Buying Guide
Key factors when selecting 12-inch gas struts for lifted setups:
- Weight rating: Match the lid or door weight to the per-shock force. For heavier lids, choose 40–100 Lb per shock; for lighter lids, 10–24 Lb may suffice.
- Length tolerances: Ensure extended and compressed lengths fit your opening without binding or leaving gaps.
- Mounting hardware: Check whether ball studs or brackets are included. Some listings omit studs—plan for compatible hardware.
- Interchange compatibility: OEM reference numbers help verify fit with Leer, ARE, Snugtop, and Weatherguard components.
- Installation ease: Many 12-inch struts can be swapped in minutes with basic tools; some listings offer online installation guidance.
- Quantity: If replacing both sides, buy two shocks to ensure balanced support and even lifting.
- Warranty and service: Look for suppliers offering warranties or responsive customer service for possible issues.
- Material and durability: Consider corrosion resistance if you frequently operate in harsh or humid environments.
Additional Considerations
- OEM compatibility vs. universal fit: OEM-numbered parts may guarantee a closer match to your current hardware, while universal options offer broader compatibility.
- Noise and smoothness: Some models emphasize smoother action and quieter operation, which can enhance daily use.
- Availability of replacement parts: Check whether replacement shocks or studs are readily available from the seller or third parties.
