20 inch 150 lb Gas Strut Shocks for Heavy Lids - Strong Lift Support

In this review the 20 in 150 lb gas strut pair is presented as a practical, heavy-duty option for homeowners and RV owners who need reliable lift support. The single biggest reason to buy is straightforward: these gas props offer a high lift force of 668N (about 150 lb) per strut, allowing heavy lids and doors to be opened and held with one hand after installation. The set arrives with L-type mounting brackets and an installation guide, and the seller provides online videos and 24-hour support to help with fitment and mounting.

Key Features

• High lift force: Each strut delivers 668N (150 lb) of force, providing plenty of support for lids and doors that weigh between 120 and 165 lb so they lift smoothly and stay open.
• Common dimensions: The gas props measure 20.04 in extended and 12.13 in compressed, which makes them a straightforward replacement for many medium to heavy lid applications.
• Complete mounting kit: The package includes two right and two left L-type brackets plus an installation guide so hardware for basic installations is included.
• Wide compatibility: Designed as universal 20 in struts, they are suitable for RV beds, truck bed covers, toolboxes, Murphy beds, trailer doors, and DIY projects like toy boxes or outdoor service windows.
• Installation support: The brand supplies online videos and 24-hour selection and installation assistance to reduce guesswork during fitment.

Who It's For

These gas struts are best for people who need high-capacity lift support for heavy lids and doors: RV owners replacing bed lift supports, DIYers fitting toolbox lids, and anyone working on heavy cabinet or floor doors roughly in the 120-165 lb range. The high force rating is particularly useful when one-handed opening and reliable hold-open behavior are needed.

Those who should look elsewhere include users with very light lids under 50 lb, where the force will feel excessive, and anyone who requires custom-length struts beyond the stated 20.04 in extended or 12.13 in compressed measurements. Also, customers wanting premium heavy-gauge brackets may prefer separately sourced mounting hardware.

Pros & Cons

• Clear fitment guidance and 24-hour online support reduce installation uncertainty.

Cons
