ARANA C16-08055 20″ 120 lb Gas Struts
This ARANA option provides 120 lb (535 N) of lift at 20 inches extended length. It’s positioned for heavy-duty applications like RV beds and tonneau covers where lid weight sits around 105–135 lbs. Interchange references include C16-0805 and C1608055. The listing warns to verify compatibility by comparing part numbers against your current struts, as compatibility can vary with different tonneau cover models and mounting brackets.
Euplokeer ST270P-80 27in Gas Strut
Euplokeer’s pair features 80 lb (356 N) of lift with a 27-inch extended length and 15.4-inch compressed length. They are marketed as direct replacements for certain SL26-80 and ML26-80 configurations, covering stages where the tonneau lid or undercover bed uses these precise part numbers. The listing highlights the kits include two shocks plus mounting hardware, emphasizing easy installation and compatibility with a range of tonneau covers and undercover top assemblies.
Vepagoo ml2860 28in Gas Struts
The Vepagoo ml2860 set provides a robust 200 lb (889 N) per-strut force with a 28-inch extended length.

The design emphasizes stable support and prevention of accidental closure, making it suitable for demanding environments or frequent-use tonneau covers where extra stiffness is beneficial.
ARANA 20″ 200 LB Gas Struts For Heavy Lids
ARANA’s 20-inch, 200 lb class struts are designed for very heavy lids such as king-size beds, high-load tonneau covers, or large truck tops. They specify compatibility with a broad range of OEM reference numbers and note the need to measure lid weight for correct selection. The product is positioned as a versatile choice for heavier applications where standard 100–120 lb struts may be insufficient.
Buying Guide: Key Considerations For Gas Struts For Tonneau Covers
- Weight and force: Match the lid weight to the force rating. Too light a spring can fail to hold the lid open, while too heavy a spring can cause strain or improper operation.
- Length specs: Confirm extended and compressed lengths align with your mounting points. A mismatch may prevent full opening or cause bracket interference.
- OEM numbers and interchangeability: Use OEM or widely recognized interchange references to ensure compatibility with your tonneau cover model.
- End fittings and mounting style: Verify ball/socket dimensions and the presence of nylon or metal ball joints to fit your brackets and hardware.
- Installation requirements: Some sets include hardware and installation guides; others require separate purchases for brackets or studs. Plan for additional mounting components if needed.
- Environment and durability: For outdoor use, consider corrosion resistance and weather sealing, especially in regions with humidity or road salt exposure.
- Application range: While designed for tonneau covers, these struts also suit truck toppers, RV beds, and other heavy lids with similar mounting geometry.
- Replacement strategy: If replacing one, ideally replace in pairs to maintain balanced lifting and smoothing of operation.
Note: Always cross-check the part numbers against your current gas struts and the tonneau cover model to avoid mismatch. The listings often provide extensive interchange references to aid this alignment, but direct measurement and compatibility confirmation remain essential steps before purchase.
