AUCLIDIS 17-inch Gas Strut Lift Supports — Set of 2, 20 lb (89 N) Replacement for Camper Shells & Toolbox Lids

AUCLIDIS 17-inch gas strut set replaces worn lift supports on camper shells, topper caps, toolbox lids and snugtop doors, delivering reliable 20 lb (89 N) opening assistance.

If your camper shell, truck topper or toolbox lid no longer stays open or is hard to lift, these AUCLIDIS gas struts are built as direct replacements for common OEM numbers including C1615645 / C16-15645 and GSNI-5200-20. Sold as a pair with ball-socket ends and a clear specification sheet, the set is designed to match form, fit and function for many Weather Guard/related box models so you can restore safe, controlled lift and hold performance.

How do these gas struts match my original parts?

Each AUCLIDIS strut lists multiple interchange numbers so you can cross-check against the code stamped on your existing cylinder. The product provides the same ball-to-ball dimensions, ball-socket type and force rating as many OEM replacements, minimizing modification.

• Interchange codes: C1615645, C16-15645, 70952pk, GSNI-5200-20 and more.
• Ball sockets: nylon 10 mm on both shaft and body for direct fit.
• Force: 20 lb / 89 N — matches typical topper and toolbox applications.
• Sold as a set of two with an installation guide for reference.

What are the exact dimensions and mechanical specs?

Knowing the extended and compressed lengths and the connection sizes is vital for an accurate swap. These struts measure center-to-center and use standard nylon ball sockets so they work with many factory mounting studs.

• Extended length (ball center to ball center): 17.16 inches.
• Compressed length: 11.22 inches.
• Connection: 10 mm nylon ball sockets on both ends.
• Rated force: 20 lb (89 N) for smooth lift and controlled lowering.

How easy is installation and what’s included?

Installation is straightforward for anyone comfortable with simple hand tools: detach the old struts from their ball studs and clip the new sockets onto the existing studs. The package contains two struts and a concise installation guide to help you complete the swap quickly and safely.

• Package: 2x 17" gas struts and 1x installation guide.
• Mounting: snap-on nylon ball sockets fit typical OEM studs—no welding or special tools.
• Time: most replacements take 10–30 minutes per side depending on access and hardware.
• Support: AUCLIDIS offers a 12-month replacement guarantee and customer service.

Which lids, shells and models will these struts fit?

This AUCLIDIS set is engineered for many camper shell and toolbox lid models; refer to your original strut part number or the box model list to confirm compatibility. The listing includes an extensive fit list for common Weather Guard-style boxes and similar canopies.

Who is this for? These AUCLIDIS 17" 20 lb gas struts are intended for truck and camper owners, mechanics and fleet managers who need a dependable, direct-fit replacement for worn or failed lift supports on camper shells, topper caps, toolbox lids and similar access panels.
