20 Inch 120 Lbs Gas Strut Shocks - Heavy Duty Lid Lift Support

In this review the PAMAGOO 20 in 120 lbs gas struts are evaluated for DIYers and vehicle owners who need reliable, highcapacity lift support. The central reason to consider these props is their strong 534N/120lbs force, which makes heavy lids and covers easy to open with one hand; the review focuses on real uses like RV beds, truck bed covers and storage boxes and notes installation friendliness and included brackets. For anyone replacing weak springs or upgrading a heavy hatch, these struts offer clear, measurable lift capacity and a straightforward parts package.

Key Features

• High lift force: The 534N/120lbs rating provides plenty of power to support heavy lids so doors and covers can be lifted smoothly and held open without strain.
• Compact travel range: With an extended length of 20.04 in and compressed length of 12.13 in, the strut fits many standard openings while giving useful travel for lift and hold functions.
• Universal use scenarios: These gas springs work on RV beds, Murphy beds, truck bed covers, trailer doors and a range of DIY boxes, making them a versatile choice for home and vehicle projects.
• Complete mounting kit: The set includes two 20 in struts plus 4 Ltype brackets (2 right, 2 left) so the parts needed for a basic installation are in the box and ready to fit.
• Installation help: The manufacturer provides installation videos and online assistance, which can shorten setup time and reduce guesswork for firsttime installers.
• Postpurchase support: An 18month support window gives buyers access to customer service for troubleshooting after installation.

Who It's For

The struts are best for DIYers, RV owners and truck users who need a heavyduty lift support rated between 96 and 144 lbs; they suit front storage doors, camper shells, small cabinet lids and similar applications where a single set of strong gas springs will do the job. The robust 534N force is particularly helpful when onehanded opening or firm retention of a lid is desired.

Those who need precision mounting hardware beyond basic Ltype brackets, or who prefer softer, slower dampening for very delicate cabinets, should look elsewhere. Also, if bracket strength or custom end fittings are critical for a specific application, consider sourcing heavier brackets or professional installation to ensure longterm reliability.

Pros & Cons

Cons

• Some customers report the supplied brackets feel weaker than the struts, so bracket upgrade may be needed for very heavy or highcycle use.
• Installation instructions can be unclear to beginners, requiring reliance on videos or online guidance.
