How to Successfully Complete Your Ford F150 Tailgate Assist Damper Install

Lowering your tailgate should not feel like an unexpected physical challenge.
Many truck owners feel immense frustration when the heavy steel gate drops violently.
This abrupt drop risks damaging your cargo and injuring anyone standing nearby.
Fortunately, completing this project allows you to open your truck bed safely with a single hand.
Required Tools and Project Preparation
Before you begin, gather the essential tools for a smooth upgrade process.
You will need a T50 Torx wrench to remove the factory hinge bolts.
A 10mm socket wrench is required to mount the new assist brackets.
Keep a flathead screwdriver close by to adjust the metal retainer clips during mounting.
This entire DIY project takes roughly fifteen minutes of your time in the driveway.
-
Step 1: Secure the Tailgate and Prep the Work Area
Ensure your F-150 is parked on a completely level surface.
Open the tailgate and support its weight with a sturdy box or a helper.
Supporting the gate protects your hinges while you remove the heavy support cables.
Safety is paramount when working with heavy steel and aluminum truck panels.
-
Step 2: Detach the Passenger Side Support Cable
Locate the steel support cable on the passenger side hinge.
Use a flathead screwdriver to gently pry the metal retaining clip open.
Slide the support cable away from the mounting stud carefully.
Keep this sequence in mind to make your f150 tailgate assist damper install easy and efficient.
-
Step 3: Mount the Lower Ball Hinge Bracket
Use your T50 Torx wrench to back out the lower hinge pivot bolt.
Align the new lower mounting bracket with the exposed factory bolt hole.
Reinstall the factory Torx bolt and hand-tighten it to prevent cross-threading.
Torque the bolt to exactly 22 foot-pounds using your manual torque wrench.
-
Step 4: Secure the Upper Ball Stud
Locate the small utility hole in the side of your truck bed wall.
Insert the expanding blind nut assembly into this hole carefully.
Tighten the bolt with your 10mm wrench until the nut expands and locks in place.
This creates a permanent, solid mount for your new hydraulic hardware.
-
Step 5: Snap the Hydraulic Damper Shock into Place
Unpack your new f150 tailgate assist shock cylinder.
Orient the shock with the wider cylinder body pointing upward toward the bed.
Press the socket onto the upper ball mount until you hear a clear snap.
Push the lower socket onto the hinge ball bracket to complete the installation.
Completing a DIY project like this saves you from paying exorbitant dealer labor fees.

Understanding Tailgate Mechanics: Cable Tension vs. Hydraulic Damping

Standard steel support cables are designed to stop the tailgate at its lowest point.
However, they do nothing to slow down the acceleration of the drop.
This rapid drop creates a massive shock load on your vehicle’s metal hinges.
Over time, this dynamic force causes structural fatigue in the hinge mounts.
This fatigue is especially problematic for aluminum-bodied trucks built after 2015.
Installing a high-quality f150 tailgate assist damper solves this stress problem completely.
The hydraulic system absorbs the kinetic energy of the falling metal gate smoothly.
This reduces the peak tension on your steel support cables by up to ninety percent.
Think about how much money you save by protecting these expensive structural parts.
When planning a ford f150 tailgate assist shock install, choose parts built with weather-resistant steel.
OEM Housed Systems vs. Aftermarket External Shock Kits
Many truck owners debate whether to buy factory parts or aftermarket alternatives.
Ford offers an OEM system that mounts inside the rear taillight cavity.
This setup is invisible and protects the damper from cargo scrapes.
However, it requires removing the entire taillight assembly during installation.
This extra step can be intimidating for owners who fear breaking delicate plastic clips.
On the other hand, external aftermarket kits mount quickly on the outer hinge pivot.
This exterior setup is highly accessible and takes half the installation time.
It remains the ideal choice for a quick and rewarding afternoon project.
This is especially true if you are already managing your ford f150 bed dimensions with a thick bed liner.
Many aftermarket kits are designed to fit perfectly around modern spray-in bed liners.
Keep this in mind during your next f150 tailgate assist damper install project.
Maintenance Tips for Long-Term Shock Durability

Your hydraulic damper works hard in all seasonal weather conditions.
Extreme winter cold can thicken the internal fluid and slow down operation.
Conversely, summer heat can thin the fluid and make the drop slightly faster.
Wipe the piston rod clean with a microfiber cloth every few months.
This simple step prevents dust and road grit from tearing the internal rubber seals.
A damaged seal will cause the hydraulic fluid to leak out completely.
Once the fluid leaks, the shock loses all dampening capability.
Apply a tiny drop of silicone grease to the ball sockets once a year.
This ensures quiet operation and prevents annoying squeaks when loading cargo.
Completing these steps after a ford f150 tailgate assist shock install will double the lifespan of your part.
| Feature | OEM Ford Kit | Aftermarket External Kit |
|---|---|---|
| Mounting Location | Inside taillight cavity (hidden) | Outside hinge assembly (visible) |
| Difficulty Level | Moderate (requires taillight removal) | Very Easy (simple bolt-on) |
| Installation Time | 30 to 45 minutes | 10 to 15 minutes |
| Average Cost | $60 to $80 | $25 to $40 |
Overcoming Critical Installation Errors
The most common DIY mistake is installing the hydraulic cylinder upside down.
The thick black body of the shock must always connect to the truck bed frame.
The thin metallic shaft must point downward toward the lower tailgate hinge.
This specific orientation ensures that the internal oil lubricates the piston seals correctly.
Installing the shock upside down will dry out the seals quickly.
This dry friction leads to rapid failure of the internal pressurization chamber.
Another common mistake is stripping the factory T50 Torx head bolt during removal.
Ensure your Torx bit is fully seated into the bolt head before applying torque.
We recommend using a manual breaker bar instead of a high-torque power impact wrench.
A manual tool gives you better feedback and protects your vehicle’s factory threads.
Paying attention to these details ensures success during your f150 tailgate assist damper install steps.
You will avoid the costly headache of dealing with stripped steel fasteners in your truck frame.
Frequently Asked Questions
Does installing a tailgate assist void my Ford factory warranty?
No, installing an aftermarket tailgate damper does not void your bumper-to-bumper warranty.
The Magnuson-Moss Warranty Act protects consumers from having warranties voided by non-OEM parts.
However, Ford will not cover the aftermarket shock itself if it fails over time.
Always buy from trusted brands to secure your long-term peace of mind.
Can I install a damper if my truck has a factory tailgate step?
Yes, dampers are fully compatible with models featuring an integrated step.
A ford f150 tailgate ladder step adds significant weight to the assembly.
This extra weight makes a hydraulic assist shock even more necessary for daily use.
The shock will easily handle the added weight and slow down the drop rate safely.
Be sure to complete a ford f150 tailgate assist shock install to protect your hands.
How long do these hydraulic shocks typically last?
A quality tailgate shock usually lasts between three and five years under normal conditions.
Its lifespan depends heavily on your local weather patterns and usage frequency.
Trucks operated in cold northern climates may experience faster wear on internal rubber seals.
Regular cleaning of the piston shaft will extend the lifespan of the shock significantly.
