ARANA 32 in 150LB Gas Struts ST320M150 - Heavy Lid Lift Support

Our review of the ARANA 32 in 150LB gas struts shows they are a straightforward replacement for long, heavy lids that need reliable lift assist. Designed as a direct replacement for OEM number ST320M150, this pair delivers a strong 667N/150LB push per strut and a long extended length, making them best for tonneau covers, truck bed covers, RV kitchen doors and other heavy lids. The single biggest reason to buy is the combination of a precise 32.00 in center-to-center extended length and a high force rating that handles lids in the 120-165lb range, when measured to the stated fit guidelines.

Key Features

• Direct replacement: Compatible with OEM number ST320M150 so buyers can match original parts and expect correct fit when measurements align.
• Precise dimensions: The extended length is 32.00 in and compressed length is 17.91 in, which helps ensure the correct stroke and geometry for long lids.
• High force output: Each strut supplies 667N/150LB of force, suitable for heavy lids that require significant lift assistance.
• Ball stud fitment: The struts fit standard 10mm ball studs, simplifying installation on common mounting points.
• Multi-scenario use: Suited for RV doors, tonneau covers, pickup bed covers and DIY builds where long struts and high force are required.
• Support policy: The brand offers installation help and an 18 month replacement support window for fit or defect issues.

Who It's For

The ARANA 32 in 150LB gas struts are aimed at vehicle owners and DIYers who need long, heavy-duty lift support for lids weighing between about 120 and 165lb and with a side length near 48 in. They make sense as a replacement for SNUGTOP-style tonneau covers or similar heavy lids when the OEM number or measured center-to-center dimensions match.

People with lighter lids, nonstandard mounting hardware, or who cannot confirm lid weight or OEM number should look elsewhere for lower-force or adjustable options. Also, if tool-free removal and very soft damping are priorities, a different, lower-force strut might be a better match.
