Dukuge 20" Gas Struts 100 lb Set of 2 — 19.69" Extended, Dust Covers for Tanning Beds & RV Beds

These Dukuge 20-inch gas struts deliver 100 lb lift force per cylinder to lift, hold and gently lower heavy lids on tanning beds, RV beds, toolboxes and other large panels.

If you need reliable, heavy-duty support for a lid or hatch that weighs roughly 80–110 pounds, this pair of gas springs provides a direct OEM-style replacement and a straightforward option for DIY conversions. Each strut features a 19.69" extended length and an 11.82" compressed length measured hole-to-hole, steel hardware, dust covers for longer life, and ball-stud connectors for quick installation.

How will these gas struts change the way I open and close heavy lids?

Installed correctly, the Dukuge struts make lifting a heavy panel nearly effortless and keep it steady in the open position so you can work hands-free. The gas-charged cylinders cushion the closing motion to prevent slamming and reduce wear on hinges.

• Smooth assisted lifting for lids in the 80–110 lb range
• Controlled, dampened closing to protect frames and finishes
• Hold-open stability so the lid remains secure while in use
• Dust covers to reduce contamination and extend service life

Will these fit my tanning bed, RV bed, or toolbox?

The Dukuge kit is made to match several common OEM part numbers and suits applications where a 100 lb gas lift is required. You’ll want to confirm the extended and compressed lengths and ball-stud dimensions against your current strut or bracket layout before buying.

• Check extended length: 19.69" (hole-to-hole)
• Check compressed length: 11.82" (hole-to-hole)
• Connector sizes: 10 mm ball-stud hole, 8 mm thread and ball diameter
• Compatible with lids requiring ~80–110 lb of lift assistance

How easy is installation for replacement or DIY projects?

There are two common installation paths: a direct bolt-on replacement when your existing struts match the specs, or a DIY retrofit where you choose bracket locations and fasteners. The package includes ball studs and mounting nuts, plus a simple guide, but additional brackets or hardware may be needed depending on your application.

• Replacement: swap the old strut using the included ball studs and hardware
• DIY retrofit: mark mounting points, install brackets (not always included), attach strut
• Works with standard 8 mm threaded fittings and 10 mm ball-stud holes
• Installation tools and some mounting brackets may be required separately

What are the key specifications I should note before ordering?

Knowing the main measurements and force rating helps you choose the correct strut for safe, reliable operation. These Dukuge cylinders are supplied as a matched pair with hardware designed to fit many OEM configurations.

• Force rating: 100 lb (≈445 N) — suitable for lids ~80–110 lb
• Extended length: 19.69 inches; compressed length: 11.82 inches
• Connector hole diameter: 10 mm; thread and ball diameters: 8 mm
• Supplied items: 2x gas struts, 4x 10 mm ball studs with spacers, 4x 8 mm nuts, instruction sheet

Who is this for? If you own a tanning bed, RV bed platform, heavy toolbox lid, trunk-style storage box or a DIY hatch that needs dependable lift assistance, this Dukuge pair gives a heavy-duty, OEM-compatible solution. It’s also a good choice for hobbyists and technicians who prefer a bolt-on replacement or a sturdy gas-spring upgrade that reduces manual lifting, prevents slamming, and keeps lids safely open while in use.
