C16-08055 20 inch 120lb/534N Gas Strut Shock Spring Lift

AUCLIDIS C16-08055 gas struts are a pair of 20-inch, 120 lb (534 N) lift supports designed to replace worn or broken shocks on RV bed storage, truck tonneau covers, Leer toppers and similar lids.

These replacement lift supports deliver a direct-fit alternative for common OEM part numbers and are engineered for everyday convenience when opening and holding lids, mattresses and access panels. Each set contains two matched gas struts with 10 mm nylon ball sockets at both ends, an installation guide, and AUCLIDIS customer support with a 12-month replacement guarantee.

How do these gas struts work on RV beds and truck tonneau covers?

The C16-08055 struts use compressed nitrogen and an internal piston to provide consistent force when extending and holding a lid open. They replace factory units to restore smooth lift, controlled descent and secure support without manual propping.

• 20 inch extended length (ball center to ball center): 19.69 in
• Compressed length (ball center to ball center): 12.20 in
• Rated force: 120 lb / 534 N per strut
• Ball sockets: nylon 10 mm at both ends for common mounting hardware

Will these fit my existing OEM part number or camper topper?

AUCLIDIS lists common interchange references so you can match replacements by the original stamp on your strut. If your current gas strut carries any listed part number, these should be a compatible, like-for-like option.

• Interchange numbers noted: 021155, 78327, C1608055, TAG 78327, 78327-120, m34-110, ML34-120, se200p-120
• Confirm fit by comparing extended/compressed lengths and 10 mm ball socket dimensions
• Contact AUCLIDIS support if uncertain about fit before installation

What should I expect during installation and routine use?

Installation is straightforward for anyone familiar with ball-end gas struts: remove the old unit from its ball mounts and snap the new nylon sockets onto the factory balls. Routine care is minimal — avoid forcing or overloading the lid, and inspect mounting points periodically for corrosion or loosened hardware.

• Package includes two gas struts and an installation guide
• Snap-on 10 mm nylon ball sockets require standard ball-stud mounts
• Check mounting studs, brackets and fasteners for wear before assembly

How durable are these struts and what warranty is provided?

These gas lift supports are built for repeated use on vehicle and furniture lids; however, longevity depends on load, environment and correct installation. AUCLIDIS backs the product with a 12-month replacement guarantee and customer service to help with any issues.

• Constructed to deliver consistent 120 lb lifting force per strut
• Suitable for indoor/outdoor use when mounted correctly
• 12-month replacement guarantee and AUCLIDIS support available
