Billet Thermostat Housing
Very nice product just what you expect from RiffRaff

Happy
I would suggest a gasket come with it
-
Great fit
Worked great it’s a nice well built piece only down side I would say is it doesn’t come with a gasket so if you plan on changing your out make sure you buy a gasket as well

Get This And Forget the Leaks
Works perfectly. Zero leaks is exactly what I wanted after fighting the stamped units for a while. This is the long term fix. Plus it looks great.

Best Quality Thermostat Housing
I had tried one off Amazon, and one from Sinister Diesel, both leaked. This one from Riffraff Diesel is by far the best, and stopped my leak permanently. Quality and machining is also the best I have seen. Stainless hardware is also a very nice tough.

Fit
Would have been nice if it came with a new o-ring.
-
Nice and solid
Nicely constructed and much more solid than the stock piece.
