Felisbieti Diesel Fuel & DEF Caps for 2019–2026 Dodge Ram 1500/2500/3500 — Aluminum Magnetic Anodized

Felisbieti’s aluminum magnetic diesel fuel cap plus DEF cap replaces the factory caps on 2019–2026 Dodge Ram 1500/2500/3500 diesel trucks, offering a corrosion-resistant, magnet-backed holder for secure, convenient refueling.

This pair of precision-machined caps is designed specifically for Dodge Ram diesel models from 2019 through 2026. Machined from aviation-grade aluminum with a hard anodized finish, the caps resist corrosion, deformation and everyday wear while adding a polished, aftermarket look to your truck. The diesel fuel cap integrates a covered neodymium magnet so the cap can quickly attach to the vehicle during refueling, minimizing the chance of losing it; the DEF cap mirrors the same build quality for the selective fluid port.

How does the magnetic feature improve refueling?

The built-in permanent neodymium magnet is housed beneath a protective cover so it won’t scratch paint or weaken from handling. When you remove the diesel cap, the magnet lets you park the cap on a metal surface near the filler without needing a pocket or tray, keeping the cap clean and accessible.

• Powerful magnet retains cap on nearby metal surfaces during fueling
• Magnet is enclosed for paint protection and safe handling
• Reduces risk of cap loss and contamination of the fuel neck

What materials and finish protect the caps from weather and corrosion?

Felisbieti uses aviation-grade aluminum alloy combined with a hard anodized coating to produce a durable outer shell. The anodized surface is engineered to resist oxidation and pitting that commonly affect stock plastic or inferior metal caps.

• Aviation-grade aluminum resists bending and deformation
• Hard anodized finish guards against rust and surface wear
• Precision machining ensures a snug, leak-resistant fit

Will these caps fit my Dodge Ram model and perform reliably?

These caps are made exclusively to fit 2019–2026 Dodge Ram 1500, 2500 and 3500 diesel trucks. The dimensions and sealing surfaces match factory specifications, so installation is straightforward and maintains the intended fuel and DEF system protection.

• Specifically compatible with 2019–2026 Dodge Ram diesel models
• Factory-matching sealing to prevent leaks and ingress of dirt
• Simple hand-installation without tools in most cases

How do these caps change the truck’s appearance and everyday use?

Beyond durability, the anodized aluminum provides a clean, upgraded aesthetic that complements aftermarket and OEM trim. Functionally, the magnetic cap streamlines filling stops by giving you a planned place to set the cap and prevents it from getting misplaced on busy job sites or at gas stations.

• Upgraded metallic look for a more finished fuel area
• Helps keep the filler clean and free from debris during use
• Aesthetic and practical without altering vehicle systems

Who is this for: Felisbieti’s aluminum magnetic diesel fuel cap plus DEF cap is aimed at Dodge Ram owners who drive 2019–2026 diesel 1500/2500/3500 trucks and want a durable, rust-resistant alternative to stock caps with the convenience of a secure magnetic holder.
