folosem Buckle & Strap Assembly Kit 356A0009 — Top & Bottom D‑Ring Replacement, Reinforced ABS & Polyester

Replacement buckle and strap assembly that restores tension and secure fastening for Bakflip MX4 and similar folding tonneau covers.

This folosem 356A0009 kit supplies the top- and bottom-side straps, buckles and hardware you need to replace worn or damaged D‑ring style fasteners on Bakflip MX4 tonneau covers and many aftermarket tri‑fold or quad‑fold systems. Built with reinforced ABS buckles and industrial polyester webbing, the set mirrors factory fit and function so you can quickly regain a snug, rattle‑free cover without altering rails or drilling new holes.

How does this kit match OEM parts and fit my Bakflip MX4?

The folosem kit is engineered to match original dimensions and attachment points for direct swap‑in replacement of common OEM part numbers 356A0009, 356A0002, and 356A0003. No modification to the cover or truck rails is required when your cover uses the same D‑ring buckle configuration.

• Direct-fit components made to the same form factor as factory parts.
• Compatible with Bakflip MX4 and many tri/quad fold aftermarket covers.
• Top buckles mount to side rails; bottom buckles attach to the bed or cover D‑rings.
• Replaces both top and bottom side fasteners for a complete repair.

What materials are used and how durable are they?

The straps are woven from industrial‑grade polyester webbing for tensile strength and abrasion resistance, while the buckles are molded from reinforced ABS plastic formulated to resist UV, impact and corrosion in outdoor automotive use. These materials were selected to withstand repeated tensioning and exposure to road and weather conditions.

• High‑tensile polyester resists stretching and fraying.
• Reinforced ABS buckles withstand impact and sunlight exposure.
• Corrosion‑resistant hardware included for exterior mounting points.
• Designed for long service under normal driving and storage cycles.

How easy is installation and what tools are needed?

Installation is straightforward and intended for DIY replacement using basic hand tools. The top buckles attach using the existing mounting locations on the truck rails, and the bottom buckles connect to the bed or cover D‑rings; you typically won’t need specialty tools or drilling.

• Usually installs in minutes per side with common hand tools.
• No cutting, drilling, or permanent modifications required.
• Includes all mounting hardware needed to replace both sides.
• Clear swap‑out process for anyone comfortable with basic vehicle fasteners.

Will this kit keep my tonneau cover secure at highway speeds?

Yes — the assembled buckles and straps maintain cover tension and reduce movement that causes noise and misalignment. When installed correctly, the system locks the cover to the bed and rails to minimize shifting and maintain the intended fit while driving.

• Straps hold tension to prevent cover vibration and noise.
• Buckles lock firmly to keep the cover secured under load.
• Designed to meet the function of factory fasteners at highway speeds.
• Completing both top and bottom replacements restores balanced clamping force.

Who this is for: drivers who own a Bakflip MX4 or a compatible tri/quad‑fold tonneau cover and need a reliable, OEM‑style repair kit for worn or broken D‑ring buckles and straps. It’s ideal for truck owners who want a fast, affordable DIY replacement that restores factory fit and keeps the cover secure without altering factory mounting points.
