the 42-56 in range, making installation positions flexible.
• Durable brackets: Comes with L-type mounts and bracket hole sizes specified for secure attachment to boat covers, toolboxes and floor hatches.
• Weather resistance: Built to withstand outdoor conditions, including heavy rain and very low temperatures down to minus 104F.
• Complete kit: Ships as a pair with four L-type mounts and an installation guide, so users receive all basic hardware needed for common installs.
• Wide application range: Suitable for RV queen beds, truck canopy covers, camper shells and other DIY uses where heavy-duty lift support is required.

Who It's For

This product is best for RV owners, trailer builders and tradespeople who need a heavy-duty gas spring pair to support large lids, storage beds and hatches. It suits applications where a lift pair must handle roughly 335-365 lb total and where a long 28 in extended length is required for proper geometry.

It is less suitable for very small lids, lightweight cabinetry or installs that require fine-tuned soft-close action; those users should look for lower-force struts or dedicated soft-close units. Also note that some installers may want heavier mounting hardware than supplied if the installation sees extreme leverage.

Pros & Cons

Pros

• High 350LB lift force gives dependable support for heavy lids and prevents slamming.
• Long 28 in extended length covers many large lid geometries and offers good opening angle.
• Built for harsh weather and low temperatures, suitable for outdoor and marine use.
• Package includes two struts, four L-type mounts and a guide for a complete basic install.

Cons

• Some customers report mixed hardware quality and occasional bracket bending on first use, so stronger aftermarket mounts may be wise.
• Instructions are basic and may not suit first-time installers needing step-by-step diagrams.

Specifications

Our Verdict

The 28 in 350LB gas strut pair is a practical, heavy-duty lift support for RV beds, toolboxes and large hatches where brute strength and weather resistance matter. It offers solid value when matched to lids in the 42-56 in range and for weights around 335-365 lb, though installers should inspect supplied brackets and be prepared to upgrade mounting hardware in high-leverage applications.
