KYNTHAX Rear Seat Release Kit for Ford F-150/F-250/F-350/F-450 2009–2025 — Black Cast Steel Direct-Fit

The KYNTHAX Rear Seat Release Kit is a direct-fit OEM replacement latch that gives fast, reliable access to the hidden storage behind rear seats in Ford F-150, F-250, F-350 and F-450 trucks (2009–2025).

If your factory rear seat release is broken, hard to reach, or missing, this one-piece KYNTHAX unit restores seamless seat folding and reveals the under-seat storage used for tools, jumper cables, or valuables. Made to replace original part numbers FU5Z-9661383-C and AL3Z-9661383-A, the kit mirrors factory fitment and reuses the stock mounting hardware so installation is clean and reversible.

How durable is the KYNTHAX latch compared with the original?

The KYNTHAX assembly is built as a single, heavy-duty unit designed to avoid the weak joints and add-on brackets common with aftermarket fixes. Its cast steel body and rust-resistant finish resist corrosion while the polyester strap delivers abrasion resistance for repeated pulls.

• Cast steel body with black corrosion-resistant coating.
• 0.7-inch-wide polyester strap engineered for longevity.
• No separate brackets or multi-piece assemblies—single robust unit.
• Designed to withstand frequent use without stretching or loosening.

Is installation difficult and will it damage my interior?

Installation is simple and non-invasive: the kit reuses the factory two screws for a straightforward swap that does not require drilling or trimming. Most users complete the replacement in about five minutes and restore full seat-lock functionality by pushing the seat back until it clicks.

• Reuses factory mounting points and screws—no drilling required.
• Quick 5-minute swap with common hand tools.
• Instructions: remove old latch, install new unit, push seat back until it locks.
• No adhesive or cutting—original interior integrity preserved.

What practical benefits does this unlock for daily use?

One clean pull opens the rear seat to reveal a concealed storage space ideal for storing items you want out of sight. That instant access makes the KYNTHAX kit useful for everyday needs where convenience and security matter.

• Fast access to under-seat storage for tools and emergency gear.
• Keeps valuables out of plain view for improved security.
• Reliable operation reduces frustration from broken or hard-to-reach latches.
• Maintains factory appearance with a matte black finish.
