SE280P40 28in 40lb Gas Struts Set - Replacement Lift Supports

In this review of the SE280P40 28in 40lb gas struts set, the bottom line is straightforward: these replacement lift supports are best for owners of truck bed covers, TV cabinets, travel trailers or toolboxes who need a direct, affordable swap for worn original struts. The reviewer found the pair easy to install and well matched to common bracket styles, with a clear advantage being the specified 28in extended and 16in compressed center-to-center lengths so you can confirm fit before buying. This review focuses on practical fit, force, and day-to-day use rather than marketing claims.

Key Features

• Exact length specs: The 28in extended and 16in compressed center-to-center dimensions make it straightforward to confirm compatibility with an existing strut's mounting points.
• Consistent force: Each strut is rated at 40 lb (178 N), providing predictable lift support for medium-weight lids and covers when paired correctly.
• Sold as a pair: The set includes two struts so both sides of a lid, tonneau or cabinet can be replaced at once for balanced performance.
• Broad interchange uses: These struts are suitable replacements for TV cabinets, truck bed covers, travel trailers, boat engine covers and similar hinged applications.
• Reinforced construction: The product highlights reinforced steel cylinder and durable seals aimed at longer life in typical exterior or workshop environments.
• Support window: ARANA offers 18 months of support and installation guidance if customers have questions or need help after purchase.

Who It's For

The SE280P40 set is aimed at DIYers and vehicle or RV owners who need a reliable, direct replacement for worn gas lift supports on medium-weight lids - think truck bed covers, camper shell lids, toolbox lids and some TV cabinet doors. It is particularly useful when the original strut used the same center-to-center length and ball-end style brackets, since customers report it often clicks onto common mounting hardware.

It is not the right choice for very heavy hatches or oversized lids that require greater than 40 lb of force per strut, or for applications where precise damping and slow-close action are essential; some users noted doors can slam if the force is marginal for their application. Always confirm interchange number and measure lengths before purchasing.

Pros & Cons

Pros

• Good value pair that replaces both sides at once for balanced operation.
• Clear length and force specs (28in extended, 16in compressed, 40 lb) make compatibility checks simple.
• Many customers found installation easy and compatible with existing brackets, often clicking on without modification.
• 18 months of customer support from the brand for installation or product questions.

Cons

• Some users reported the 40 lb force is marginal for heavier lids and can allow slamming in tougher applications.
• Must confirm interchange number and measure old struts carefully to avoid ordering the wrong length.

Our Verdict

The SE280P40 28in 40lb gas struts are a practical, cost-effective replacement for many truck bed covers, RV hatches and cabinet doors when the original strut used the same center-to-center lengths and ball-end mounting. They offer straightforward installation and balanced performance as a matched pair, making them a good value for routine replacement needs, though buyers with heavier lids should select a higher-force option.
