What Does the Tailgate Assist Shock Do?
The tailgate assist shock—sometimes called a slam damper or "invisible hand"—is a hydraulic cylinder mounted inside the tailgate that controls descent speed when the tailgate is released. When you unlock and lower the tailgate, the assist shock provides resistance, slowing the fall from vertical to horizontal and preventing a sudden drop.
Without a functioning assist shock, the tailgate crashes open against its chains or stops, potentially causing:
- Bent or broken tailgate hinges
- Stretched or snapped safety chains
- Dents or scratches on the tailgate lower edge or bumper
- Damage to cargo or objects positioned behind the truck
- Injury risk to hands, feet, or nearby individuals
The APDTY 162607 restores controlled, predictable tailgate operation and protects both the vehicle and operator.
What Are the Symptoms of a Failed Tailgate Assist Shock?
Tailgate assist shocks fail gradually or suddenly due to seal wear, fluid loss, or internal piston damage. Common symptoms include:
- Tailgate drops rapidly: No resistance when opening; tailgate slams down hard
- Tailgate requires manual support: You must hold the tailgate to prevent it from crashing open
- Visible oil or fluid: Hydraulic fluid leaking from shock body or rod seal
- Rod extending from shock housing: Shock appears collapsed or fully extended when tailgate is closed
- Loud bang or clunk: Tailgate hits stops violently when released
If you notice any of these signs, the assist shock has likely lost internal pressure and requires replacement. Continuing to operate with a failed shock accelerates wear on hinges and latches.

How to Install the Tailgate Assist Shock
Replacing the tailgate assist shock is a straightforward mechanical task suitable for DIY enthusiasts with basic tools. General installation steps:
- Open and support the tailgate: Lower the tailgate fully and use a jack stand, helper, or block to hold it horizontal during removal.
- Locate the old shock: The assist shock mounts inside the tailgate, typically visible when the tailgate is open. Access may require removal of an inner trim panel or cover.
- Disconnect the shock: Remove the mounting bolts or clips at both ends (upper and lower mounts). Note the orientation and hardware configuration.
- Install the new APDTY 162607: Position the new shock in place, install the provided hardware, and torque fasteners to manufacturer specifications (consult a service manual for exact values).
- Test operation: Reinstall any trim panels, then carefully release the tailgate. It should descend smoothly and controllably. Repeat the test several times to confirm proper function.
Safety note: The tailgate is heavy and can cause injury if it falls unexpectedly. Always support the tailgate securely during removal and installation. Wear safety glasses and gloves when working with hydraulic components.
