HUOPO 12" Gas Struts 24 lb Lift, 2-Pack for Truck Tool Box & Camper Shells — 10mm Ball Stud, 8.26"-12.2" travel

HUOPO C16-03795 12-inch gas struts are a pair of 24 lb lift supports designed to replace worn or broken shocks on truck tool box lids, camper shell windows, toppers and similar hinged panels.

These two gas struts come as a matching set engineered to restore smooth, controlled opening and holding power for lids and rear windows that use a 10mm ball stud fitting. They fit many common OEM numbers (C16-03795, C16-09903, C16-25685 and equivalents) and are built to a compact compressed length with a longer extended reach to suit medium-duty applications on trucks, RVs and DIY projects.

How will these gas struts fit my truck tool box or camper shell?

Measure your original strut center-to-center lengths when compressed and extended and check the OEM number stamped on the old part. The HUOPO pair has a compressed center-to-center length of about 8.26" and an extended length of about 12.2", with 10mm nylon socket connectors and 10mm ball stud end fittings for direct swap where those fittings match.

• Compressed length: ~8.26" center-to-center
• Extended length: ~12.2" center-to-center
• Connector: 10mm nylon socket; end fitting: 10mm ball stud
• Cross-references: C16-03795, C1603795, C16-09903, C1609903, C16-25685, C1625685

How simple is the installation and what hardware do I need?

Installation is straightforward and typically takes under five minutes per strut if your existing ball studs are compatible. No drilling is required when replacing like-for-like—remove the old sockets with a flat-head screwdriver and press the new nylon sockets onto the ball studs. If your vehicle lacks compatible mounting studs, separate mounting brackets (sold separately) will be needed.

• Replace using a flat-head screwdriver—no drilling for like-for-like swaps
• Mounting brackets not included; purchase separately if required
• Package includes two gas struts; brackets or fasteners may be needed
• Ensure vehicle ball stud size matches the 10mm fitting

What kinds of applications and weight capacity are these struts suitable for?

Each strut is rated for approximately 24 pounds of lift force, making the pair suitable for many medium-duty lids and windows such as weather guard tool boxes, camper shell rear windows, toppers, canopies and lightweight RV doors. They are best used where controlled lift and hold-open force is required rather than heavy industrial lids.

• Lift force: ~24 lb per strut (pair provides balanced support)
• Common uses: truck caps, tool box lids, camper shells, RV windows
• Also useful for DIY cabinetry and access panels needing medium lift
• Not intended for very heavy or oversized industrial lids

Who is this for: These HUOPO C16-03795 gas struts are made for truck owners, RVers and DIY mechanics who need a reliable replacement for worn lift supports on tool box lids, camper shells and similar hinged panels. If you have an existing 10mm ball stud setup and need a quick, like-for-like swap to restore smooth opening and secure hold-open action, this two-pack provides an affordable, easy-to-install option with 18 months of after-sales support if you need help identifying fitment or completing installation.
