Euplokeer 20" Gas Shock Struts 40 lb (Pair) – 19.69" Extended 11.8" Compressed RV & Trailer Lift Supports

Euplokeer 20-inch gas shock struts (40 lb / 178 N) are replacement lift supports designed to open and hold RV doors, cargo bays, camper shells, and hatches safely and smoothly.

These two 20" gas struts from Euplokeer provide a direct-replacement option for a wide range of recreational vehicle and trailer applications where a 40-pound lift is required. Each cylinder extends to 19.69 inches and compresses to 11.8 inches, fitting common OEM interchange numbers. They come ready for quick installation using standard 10mm ball-mount brackets and basic hand tools.

How will these gas struts fit my RV or trailer?

Match three things before purchasing: the pound-force rating, the OEM interchange number, and the extended/compressed lengths. Euplokeer lists multiple cross-reference numbers so you can check compatibility with your existing struts.

• Extended length: 19.69 inches; compressed: 11.8 inches.
• Pound rating: 40 lb / 178 N to support many medium-weight panels.
• Compatible cross-reference: C16-08316, GSNI-5300-40, SX200P-40, ML34-40 and others.
• Requires 10mm ball-style mounting brackets (sold separately).

What installations are these gas shocks suitable for?

These struts are built for a variety of lift applications where a moderate holding force is needed. They work well on RV compartment doors, camper shells, boat hatches, trailer lids, and lightweight bed platforms.

• RV and motorhome cargo bay doors and storage compartments.
• Trailer and topper camper shell lift supports.
• Boat hatches, shed windows, and wooden box lids when matched to weight.
• Food truck service windows or other fold-out panels with correct brackets.

How do I choose and install the right replacement?

Start by measuring your existing strut fully extended and compressed, and note the OEM number stamped on the cylinder if present. Compare those values with Euplokeer’s specifications and replace ball-mount hardware as needed for a secure fit.

• Measure extended length and compressed length of old strut for a match.
• Confirm 40 lb / 178 N is sufficient for the panel weight and swing angle.
• Use 10mm ball mount brackets — search the referenced ASIN or local supplier.
• Install or remove clips with a flat-head screwdriver; no specialized tools required.
