Installing Your f150 tailgate assist shock: Complete DIY Step-by-Step Guide
Let us turn your heavy, dropping tailgate into a smooth, hands-free opening system.
The classic gravity drop on older or non-assisted trucks is incredibly annoying.
It damages your tailgate hinges, strains the metal cables, and creates a loud boom that wakes up the neighborhood.
This comprehensive tutorial will help you execute a perfect ford f150 tailgate shocks install using basic garage tools.
Required Tools and Preparation
Before beginning, clear a workspace behind your truck and collect the necessary equipment.
You will need a T50 Torx wrench or socket to remove the factory mounting bolts.
You also need a 10mm socket or open-ended wrench to tighten the new ball-mount studs.
Keep a small flathead screwdriver nearby to release the steel spring clips on the damper.
A small tube of blue medium-strength threadlocker is highly recommended for safety.
Lastly, keep some clean microfiber rags and a dab of multipurpose lithium grease close by.
Plan for about 15 to 20 minutes of calm, uninterrupted work in your garage or driveway.
Step 1: Safely Prep and Support the Tailgate
Park your truck on flat, level ground and set your electronic parking brake.
Lower the tailgate fully and support its heavy weight using a jack stand or an assistant.
Disconnect the driver-side safety cable by sliding the metal retaining clip upward and off the shoulder bolt.
Use an assistant to keep the heavy gate from twisting or falling during this step.
Always wear quality safety glasses because metal retaining clips can pop off with high force and cause eye injuries.
Step 2: Install the Lower Bed Pivot Ball
Locate the lower hinge pocket on the driver-side interior bedside wall.
You will see a pre-existing threaded hole intended for tie-downs or accessory mounting.
Apply one drops of blue threadlocker to the thread of the new lower ball stud.
Thread the ball stud into the bedside mount by hand to avoid cross-threading the soft metal.
Tighten the ball stud securely using your 10mm wrench or socket.
Torque the ball stud to exactly 8 ft-lbs to ensure it never backs out over rough terrain.
Be extremely cautious not to over-tighten this bolt because stripping your bedside threads is a costly nightmare to repair.
Step 3: Mount the Upper Tailgate Bracket
Use your T50 Torx driver to loosen and remove the upper factory cable bolt on the tailgate body.
Place the new mounting bracket from your kit directly over the factory bolt hole.
Make sure the upper mounting ball points toward the interior of the truck bed.
Apply a drop of blue threadlocker to the factory T50 bolt threads before reassembly.
Reinstall the T50 Torx bolt through the new bracket and tighten it firmly by hand.
Torque the Torx bolt to 18 ft-lbs according to standard vehicle chassis guidelines.
Step 4: Lubricate and Clip on the Damper Shock
Apply a thin layer of grease inside both socket ends of the new shock absorber.
Identify the correct mounting orientation for your new gas-charged shock cylinder.
The thick barrel body must always point upward, while the thin rod must point downward.
Push the upper socket firmly onto the bracket pivot ball until you hear it click into place.
Snap the lower socket onto the lower bed pivot ball stud until it is fully locked.
Give the shock a gentle tug to confirm the metal spring clips are fully wrapped around the balls.
Step 5: Reconnect and Verify Operation
Reconnect the factory driver-side safety cable back onto its mounting shoulder bolt.
Remove any jack stands or support blocks from beneath your open tailgate.
Slowly raise the tailgate by hand to observe how the new shock compresses.
Check the gap between the shock barrel and the taillight housing to ensure zero rubbing.
Lower the tailgate to verify a smooth, controlled, hands-free descent.
Follow the f150 tailgate assist damper install steps carefully to guarantee long-term operational success.

Understanding F-150 Tailgate Hardware and Engineering Specs
Modern F-150 truck beds are built from high-strength military-grade aluminum alloys.
This structural material change occurred in 2015 to shed weight and improve fuel economy.
However, aluminum requires special mechanical considerations during a ford f150 tailgate assist damper install.
Steel fasteners in contact with aluminum can cause galvanic corrosion over time.
To prevent this, premium damper kits include special coated bolts or synthetic washers.
According to the official Ford service manual, over-tightening steel bolts in aluminum threads can strip them instantly.
This is why using hand tools is always preferred over high-power impact guns for this job.
Consulting resources like the F150Forum highlights how frequently owners strip these delicate mounting points.
Taking your time during the assembly process will save you from the immense frustration of repairing stripped threads.
How Bed Modifications and Accessories Impact Damper Clearances
Before buying a kit, you must analyze your existing bed liners and accessories.
Thick drop-in plastic bed liners can block access to the lower mounting pocket entirely.
You may need to trim a small section of the plastic liner to clear the shock body.
Additionally, trucks equipped with a heavy utility ford f150 tailgate ladder step weigh significantly more.
A standard damper might struggle to slow down a gate carrying this extra integrated weight.
If you have this step, look for heavy-duty nitrogen-charged struts designed specifically for heavy loads.
Be aware that different cabin layouts alter the overall ford f150 bed dimensions across configurations.
However, the driver-side pivot hinge design remains identical on 5.5-foot, 6.5-foot, and 8-foot beds.
Verify that your new f150 tailgate assist damper is rated specifically for your model year.
Struts built for the 2004 to 2014 generation will not fit the 2015 to 2020 or newer models.
Long-Term Maintenance and Cold Weather Performance Tips
Tailgate assist dampers rely on pressurized nitrogen gas and hydraulic fluid inside a sealed tube.
Extreme winter cold will cause the internal hydraulic fluid to thicken significantly.
You will notice the tailgate dropping much slower on freezing mornings than in summer.
Do not force the tailgate down manually to speed up its slow winter descent.
Forcing the piston can rupture the delicate rubber seals and ruin the damper.
Once a seal is blown, hydraulic fluid will leak out and the shock will lose all dampening force.
Inspect the chrome piston rod once a month for dirt, road grit, or salt buildup.
Wipe the rod clean with a dry microfiber cloth to keep dirt out of the seal.
A light spray of dry silicone lubricant on the joint ball sockets keeps operation silent.
Avoiding the Top DIY Installation Blunders
The most common DIY error is installing the hydraulic cylinder upside down.
Always orient the shock so the thick reservoir barrel body is mounted on the upper tailgate bracket.
This design keeps the internal oil resting against the main seal during daily driving.
Another frequent mistake is neglecting to use threadlocker on the ball-mount studs.
Road vibrations on gravel paths can easily back these un-locked studs out over time.
A loose ball stud will quickly bend your mounting brackets or damage your aluminum paint.
Finally, never operate your tailgate if the steel safety cable is disconnected or broken.
The helper shock is designed to slow the gate, not support its full weight alone.
Frequently Asked Questions
Will installing an aftermarket tailgate shock void my factory Ford warranty?
No, installing an aftermarket assist damper will not void your factory truck warranty.
The federal Magnuson-Moss Warranty Act protects consumers from unfair warranty denials by manufacturers.
The dealership must prove that your custom part directly caused a failure to deny any claim.
However, physical damage caused by improper DIY installation steps is not covered under warranty.
Save yourself from unnecessary dealership disputes by following our step-by-step instructions carefully.
Do I need to install a helper shock on both sides of my tailgate?
No, a single high-quality damper on the driver side is fully sufficient to control descent.
Almost all aftermarket kits are designed to install on the left side of the bed.
Adding a second cylinder to the passenger side is unnecessary and counterproductive.
Two shocks will create too much mechanical resistance, making the tailgate difficult to close.
How long do these tailgate assist shocks last before needing replacement?
A quality gas-charged strut typically lasts between three and five years of regular use.
This lifespan depends heavily on your local weather, salt exposure, and daily tailgate cycles.
Signs of failure include oily film on the metal shaft or a sudden return of the heavy drop.
Replacing a worn-out cylinder is simple and takes less than five minutes using your original brackets.
