Good To Know
Q: Will these locking caps fit all Freightliner and Western Star models? A: They are designed for standard diesel filler necks found on most Freightliner and Western Star semi trucks, but verifying your tank opening diameter ensures a proper fit.
Q: Do both caps use the same key? A: Yes, the caps are keyed alike so a single key operates both, simplifying daily use and reducing the number of keys to manage.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
