BILLET THERMOSTAT HOUSING
Perfect fit for my 1999 f250 super duty 7.3 power stroke. Looks great. Also replaced the thermostat. Which was perfect timing since the seal on the original was starting to fall apart.

Billet thermostat housing
I bought the Riffraff billet thermostat housing in red for my mom's NBS 7.3l. The fitment is perfect and the red looks sharp!

Nice quality piece, machined to proper specs for tight hose fit and to replace that stamped leaky stocker. Thanks.

Perfect fit and finish
Another high quality American made part by RiffRaff. Clay is a perfectionist and it shows in the parts he sell and makes ! If you still have a sheet metal thermostat housing this billet one is a must do.

Great Upgrade from Factory!
My factory neck was getting pitted and starting to seep coolant, this looks great and sealed everything back up!
