HUOPO 12.2" Gas Struts for Truck Tool Box — 40 lb Support, 2-Pack, 10mm Ball

HUOPO C16-11028 are 12.2" center-to-center gas struts that deliver 40 lb support for truck tool box lids, camper shells, and similar enclosures — sold as a 2-pack.

These gas shocks replace a variety of common OEM part numbers and are designed for easy, fast installation without special tools. Built with a double-sealed piston and corrosion-resistant finish, they are intended to provide smooth lift and hold performance in outdoor conditions. Before ordering, confirm the center-to-center dimensions and ball stud diameter on your current struts to ensure compatibility.

How do I know these will fit my toolbox or camper shell?

Measure your existing strut from ball center to ball center when fully extended and compare it to the HUOPO specification. Also verify the compressed length and the 10 mm ball stud to ensure mounting points match. If your lid or door requires a heavier or lighter lift, choose a different rated strut.

• Extended length: 12.2" (center-to-center)
• Compressed length: 7.5" (center-to-center)
• Ball stud diameter: 10 mm
• Support force range: 32–45 lb (40 lb nominal)

What vehicles and parts do these gas struts replace?

These struts are compatible with many tool boxes, truck toppers, camper shells, and RV doors from popular manufacturers. They are listed as equivalents to several interchange numbers used by OEMs and aftermarket suppliers. Check the printed part code on your current strut to match replacements precisely.

• Replaces: C16-11028, 24066-001, LGP6-120-40, 70092PK, 7009-2PK

How difficult is installation and what tools do I need?

Installation is straightforward and typically takes only a few minutes with common hand tools. Most users can swap these struts in under five minutes per side by removing the old ball studs and snapping the new end fittings onto the existing mounts. HUOPO offers support if you encounter alignment or orientation questions during installation.

• Estimated install time: about 3–5 minutes per strut
• Tools: basic wrench or socket to remove ball stud nuts
• No special compressors or presses required; push-on end fittings
• Beginner-friendly instructions and customer support available

How durable are these gas shocks for outdoor use?

The struts use a rust-resistant coating and a double-layer oil-sealed piston design to help maintain reliable performance across temperature and humidity changes. That construction reduces leakage risk and keeps the rod sliding smoothly under repeated cycles. Properly matched lifting force and correct mounting orientation will extend service life.

• Double-layer oil seal for extended life and reduced leaks
• Rust-resistant exterior finish for outdoor exposure
• Rated for routine vehicle and RV access use
• 18-month quality guarantee and 24-hour support from HUOPO

If you need an easy-to-install replacement with measured fitment and weather-ready construction, this two-pack is a practical choice — just confirm the dimensions and ball stud size before buying.
