ARANA 27 in 250LB Gas Spring Struts ST270M250M10 - Heavy Lid Support

In this review of the ARANA 27 in 250LB gas spring struts the bottom line is clear: these are built for long, heavy lids where reliable lift and strong holding force matter. The reviewer found the pair best suited to truck caps, heavy trailer caps and basement doors that measure about 48 in side length and weigh between 225 and 280 lbs. Installation is straightforward for anyone comfortable with basic hand tools, and the unit force of 250 lb (1112N) per strut makes the biggest practical difference: lids open smoothly and stay put without extra props.

Key Features

• 27 in length: Extended center-to-center length of 27 in gives the reach needed for long lids and high-mount applications.
• 250 lb force per strut: The 1112N rated force provides firm support for heavy lids so they open and remain stable under load.
• 10mm end ball fitting: Common 10mm ball end fittings simplify replacement on many trailer and truck cap applications and match typical OEM mounting points.
• Compressed length 15.2 in: Compact compressed center-to-center dimension helps ensure the strut fits within limited clearance after installation.
• Sold as a pair: Two matched struts deliver balanced lift and synchronous operation for lids and caps where stability is essential.

Who It's For

The ideal buyer is someone replacing long, heavy lift supports on a snowmobile sled trailer, heavy trailer cap door, truck cap or a basement door where the lid weight falls roughly between 225 and 280 lbs. Installers who can measure lid weight or verify an OEM number will get the correct fit more consistently.

These struts are not for very light lids, seats or cabinets that need lower force; also customers who cannot confirm lid weight or mounting dimensions should seek professional measurement before purchasing to avoid a mismatched force or length.

Pros & Cons

Pros

• Provides strong, reliable lift for heavy lids with a 250 lb rated force per strut.
• 10mm end ball fittings and common center-to-center lengths make replacement straightforward in many vehicle and trailer applications.
• Generally easy to install, with many customers reporting under five minutes for typical installs.

Cons

What mounting end is used?
They use 10 mm end ball fittings which match many OEM mounts for truck caps and trailer lids.

Is installation difficult?
