What’s included in this hardware kit

Complete Hardware Components & Materials
This hardware kit contains every mounting component required for BakFlip MX4 installation. The package includes four main bed rail clamps manufactured from heavy-duty stainless steel with powder-coated finishes that resist rust and corrosion. Each clamp features precision-machined threads and contact points that grip your truck bed rails securely without scratching factory paint.
We include reinforced aluminum mounting brackets designed to distribute tonneau cover weight evenly across your bed rails. The brackets arrive pre-drilled and contoured to match standard pickup bed profiles, eliminating the need for custom modifications. All fasteners are grade 8 bolts with lock washers to prevent loosening from road vibration. Our MX4 tonneau cover relies on these components for the structural integrity that keeps your cargo protected mile after mile.

Installation Process & Compatibility
Installing the MX4 Hardware Kit requires only basic hand tools and takes approximately 30 minutes for most truck owners. Begin by positioning the bed rail clamps at the front and rear corners of your truck bed, ensuring they align with the pre-marked mounting points on your BakFlip panels.
Step-by-Step Installation
Secure each clamp using the provided bolts and washers, tightening to 15-20 ft-lbs of torque as specified in our installation guide. Attach the aluminum mounting brackets to the clamps, then verify all hardware sits flush against the bed rails before final tightening. The kit works with all BakFlip MX4 models across Ford, Chevy, RAM, Toyota, and Nissan truck beds from 5.5 to 8 feet in length. For model-specific guidance, consult our truck bed covers compatibility chart before ordering.
Replacement & Maintenance Guidelines
We recommend inspecting your MX4 hardware every six months for signs of wear or corrosion, especially if you frequently drive in wet or winter conditions. Replace any clamps showing thread damage or brackets with visible cracks to maintain your tonneau cover’s weather seal and security.
The stainless steel components in this kit typically last 5-7 years under normal use, though harsh environments may accelerate wear. Apply a thin coat of marine-grade grease to bolt threads during installation to prevent seizing and simplify future maintenance. If you notice your tonneau cover shifting or gaps appearing along the bed rails, tightening the hardware often resolves the issue before replacement becomes necessary. Our installation accessories section offers additional tools and lubricants designed for BakFlip product care.

BakFlip MX4 Hardware Kit Questions
The BakFlip MX4 Hardware Kit is compatible with all BakFlip MX4 tonneau covers across Ford, Chevy, RAM, Toyota, Nissan, and GMC trucks with bed lengths from 5.5 to 8 feet. The universal clamp design adjusts to fit standard bed rail profiles on models from 2004 to present. If you have a custom bed liner or non-standard bed configuration, contact our support team to verify fitment before ordering.
Most truck owners complete the hardware installation in approximately 30 minutes using basic hand tools. The process involves positioning four clamps on your bed rails, attaching mounting brackets, and tightening bolts to the specified torque. First-time installers may need up to 45 minutes, while experienced DIYers often finish in 20 minutes. We include step-by-step instructions with diagrams that guide you through each stage of the installation.
You’ll need a socket wrench set with 10mm and 13mm sockets, a torque wrench capable of 15-20 ft-lbs, and a flathead screwdriver for positioning the rail guards. We recommend having a helper to hold the tonneau cover panels while you secure the hardware, though the job can be completed solo. No drilling or permanent modifications to your truck bed are required for installation.
Yes, we offer individual clamps, brackets, and fasteners through our parts catalog if you only need to replace one or two components. However, the complete hardware kit provides better value when replacing multiple worn pieces or setting up a new installation. Our clamp assembly and individual bracket listings are available in the installation accessories section of our site.
Inspect your MX4 hardware every six months for visible cracks in mounting brackets, stripped threads on clamps, or corrosion that compromises the finish. If your tonneau cover shifts during driving or you notice gaps along the bed rails, loose or worn hardware is typically the cause. Any clamp that no longer tightens securely should be replaced immediately to maintain your cover’s weather seal and cargo protection.
All BakFlip MX4 Hardware Kit components are covered by our standard 2-year limited warranty against manufacturing defects. This warranty covers material failures and workmanship issues but does not extend to normal wear from use or damage from improper installation. Register your hardware kit within 30 days of purchase through our website to activate full warranty coverage and access expedited replacement service if needed.
The kit includes rubber rail guards that create a protective barrier between the metal clamps and your truck bed’s painted surface. These guards distribute clamping pressure evenly and prevent scratching during installation and normal use. We recommend cleaning your bed rails thoroughly before installing the hardware to remove any debris that could cause abrasion over time.
