SL2790 28 in 90lb Gas Struts Set - Strong Lift Support

In this review of the SL2790 28 in 90lb gas struts set, the bottom line is simple: these are replacement lift supports built for applications that need a firm, reliable lift such as RV bed boxes, tonneau covers and truck bed covers. The reviewer found the two-piece set delivers a clear benefit when a higher lift force is needed, combining a long 28 in extended length with 90 lb (400 N) force per strut for confident opening and holding. Installation was straightforward and the pair offers a sensible value for users who verify interchange numbers and length before buying.

Key Features

• Length and fit: 28 in extended and 16 in compressed center-to-center lengths provide a predictable fit for applications matching those dimensions.
• High lift force: 90 lb (400 N) per strut supplies strong support for heavy lids and covers so openings feel controlled and secure.
• Two-piece set: Sold as a pair so both sides of a lid or cover can be replaced together for even lifting and better balance.
• Interchange compatibility: Multiple interchange numbers are listed to help users confirm compatibility with existing OEM parts before purchase.
• Application range: Designed for RV bed boxes, storage lids, tonneau and truck bed covers and similar closures where a high-force prop is required.
• Support policy: 18 months of support from the brand provides help with installation or product questions.

Who It's For

The SL2790 set is best for vehicle and trailer owners who need a strong, straightforward replacement lift support for heavy lids and covers, including truck bed covers and RV storage boxes. It is also suitable for DIY installers who can measure center-to-center length and compare interchange numbers to ensure a correct fit.

It is less suitable for users who have lighter lids that require lower lift force, or for anyone unwilling to verify dimensions and interchange numbers; those users should choose a lower-force or shorter strut instead.

Pros & Cons

Pros

• Strong 90 lb force gives confident opening and steady hold for heavy lids.
• Sold as a matched pair so both sides can be replaced at once for balanced lift.
• Clear length specs and many interchange numbers make replacement fitment easier to confirm.

Cons

• Some users report variable long-term durability, so longevity may differ by use case.
• Must confirm interchange number and length before purchase to avoid incorrect fit.
