folosem Buckle & Strap Assembly Kit for Bakflip MX4 356A0009 — Top & Bottom Replacement, Heavy‑Duty Straps

This folosem 356A0009 buckle and strap assembly kit replaces the top and bottom side fasteners on Bakflip MX4 and compatible folding tonneau covers to restore secure, tensioned fitment.

When a strap frays, a buckle cracks, or the original D-ring hardware wears out, the right replacement parts get your tonneau cover functioning like new. The folosem 356A0009 kit bundles the straps, front and rear buckles, and mounting hardware so you can repair both top and bottom attachments without searching for separate components. Materials and fit are engineered to match OEM expectations for Bakflip MX4 and many aftermarket tri- and quad-fold covers that use the same buckle/strap layout.

How does this kit restore cover tension and stability?

The kit replaces the load-bearing straps and buckles that hold the cover snug against the bed rails and tail area, preventing shifting and vibration while driving. Replacing worn elements returns proper preload to the cover, keeping panels aligned and reducing flap or movement at speed.

• Includes two heavy-duty polyester straps rated for high tension.
• Front and rear buckles engineered to lock reliably under load.
• All mounting hardware provided to refasten top and bottom anchor points.

Will these parts fit my Bakflip MX4 or other tonneau covers?

Yes — the folosem 356A0009 is designed as a direct replacement for OEM part numbers 356A0009, 356A0002, and 356A0003, matching factory dimensions and attachment style. It's also compatible with many aftermarket tri-fold and quad-fold covers that use a similar buckle-and-strap configuration.

• Direct fit for Bakflip MX4 models using those part numbers.
• Meets original factory specifications for top and bottom side assemblies.
• Works with most covers that share the same D-ring/buckle layout.

What materials are used and how do they hold up outdoors?

The straps are woven from industrial-grade polyester webbing chosen for tensile strength and abrasion resistance, while the buckle parts are molded from reinforced ABS plastic for impact and UV resistance. Those materials were selected to resist typical weathering, road salts, and sunlight exposure encountered in daily driving.

• Polyester webbing provides tear resistance and long-term strength.
• ABS buckles resist cracking, UV degradation, and corrosion.
• Hardware is included to maintain a weather-resistant attachment.

How simple is installation and what tools are needed?

Installation is straightforward and intended for do-it-yourself repair: the top buckles mount to the side rails using existing fastener locations, and the bottom buckles attach to the truck bed. No cutting, drilling, or special tools are required — basic hand tools are sufficient and the swap typically takes minutes per side for someone familiar with tonneau hardware.

• Top buckles install with existing mounting points and included hardware.
• Bottom buckles fasten to the bed area and align with the D-ring position.
• Only standard hand tools needed; no permanent modifications required.

Who is this for: Drivers who own a Bakflip MX4 or a compatible folding tonneau cover and need a reliable replacement for worn straps, buckles, or D-ring hardware. The folosem 356A0009 kit is aimed at truck owners who want an OEM-style repair that restores cover tension, improves road stability, and avoids the expense of a full cover replacement. It’s also useful for mechanics and shops performing quick, durable tonneau repairs.
