Thanks for letting us help Shaun. Yes, the Replacement Lens, Gaskets, Lens Retainer, Vent Plug, and Screws # VA85JR will work with your Valcrum ST-400 Series oil caps, as long as they were manufactured after August 2019. The ST-400 Series caps were redesigned around that time to accommodate Lippert and Dexter axle applications, so the manufacturing date is an important factor in determining compatibility. If you're unsure when your caps were manufactured, I'd recommend checking the identification tag on your axle. While it won't necessarily tell us the exact manufacture date of the oil caps, it can give us a good indication of whether you have the newer version.

Are you replacing these components because your existing oil caps are leaking?
