Buying Guide: Key Purchase Considerations And Comparisons
Length and fit: For long lids, choose struts whose extended length closely matches the lid’s travel. Ensure compressed length fits the hinge geometry and mounting points. Measure the side length of the lid to confirm suitability with 50 inches or longer guidance where applicable.
Lift force: Select a pair that matches lid weight. A lid in the 80–120 lb range typically needs 40 lb per strut, while heavier lids (130–220 lb) may require 150–200 lb per strut. Using too little lift results in slow opening or failure to hold the lid open; too much can strain mounting hardware.
Mounting compatibility: Check end fittings (10 mm ball studs, 13 mm ball joints) and thread types. Confirm OEM numbers or model compatibility to avoid mismatches. Pair-based sets are standard; mixed-length or mismatched forces should be avoided for balanced operation.
Application and environment: Consider whether the lid is used indoors, outdoors, or in harsh weather. UV resistance, corrosion resistance, and temperature tolerance can impact performance and longevity. For outdoor or RV use, choose models rated for wide temperature ranges and exposure.
Installation ease: Many models advertise easy installation with basic tools. A flat-head screwdriver or standard mounting hardware is often sufficient. Review installation diagrams and confirm hinge spacing to ensure a clean, secure fit.
Durability and warranty: Look for solid cylinder construction, smooth action, and a warranty that covers common wear and tear. Durable struts resist bending and maintain consistent force over time, especially for frequent frequent lid use.
