Sea-Dog Gas Filled Lift Spring - 10" - 40#

The Sea-Dog Gas Filled Lift Spring – 10" – 40# is a precision support component designed for marine and automotive applications where controlled weight assistance and smooth actuation are essential. This gas spring is ideal for providing reliable support for lids, hatches, tonneau covers, and cabinets, particularly in environments subject to high vibration or frequent use.

Constructed with a hardened steel cylinder filled with compressed nitrogen, this lift spring offers a stable linear force curve that remains consistent across temperature variations and usage cycles. Unlike traditional coil springs, which may sag or weaken over time, this gas spring ensures dependable performance without the maintenance issues associated with mechanical springs.

The 10-inch extended length and 40-pound force rating make this lift spring suitable for medium-duty applications, providing controlled opening assistance without overpowering the system. Its compact design allows for easy installation in tight spaces, making it a valuable addition for automotive enthusiasts and fabricators looking to enhance their projects.
