I needed a forklift part and wasn’t sure which one fit. They asked for the model and serial number, got back to me quickly, and made sure I ordered the right one. Really helpful.

Product Overview
The 2X Semi Truck Locking Diesel Fuel Tank Cap Cover replaces standard fuel caps with two keyed-alike locking caps, keeping your diesel secure from theft and contamination. These heavy-duty locking diesel fuel tank caps thread directly onto the filler neck of most Freightliner and Western Star semi-trucks, providing a tight, tamper-resistant seal. Built for long-haul reliability, these semi-truck locking fuel caps give fleet managers and owner-operators peace of mind at every stop.

- Heavy-duty die-cast metal body resists impacts, vibration, and harsh weather
- Corrosion-resistant chrome finish keeps the cap looking new after years of road use
- Vented cap relieves internal tank pressure without leaking fuel or introducing moisture
- Easy hand-tighten installation—no special tools or modifications required
Fitment & Compatibility
- Freightliner Cascadia, Columbia, and Century models

- Preventing fuel theft at overnight parking areas, rest stops, and depots
- Fleet-wide fuel security for logistics and transportation companies
- Replacing worn, missing, or non-locking fuel caps on heavy-duty trucks
Frequently Asked Questions
Q: Do these caps come with keys? A: Yes, the 2-pack includes two locking fuel caps and two matching keys. Both caps are keyed alike, so a single key operates both.
Q: Will these fit my specific Freightliner or Western Star model? A: These caps are designed to fit standard diesel filler necks found on most Freightliner and Western Star semi-trucks. Always verify your tank’s thread size—commonly 3-1/2" NPT—before ordering.
