RANSOTO Tailgate Molding Top Trim Cap for Ford F-150 (2015–2020) — ABS Step Edge Protector, UV-Resistant

How is the trim cap made and how long will it last?

The cap is injection-molded from high-quality ABS plastic that balances flexibility and toughness. ABS is chosen for automotive exterior parts because it holds its shape across temperature extremes and resists UV-related discoloration, so you get a long-lasting factory-style finish.

• Material: automotive-grade ABS plastic
• UV and weather resistant for outdoor use
• Formed to match tailgate curvature for even load distribution
• Surface resists minor scratches and fading

How does installation work and what tools are required?

Installation is straightforward and typically requires no cutting. The replacement cap is designed to align with the original mounting points and snap or bolt into place depending on your truck’s configuration. Most owners can complete the swap in under 30 minutes with basic hand tools.

• Pre-aligned for original mounting locations
• May require simple hand tools (screwdriver, trim pry tool)
• No need to reshape — fits factory contour
• Detailed inspection recommended after installation to ensure secure fit

What protection and appearance benefits does this cap provide?

The RANSOTO tailgate trim cap adds a protective barrier at the most exposed edge of the tailgate step, reducing the risk of chips, scuffs and small dents from cargo or foot traffic. It also restores a clean, uniform look when the original piece is worn or missing, improving curb appeal.

• Protects painted tailgate edge from contact damage
• Maintains original tailgate styling and lines
• Works with routine washing and detailing
• Can prevent corrosion by covering exposed substrate

If the product arrives damaged, RANSOTO provides warranty support to replace or repair the item so you can install with confidence. Inspect packaging and part on arrival and contact customer service promptly for any issues.
