The 20" 120 lb Heavy-Duty Gas Strut Lift Support delivers powerful lifting and holding assistance for compatible heavy doors, hatches, lids, storage compartments, and access panels.
With a substantial 120-pound force rating, this gas strut is designed for demanding applications requiring significantly more lifting assistance than standard light- or medium-duty gas springs.
Its 20-inch length provides extended reach for larger doors and hatches while maintaining the high lifting force required for heavier applications.
The strut features 10mm socket-style ends designed for compatible 8mm x 18mm ball studs. The larger stud configuration makes verifying the mounting hardware especially important when replacing an existing gas spring.
For RVs and motorhomes, potential applications include compatible large baggage doors, exterior storage compartment doors, equipment compartments, access hatches, and other heavy hinged panels.
For trailers, this heavy-duty lift support may be suitable for compatible cargo trailers, enclosed trailers, equipment trailers, utility trailers, concession trailers, toy haulers, and specialty trailer applications.
The combination of a 20-inch length and 120-pound force rating can also make this gas spring useful for compatible automotive, truck, utility, industrial, and specialty-equipment applications requiring substantial lifting assistance.
Gas struts can gradually lose pressure and lifting ability through age and repeated operation. When a heavy door or hatch begins to drop, sag, or no longer remain securely supported, replacing the worn gas spring with a correctly matched lift support can help restore its intended operation.
Because this is a 120 lb high-force gas strut, selecting the correct replacement is particularly important. A strut with insufficient force may not support the application, while excessive force can make the door difficult to close or place unnecessary stress on hinges, mounting brackets, studs, and surrounding structures.
For replacement applications, match the force rating, extended and compressed dimensions, socket size, ball-stud dimensions, mounting locations, and installation geometry rather than selecting a gas strut based solely on overall length.
Whether you're replacing a worn RV baggage-door lift support or supporting a heavy trailer hatch, this 20" 120 lb Gas Strut with 10mm Socket Ends provides substantial lifting force for compatible heavy-duty applications.

Applications & Compatibility
Designed for compatible applications requiring a 20-inch, 120-pound gas strut with 10mm socket ends and 8mm x 18mm mounting studs.
Potential applications include RV baggage doors, motorhome storage compartment doors, trailer hatches, cargo trailer doors, enclosed trailer doors, toy hauler compartments, equipment compartments, storage lids, access panels, automotive compartments, utility equipment, and specialty vehicles.
The combination of 20" length and 120 lb force makes this version particularly suitable for compatible larger and heavier applications requiring both extended reach and substantial lifting assistance.
Fitment Note: This gas strut uses an 8mm x 18mm stud configuration, which differs from the 6mm x 15mm configuration used on many smaller gas struts. Verify the 20" length, 120 lb force rating, 10mm socket ends, 8mm x 18mm stud requirements, compressed and extended lengths, mounting points, bracket strength, and installation geometry before ordering.
