Dukuge 20" Gas Struts 100 lb Set of 2 — 19.69" Extended RV & Tanning Bed Lift Supports, Includes Mounting Hardware

Dukuge 20-inch 100 lb gas struts are a matched pair of heavy-duty lift supports designed to lift, hold, and lower lids and hatches weighing about 80–110 lb with smooth, controlled motion.

These gas springs replace common OEM numbers (C1608054, ML34-100, 6939 and equivalents) and come as a ready-to-install set for RV beds, tanning bed lids, toolbox covers, storage hatches and other heavy panels. Each strut measures 19.69 inches extended and 11.82 inches compressed (hole-to-hole), delivers roughly 100 lb (445 N) of force, and includes dust covers and mounting hardware to simplify installation. The kit is engineered for steady support, gentle closing, and reliable holding under load.

How do these gas struts fit my RV bed or tanning bed lid?

The Dukuge struts are designed to match several OEM part numbers and common dimensions so they can often replace original units directly. Check hole-to-hole extension (19.69 in) and compressed length (11.82 in) plus connector sizes to confirm compatibility.

• OEM cross-references: C1608054, ML34-100, 6939, 6939S10.
• Extension length: 19.69 inch; compression: 11.82 inch (hole-to-hole).
• Force: ~100 lb (445 N) suitable for lids 80–110 lb.
• Connector specs: ball stud Ø10mm hole, thread Ø8mm, ball stud Ø8mm.

What happens to lid movement after installation?

Once installed, the struts provide controlled lift assistance and hold the lid open firmly so it does not slam shut. Closing is gradual and cushioned, reducing wear on hinges and preventing sudden drops.

• Effortless lifting of heavy panels with reduced manual force.
• Steady load holding keeps lids open at any angle within range.
• Gentle, secure shutting protects contents and hardware.

Can I install these gas springs myself or use them as direct replacements?

You can install Dukuge gas struts in two ways: a simple bolt-on swap for direct replacements, or a DIY install using brackets positioned to meet the specified lengths and force requirements. The set includes ball studs, nuts, spacers and an instruction guide; additional brackets are sold separately if needed.

• Replacement: remove old strut and bolt the Dukuge unit in the same position.
• DIY install: choose mounting points, attach brackets, then fasten struts.
• Package includes: 2 gas struts, 4 ball studs with spacers, 4 bore nuts, and guide.

What technical details should I check before ordering?

Confirm the required lift force, stroke length and connector sizes against your lid or hatch specifications. Incorrect force or wrong mounting geometry can affect operation, so compare the strut’s measurements and ball stud dimensions with your application.

• Force rating: 100 lb (445 N) — suitable for lids ~80–110 lb.
• Stroke and lengths: 19.69" extended, 11.82" compressed (hole-to-hole).
• Connector sizes: 10mm ball stud hole, 8mm thread, 8mm ball stud diameter.
• Includes dust cover to extend working life in dusty environments.

Who is this for? Dukuge 20-inch 100 lb gas struts are aimed at DIYers, RV owners, tanning salon equipment technicians, and anyone replacing worn lift supports on heavy lids and hatches. If you need a direct-fit replacement for common OEM numbers or a robust pair of struts for a custom build that must support roughly 80–110 lb, this set supplies matched force, mounting hardware, and a simple installation path.
