ARANA 12.2" Gas Struts 12-inch 40 lb Lift Support — 2-Piece Replacement for Truck Tool Box, Camper Shells

These ARANA C16-11028 gas struts are 12-inch, 40 lb lift supports sold as a 2-piece replacement set for truck tool box lids, camper shell doors, and toppers.

Designed as a direct-fit replacement for several OEM numbers, the ARANA 12.2" extended (7.5" compressed) gas shocks deliver controlled lift and hold for lightweight lids and doors. Each strut uses a 10mm ball-stud socket end fitting and provides approximately 40 pounds (178 N) of force, making the set suitable for Leer, SnugTop, A.R.E., and similar caps, toppers, and toolboxes. The pair ships with two shocks and ARANA offers 365-day customer support to address fitment or part issues.

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

Fit depends on length, end fitting, and required force. Measure the installed strut from center of ball to center of ball when fully extended and compare to 12.2" extended / 7.5" compressed; confirm your mount uses 10mm ball studs. If your OEM part number matches C1611028, C16-11028, 24066-001, LGP6-120-40, 70092PK, 7009-2PK, or Weather Guard 21-0370, these ARANA struts are intended as replacements.

• Extended length: 12.2 inches; compressed: 7.5 inches

• Force: 40 lb (178 N) per shock

What kinds of lids and doors will these 40 lb gas shocks support?

These struts are engineered for lighter lids and doors where each shock provides 40 lb of lift. Typical uses include camper shell doors, truck topper windows, tool box lids, and lightweight fiberglass caps. They are not intended for heavy industrial lids or anything exceeding the recommended weight range.

• Ideal for Leer, SnugTop, A.R.E. caps and similar truck toppers
• Suitable for aluminum or light steel toolbox lids
• Recommended load per lid: roughly 32–45 pounds total
• Common applications: trunk-like lids, access panels, and lightweight cabinet lids

How do I install and maintain these ARANA gas struts?

Installation is typically straightforward when your mount points use 10mm ball studs: remove the old struts, snap the new socket ends onto the studs, and check operation. For best performance, keep pivots clean, avoid lifting beyond design angles, and do not puncture or disassemble the strut. If the ball studs differ, adapters or different mounting hardware may be necessary.

• Snap-on 10mm ball-stud sockets for quick replacement
• Verify mounting angle and clearance before final installation
• Wipe pivots periodically; avoid oil or solvent contamination
• Contact ARANA support for missing parts or fit questions
