The BDFHYK Replacement Gas Spring is a sealed, nitrogen-charged lift support for hoods, tailgates, and hatches on vehicles such as the 2015-2020 Ford F-150 and 2018-2023 Jeep Wrangler JL. With a force range of 100–250 lb (445–1112 N) and direct-fit ball-socket ends, installation typically takes 15–30 minutes per pair. Most replacement gas springs are non-adjustable; only industrial models with a release valve are designed for safe pressure reduction.

Installation Overview
Removing a Sealed Gas Spring (BDFHYK Replacement Gas Spring)
- Secure the panel – Prop the hood, trunk, or hatch with a rigid support rod to prevent sudden closure. Never rely on a single gas spring to hold the panel open.
- Locate the retaining clips – Each end of the gas spring has a spring-steel retaining clip or a wire bail. Identify the clip type: flat spring clip, wire loop, or ball-socket pop-on.
- Release the clip – Insert a flat-blade screwdriver under the retaining clip and gently pry outward. For wire-loop clips, squeeze the loop with pliers to spread it. Do not deform the clip.
- Pop the socket off the ball stud – Once the clip is released, slide the socket end off the ball stud. Work from the body-side mount first, then the panel-side mount.
- Remove the second gas spring – If the panel uses two gas springs, always replace them in pairs. Follow the same procedure for the opposite side.
- Inspect the mounting points – Check ball studs for corrosion, looseness, or thread damage. Torque replacement ball studs to the vehicle manufacturer’s specification (commonly 15–25 ft-lb for an M8 stud).
Adjusting Force on an Industrial Gas Spring with a Release Valve
Only models explicitly labeled as adjustable, fitted with a Schrader valve or set-screw release, can be bled. The BDFHYK Replacement Gas Spring is a sealed automotive unit and does not contain a release valve. Misapplication of the steps below can cause a high-pressure rupture.
- Confirm the gas spring type – Look for a threaded brass valve stem or a small hex-set screw on the body. If none is present, stop; the unit is a sealed replacement gas spring and is non-adjustable.
- Depressurize safely – Wear safety glasses and gloves. Mount the gas spring in a vise using soft jaws. Slowly depress the valve core with a blunt tool, allowing nitrogen to escape in short bursts.
- Measure force – After each brief release, cycle the rod several times to homogenize the oil charge, then measure force on a spring tester. Repeat until the desired force is reached.
- Reseal and verify – Ensure the valve is fully closed and no leakage is detected with soapy water. Mark the new force rating on the label.
Notes
- Common mistake: Drilling or grinding a sealed replacement gas spring to release gas. The BDFHYK Replacement Gas Spring, like most automotive replacement gas springs, is a sealed unit under high pressure; puncturing can cause explosive decompression and severe injury. Replace a weak gas spring instead of attempting to refill or modify it.
- OBD-II codes: Gas springs are mechanical components with no electronic sensors. No OBD-II diagnostic trouble codes (P0000–P2999) are associated with lift support failure. An illuminated trunk-open warning on the instrument panel is typically triggered by the latch switch, not the gas spring.
- Temperature effect: Gas spring output force decreases by approximately 5% per 10°C drop in temperature. A strut that feels weak in cold weather may still meet specification. Always test at 20°C ambient before condemning.
- Pair replacement: Always replace gas springs in pairs on the same panel. Uneven force from a new and old strut can twist the panel and cause hinge damage over time.
- The BDFHYK Replacement Gas Spring must be mounted with the rod facing downward to keep the seal lubricated and extend service life.
FAQ
Q: Can I release pressure from a BDFHYK Replacement Gas Spring to reduce lifting force? A: No. The BDFHYK Replacement Gas Spring is a sealed, non-adjustable automotive lift support. It does not contain a release valve. Attempting to release pressure will destroy the unit and create a safety hazard.
Q: How do I safely remove a gas spring from a tailgate? A: Prop the tailgate with a support rod, pry the retaining clips loose with a small screwdriver, and pop the sockets off the ball studs. Always release the body-side end first to maintain control of the panel.
Q: Why does my gas spring feel weak in winter? A: Nitrogen pressure drops with temperature. A force reduction of 10–15% from 20°C to -10°C is normal. The gas spring will recover as the ambient temperature rises. If it remains weak at room temperature, replace the BDFHYK Replacement Gas Spring pair.
Q: What torque should I use for gas spring mounting bolts? A: Typical torque values are 8–10 ft-lb for M6 fasteners and 18–22 ft-lb for M8 fasteners. Confirm the exact specification for your vehicle in the factory service manual.
Q: Is there an OBD-II code for a failed gas spring? A: No. Mechanical gas springs do not communicate with the vehicle’s diagnostic system. A trunk-lid warning light points to the latch position sensor, not the gas spring.
