Aaiov RV Awning Gas Struts 28.74in (28") Pair — 150 lb Lift, Direct-Replace with Star Washers

These Aaiov gas struts are a paired replacement designed to restore smooth extension and retraction to 28" RV awnings, providing 150 lb (660 N) lift capacity with a 28.74" extended length.

If your camper or motorhome awning no longer opens or closes reliably, worn gas springs are a common cause. Aaiov engineered these replacement lift springs to match common OEM dimensions and mounting points so they swap in without modification. Each set is quality-checked before shipping and includes star washers to help secure pins and reduce play at the attachment points.

Will these struts fit my Dometic or other OEM awning?

They are intended as direct replacements for multiple OEM part numbers and many Dometic-compatible awning arms. Match the key measurements and OEM references to confirm fit before ordering.

• Extended length: 28.74 inches (read against your current strut).
• Compressed length: 16.05 inches (important for clearance when closed).
• Attach pin diameter: 3/8 inch — ensure your mount accepts this size.
• Referenced OEM numbers: #3108392.139, #3310555.010, PM3990, 68475, 80985, 025214, 69-3723.

How much force do these lift springs provide and why it matters?

Each gas spring delivers about 660 N (150 lb) of force, chosen to handle mid-weight awning lids and maintain stable operation. That rating helps the awning extend smoothly and resist sagging while parked.

• 150 lb (660 N) nominal force suited for awning lids roughly 125–166 lb.
• Stable extend/retract action to prevent sudden closures or difficulty opening.
• Designed to balance manual and power awning arms with corresponding load ranges.

Is installation difficult and what hardware is included?

Installation is straightforward for anyone comfortable replacing small struts: these are designed as direct replacements and attach with common pin-style connectors. The package includes star washers to improve locking and reduce movement at the mount points.

• Direct-replacement sizing to fit existing pin mounts without cutting or adapters.
• Includes 8 star washers to secure connections and minimize loosening.
• Typical install requires basic hand tools and a second person for safety on large awnings.

How long can I expect these replacement struts to last?

Aaiov manufactures these gas springs for extended service life and inspects them before shipment. Actual longevity depends on use, exposure to the elements, and correct installation, but the product is backed by an 18-month warranty for manufacturing defects.

• Pre-delivery testing performed to verify function and seal integrity.
• 18-month warranty covering manufacturing faults; regular maintenance recommended.
• UV exposure and salt air can accelerate wear — lubricate pivot points and inspect annually.

Who this is for: Motorhome and RV owners who need a reliable, OEM-dimensioned replacement for worn awning gas springs will benefit most. Choose these Aaiov struts if you require a 28.74" extended length, 3/8" pin fitment, and roughly 150 lb lift per strut for Dometic-compatible or similarly spec'd awnings. If your awning’s part numbers or physical measurements match the references above, this set is intended to restore consistent opening and secure support for both manual and powered systems.
