Complete Step-by-Step DIY Guide for Ford F150 Lift Kits 6 Inch
Installing a massive ford f150 suspension lift kits system is a serious undertaking.
You should allocate between 8 and 12 hours of working time in a spacious garage.
Having a second set of hands will make heavy lifting much safer.
Ensure that you have all necessary safety gear, including high-capacity jack stands, heavy-duty jacks, and protective eyewear.
Prerequisites & Tools Needed
- Hydraulic floor jack and high-capacity jack stands rated for at least 3 tons.
- Complete metric socket set (ranging from 10mm to 30mm sizes).
- Calibrated torque wrench capable of reaching up to 250 lb-ft.
- Ball joint separator tool and a heavy brass mallet.
- Reciprocating saw or angle grinder with metal cutting discs.
- Pneumatic impact gun to speed up stubborn suspension fasteners.
- Coil spring compressor tool (if you are reusing your factory front springs).
Step-by-Step Instructions
-
Step 1: Vehicle Preparation and Front End Disassembly
Park your truck on a flat, level concrete surface and engage the emergency parking brake.
Disconnect the negative battery terminal to protect the sensitive Electronic Power Assisted Steering (EPAS) rack from electrical surges.
Loosen the lug nuts on the front wheels before lifting the truck off the ground.
Raise the front of the vehicle and place heavy-duty jack stands under the frame rails for complete stability.
Remove the wheels, front brake calipers, brake rotors, and the ABS (Anti-lock Braking System) speed sensors safely.
Be careful not to stretch or kink the delicate rubber brake lines during this phase.
-
Step 2: Removing OEM Knuckles, Tie Rods, and Front Struts
Support the lower control arm using a reliable hydraulic floor jack.
Loosen the tie rod end nut and use a ball joint separator to free the tie rod from the steering knuckle.
Remove the upper and lower ball joint nuts to completely disconnect the factory steering knuckle.
Carefully slide the CV (Constant Velocity) axle shaft out of the hub assembly and set it aside.
Remove the upper mounting nuts and lower mounting bolts securing the OEM (Original Equipment Manufacturer) front struts.
Drop the factory strut assembly down and set it aside if you plan to install upgraded ford f150 coilovers.
-
Step 3: Cutting the Frame and Lower Crossmember Modification
Most 6-inch kits require cutting the rear factory lower control arm pocket to allow clearance for the new dropped differential.
Mark the cutting lines on the rear crossmember pocket according to the manufacturer specification template.
Use a reciprocating saw or angle grinder to carefully cut away the specified section of the metal frame.
Always wear protective safety goggles and heavy gloves when cutting the structural frame of your truck.
De-burr the freshly cut metal edges and apply high-quality rust-preventative paint to stop future corrosion.
Install the new differential drop brackets using the provided high-grade hardware.
-
Step 4: Installing the Heavy-Duty Drop Brackets and New Knuckles
Bolt the new front and rear high-clearance crossmembers into the factory lower control arm pockets.
Mount the lower control arms into the new dropped crossmember assemblies.
Secure your new lifted strut assemblies or lift spacers onto the upper strut mounts.
Attach the new extended steering knuckles to the lower control arm ball joints.
Slide the CV axle shaft back into the new hub assembly, ensuring proper alignment of the splines.
Connect the upper control arm ball joint to the new extended knuckle and tighten all fasteners to the specified torque values.
-
Step 5: Rear Lift Block and Shock Absorber Installation
Chock the front wheels securely, lift the rear of the truck, and support the frame with jack stands.
Position the floor jack under the rear axle housing to support the weight of the differential.
Remove the rear U-bolt nuts and take off the factory U-bolts and spring plates.
Lower the axle slowly to make space for the new 6-inch lift blocks.
Insert the new lift blocks between the leaf pack and the axle pad, ensuring the built-in taper faces the front to protect your driveshaft angle.
Install the new extended U-bolts and tighten them in a crisscross pattern to secure the rear suspension.
Replace the factory rear shocks with the new extended-travel shocks included in your kit.

Steering Geometry and CV Axle Angles on a Ford F150 6 Inch Lift
Lifting a truck changes the complex engineering dynamics of your front suspension.
A simple ford f150 leveling kits system merely pushes the factory strut down to level the stance.
This basic approach works fine for small heights, but a larger lift demands physical corrections.
When you install a complete ford f150 6 inch lift, the front differential must be physically lowered.
Without differential drop brackets, your CV axles would operate at harsh, steep angles.
These severe angles would quickly tear rubber CV boots and cause catastrophic driveline vibration.
Our mechanical analysis confirms that a proper f150 6 inch lift kit corrects these angles with dropped crossmembers.
This computer-aided design (CAD) technology keeps your front axles operating parallel to the ground.
This design maintains a smooth factory ride and prevents expensive wear on your front-wheel hub assemblies.
Furthermore, standard steering knuckles are replaced with extended, taller knuckles in a quality 6-inch kit.
Taller knuckles preserve the correct tie rod angles to eliminate dangerous bump steer on rough roads.
Understanding these geometric differences helps you select the correct setup for your driving needs.
| Lift Style | CV Axle Angle Strain | Recommended Max Tire Size | Ride Quality Preservation |
|---|---|---|---|
| 2-Inch Leveling Kit | Moderate | 33 Inches | Excellent (OEM Strut Retained) |
| 3-Inch Strut Lift | High | 34 Inches | Firm (Angles Stretched) |
| 6-Inch Drop Bracket Kit | Minimal (Corrected) | 35 – 37 Inches | Very Smooth (Full Correction) |
Tires, Clearances, and Sync 4 Integration for a Lifted F150
Upgrading to a 6 inch lift f150 allows you to fit aggressive 35-inch or 37-inch mud-terrain tires.
However, running wider tires requires careful consideration of wheel offset and backspacing.
A wheel with negative offset pushes the tire outward, providing necessary clearance from the new steering knuckle.
Using the wrong wheel offset can cause the tires to rub against the metal frame at full steering lock.
Beyond mechanical clearances, lifting your truck alters several highly integrated electronic systems.
The modern F-150 platform relies on front-facing cameras and radar sensors for driver-assist safety systems.
A tall ford f150 6 inch lift changes the camera height and angle of view relative to the pavement.
Your Lane-Keeping Assist and Pre-Collision Assist systems require physical sensor recalibration after a lift is installed.
Additionally, your GPS navigation and odometer will display incorrect speeds due to the larger tire diameter.
You can easily correct this tire size mismatch using FORScan software or a plug-and-play speedometer calibrator.
Updating your tire diameter in the truck’s engine control module ensures your Sync 4 navigation calculates routes accurately.
It also keeps your smart Pro Power Onboard system functioning perfectly by monitoring engine load correctly.
Proper electronic calibration ensures your safety systems remain fully active to protect you on public roads.
Post-Installation Maintenance: Alignment and Torque Specifications
Completing your suspension install is only half the battle of a successful build.
You must schedule a professional ford f150 front leveling kit alignment immediately after finishing the mechanical assembly.
A proper wheel alignment corrects the camber, caster, and toe settings that are severely altered by a lift.
Skipping a professional alignment can ruin your brand-new off-road tires in less than 1,000 miles.
Additionally, suspension components will settle after driving the vehicle for the first time.
You must perform a complete torque check on all newly installed suspension bolts after the first 100 miles.
Pay close attention to the massive rear U-bolts and the lower control arm mounting fasteners.
Re-torque these critical fasteners to the exact manufacturer specification to prevent dangerous component shifting.
Conducting these preventative checks regularly ensures your custom truck remains reliable on long road trips.
How to Avoid Catastrophic DIY Lift Kit Mistakes
Many amateur mechanics make a critical error by tightening suspension bushings while the truck is still raised on jack stands.
Tightening suspension bolts while the suspension is fully drooped locks the rubber bushings into an unnatural position.
Once the truck is lowered, the bushings remain twisted and will fail prematurely from constant stress.
Always wait until the truck is sitting under its own weight on the ground before performing final torque steps.
Another common mistake is ignoring the length of the ABS speed sensor wires and brake lines during knuckle installation.
Stretching these fragile wires can trigger warning lights on your dashboard and disable your traction control.
Utilize the brake line relocation brackets included in your f150 6 inch lift kit to guarantee ample slack at full steering lock.
Taking these extra precautions saves you from expensive electrical diagnostics at the local repair shop.
Frequently Asked Questions
Will installing a 6-inch lift kit void my Ford factory warranty?
Installing an aftermarket lift kit does not automatically void your entire vehicle warranty under federal law.
However, if a lift component causes a factory part to fail, Ford can deny coverage for that specific repair.
For example, if your lifted stance causes premature wheel bearing wear, that repair won’t be covered under warranty.
Always select high-quality kits and keep detailed receipts to protect your warranty rights.
What is the maximum tire size I can run with a 6 inch lift f150?
A quality 6-inch suspension lift allows you to run up to 35-inch tires with zero trimming required.
You can fit larger 37-inch tires if you use wheels with the correct offset and perform minor plastic trimming.
Be sure to consult with your kit manufacturer to verify backspacing specs before purchasing custom wheels.
Can I still tow my trailer safely after lifting my truck?
Yes, you can tow after installing a 6-inch lift kit, but your overall towing capacity may be slightly reduced.
The raised center of gravity increases body roll, so you must use a heavy-duty drop hitch to keep your trailer level.
We recommend adding rear helper airbags or upgraded leaf springs to prevent sag when hauling heavy payloads.
Do I need to replace my factory drive shafts with a 6-inch lift?
Most complete 6-inch kits are designed to work perfectly with your factory front and rear driveshafts.
The differential drop brackets keep the front driveshaft angle well within safe operational limits.
For some long-bed models, you may need a carrier bearing spacer to eliminate minor high-speed driveshaft vibrations.
