ARANA 20-inch Gas Struts 2-Pack 100 lb Each — Heavy-Duty RV & Camper Tonneau Lift Supports

ARANA C1608054 are 20-inch gas lift struts sold as a 2-piece set, each rated at 100 lb (445N) and designed to support lids or covers weighing roughly 85–110 pounds when used as a pair.

These gas springs provide controlled lifting and holding for heavy lids, hatches and covers on campers, tonneau boxes, RV beds and storage compartments. They replace common part numbers such as 6939, 6939S10 and C16-08054 and come in a standard 20-inch dimension (500 mm extended, 300 mm compressed). The set does not include mounting brackets, so confirm your bracket type or purchase compatible hardware separately.

How do I know these struts will fit my lid?

Fit depends on two things: the physical length of the strut in both extended and compressed positions, and the load your lid places on the shocks. Measure the existing strut lengths or the lid geometry, and calculate the combined load the two struts must support.

• Extended length: 19.7 inches (500 mm)
• Compressed length: 11.8 inches (300 mm)
• Force per strut: 100 lb (445 N)
• Best used as a pair to support lids weighing about 85–110 lb

What applications are these 20" gas springs suited for?

These lift supports are engineered for heavy-duty, vertical or near-vertical lids and doors where strong, smooth support is needed. They are commonly used on camper shells, RV beds, tonneau covers, storage boxes, floor hatches and other heavy custom lids.

• RV and travel trailer bed supports
• Tonneau covers and truck storage lids
• Basement or floor hatches, large cabinet doors
• Heavy custom-build lids and compartment doors

Do these gas struts come with mounting brackets or installation hardware?

The C1608054 pair ships without mounting brackets or fasteners. If your application requires ball-stud brackets or specific end fittings, plan to reuse the originals or order compatible hardware separately to ensure a secure installation.

• Package includes: two gas struts (no brackets)
• Compatible interchange numbers: 6939, 6939S10, C1608054
• If brackets are needed, purchase separate mounting kits
• Follow vehicle or lid manufacturer guidelines for placement

How long will these gas shocks last and what support is offered?

Longevity depends on usage, environment and correct sizing. ARANA provides 18 months of product support for installation guidance or replacement assistance—reach out via the seller contact if you have questions before or after purchase.

• Rated 100 lb (445 N) per strut for robust lifting
• Designed for heavy-duty, frequent use when properly matched
• 18 months support/service included with purchase
• Do not use on lids under ~80 lb; risk of over-damping

Who is this for: The ARANA C1608054 20" gas prop pair is intended for DIYers, RV owners, truck and camper repair shops, and anyone replacing worn or underpowered shocks on heavy lids and covers. Choose this set if your lid geometry matches the 19.7" extended and 11.8" compressed lengths, you need roughly 100 lb of force per strut, and you can supply or source the required mounting brackets. If you’re unsure about correct sizing, measure your current struts or the lid weight and contact ARANA for assistance before ordering.
