To provide controlled, assisted lifting and secure holding of hoods, tailgates, and lids, the BDFHYK Gas Spring / Gas Strut / Lift Support replaces worn units on vehicles like the 2015–2020 Ford F-150 and 2011–2019 Ford Explorer as well as universal camper shells and RV doors. Key specifications include a force range of 200–800 N, extended lengths of 350–800 mm, and standard 10 mm ball socket ends. Installation typically takes 15 minutes per strut using basic hand tools. The line covers both universal specification-based gas springs and vehicle-specific replacement types, ensuring correct fit and force for each application.

Installation Overview
- Support the panel. Use a prop rod or an assistant to hold the hood, liftgate, or lid in the fully open position.
- Remove the original gas spring. Release the retaining clips or spring bands at the ball studs using a flat-blade screwdriver; do not reuse worn clips.
- Detach the old unit. Pull the gas spring ends off the ball studs, starting with the upper mount.
- Attach the new BDFHYK Gas Spring / Gas Strut / Lift Support. Press the replacement rod-end and tube-end sockets onto the ball studs until they click securely.
- Secure the clips. Ensure the retaining clips are fully seated in the groove of each ball stud.
- Remove the support and test. Cycle the panel open and closed three times to verify smooth, controlled movement and full-open hold.
Notes
- Torque for mounting fasteners: If the ball stud brackets are replaced, tighten M6 bolts to 10–15 ft-lb (14–20 Nm) per general automotive practice. Confirm the exact specification in the vehicle service manual.
- Common Mistakes: Installing a gas spring with a higher force than the original can make the panel difficult to close, damage hinges, and cause occupant injury. Always match the original equipment force rating. Do not attempt to open, puncture, or heat a gas spring—it is permanently pressurized.
- Diagnostic information: A worn gas spring does not directly trigger an OBD-II powertrain code. However, a hood that fails to close fully can cause a hood ajar warning light. A persistent hood ajar warning may be accompanied by a stored diagnostic trouble code (DTC) such as P0301 (Cylinder 1 Misfire) if the hood latch switch circuit shares a ground with the ignition system. A weak gas spring that prevents full hood closure is a common root cause; verify gas spring operation and hood closure before pursuing engine diagnostics.
FAQs
Q: What is the purpose of a gas spring? A: A gas spring assists in lifting and holding open a panel, such as a hood, liftgate, rear glass, or toolbox lid, using compressed nitrogen gas to provide a controlled outward force.
Q: How do I choose the correct force for my BDFHYK gas spring? A: Match the original equipment force rating printed on the old gas spring (in Newtons) or measure the weight and geometry of the panel. BDFHYK Gas Spring / Gas Strut / Lift Support products are available in forces from 200 N to 800 N to cover common passenger car and light truck applications.
Q: Can I replace a gas spring myself? A: Yes, replacement is a straightforward mechanical task. Always support the panel before removal and work in the order described in the installation overview. The BDFHYK Gas Spring / Gas Strut / Lift Support line uses standard ball socket ends that snap onto the factory studs.
Q: How long do gas springs last? A: A quality gas spring, such as a BDFHYK replacement, typically lasts 5 to 10 years under normal use. Temperature extremes, salt exposure, and high cycle frequency can shorten service life.
Q: What is the difference between a gas spring and a gas strut? A: In automotive and industrial contexts, the terms are often used interchangeably. A gas spring primarily provides lift assistance, while a gas strut may include additional damping. The BDFHYK Gas Spring / Gas Strut / Lift Support is designed to meet both lift and hold functions for vehicle panels and equipment lids.
