The factory housing tends to rust and leak after many years exposed to the elements. This housing is much better and has a beautiful finish on it preventing corrosion. The fit is perfect and it looks good too. If your housing is leaking this is the best option when replacing it.

Replaced all my cooling components when my water pump blew and while I had it apart, I wanted to spruce up the engine bay with this T-stat housing. It gives me much more confidence than the factory 300k mile steel housing.

Perfect fit and hardware. Dresses up that ol 7.3.

Pretty clean little set up, built way better then stock thermostat housing

Very happy with the thermostat housing. Well-made and looks great!

I got the billet thermostat housing for my 2003 F250 7.3L since the original started rusting. It looks great, fits great, and appears to be very good quality. Looking forward to getting more Riff Raff Diesel parts!

The stock bolts stripped out on me so i had to cut them out. clean product and a good company shipped the same day i think

Far superior to another brand billet housing that I ran for years.

Very nice product just what you expect from RiffRaff
