ARANA C16-15645 are 17.13" center-to-center gas struts rated 20 lb (89 N) each, sold as a 2-piece set for lifting and supporting truck toppers, camper shells, RV/storage doors, and toolbox lids.

These replacement lift supports from ARANA match OEM number C16-15645 (C1615645) and provide a straightforward swap for worn or weak struts on Leer toppers, ARE caps, motorhome storage doors, camper shells, and toolbox lids. Each strut compresses to 10.83" center-to-center and extends to 17.13", delivering 20 lb (89 N) of force per unit. The pair is supplied ready to install — no special tools required — and comes with ARANA’s 365-day support for questions or installation help.

How do I know these struts will fit my topper or lid?

Confirm fit by comparing both the OEM part number and the center-to-center lengths. ARANA’s C16-15645 is a direct-replacement option when your existing struts list OEM C16-15645 or C1615645 and match the compressed/extended measurements.

• Extended length (center-to-center): 17.13"
• Compressed length (center-to-center): 10.83"
• Force per strut: 20 lb (89 N)
• Sold as a 2-piece set — replace both sides for balanced operation

What tools and steps are needed to install ARANA gas struts?

Installation is typically simple and can be completed with basic hand tools. You won’t need to pre-compress the struts; they should be attached in their natural state and secured to the existing ball studs or brackets on the lid and frame.

• Common tools: wrench or socket set and a flathead screwdriver for retaining clips
• Attach upper socket to ball stud, then secure lower socket to base stud
• Install both struts to maintain even lift force and alignment
• Do not manually compress the strut before installing

How will these struts improve daily use of a toolbox or camper shell?

Replacing weak or leaking struts restores the smooth, controlled opening and holding of lids and doors. With 20 lb of force per strut, ARANA supports medium-weight lids and prevents sudden closures while loading or accessing gear.

• Provides consistent lift and hold for safer hands-free access
• Reduces wear on hinge hardware by sharing load
• Designed for applications like truck caps, camper shells, RV doors, and toolboxes
• Sold as matched pair for balanced operation

What should I check before buying or returning these gas springs?

Verify the OEM number, measure center-to-center lengths on your old struts, and confirm the required force rating. If your lid has unique brackets or nonstandard ball studs, note those mounting details before ordering.

• Match OEM numbers: C16-15645 or C1615645
• Confirm compressed 10.83" and extended 17.13" center-to-center dimensions
• Check that 20 lb (89 N) per strut meets your lid’s weight
• Contact ARANA support for installation guidance or compatibility questions
