ARANA 24-inch 40 lb Gas Struts for RV Door — 2-Pack Replacement Pair, 24.4"/13.7" C-C, Ball-Stud Mount

ARANA 24-inch 40lb gas struts are a two-piece replacement set designed to lift and hold RV doors, camper hatches, tonneau covers, and similar panels with a rated 40-pound force per strut.

These ARANA SE244P40S10 / SE24OTHER40 gas springs provide 24.4" extended and 13.7" compressed center-to-center lengths and deliver 40 lbs (178 N) of force each. Sold as a pair, they are built for marine, RV, and trailer applications where controlled lifting and secure support are needed. Before ordering, check the interchange number on your old struts and verify measured lengths to ensure compatibility.

Will these struts fit my RV side door or camper hatch?

They often replace common 24-inch assemblies used on side doors, rear windows, and small hatches. Fit depends on the original strut's interchange number and center-to-center measurements, so matching those details is critical for correct operation.

• Interchange numbers: SE244P40S10, SE24OTHER40 — confirm your part number
• Extended length: 24.4" (620 mm) center-to-center
• Compressed length: 13.7" (348 mm) center-to-center
• Force per strut: 40 lbs (178 N); sold as a pair — not a single unit

How much weight can these gas shocks support for DIY projects?

ARANA recommends these 40 lb struts for panels and doors that weigh roughly 30–44 pounds when used in typical single-strut configurations. If your application uses two struts, the combined support increases, but consider hinge friction and mounting geometry when estimating required force.

• Suitable single-strut support range: ~30–44 lbs
• For heavier doors, use two struts or higher-force models
• Account for hinge friction and leverage for accurate force needs
• After installation, struts compress only when mounted correctly

What should I check before buying these replacement gas springs?

Measure the center-to-center lengths of your current struts both extended and compressed, and verify the interchange number stamped on the old part. Also confirm the mounting style and ball-stud sizes so the replacement will attach and operate without modification.

• Compare interchange numbers: SE244P40S10 or SE24OTHER40
• Confirm extended 24.4" and compressed 13.7" lengths
• Verify ball-stud mount type and orientation
• Buy in pairs when your application requires two matched struts

How do these gas struts behave after installation?

Once correctly mounted, the cylinders provide smooth lift assist and stable hold in the extended position; they are designed to compress only when the door or panel is moved while installed. Installation torque and correct ball-stud seating are important for long life and consistent performance.

• Operate smoothly after proper installation and alignment
• Will compress only when mounted and the panel is moved
• Match mounting hardware to prevent premature wear
• Sold as two struts — ensures balanced lift when pairs are used
