Great Product
The design of this thermostat housing is a huge upgrade from the stock housing which is to thin and bends when you tighten the bolts down making it a weak point in the cooling system. This housing is much thicker and can be reused if you have to change out a thermostat and you won't have to worry about it leaking.It also has a much cleaner finish than the original.
Great Job as usual Riffraff Diesel! -
Have not installed it yet
If the function of this item is equal to the quality of the material and finish I give it 5 stars. Once installed and I need to update rating I will but for now 5.

Awesome work !
I have a custom truck that has been in one of the popular diesel mags. The stock piece was not only ugly it was a maintanence issue. This is the answer to form and function. No rust ! and a great look

T-Stat housing that takes the cake
This is the best one on the market. Love the feel and weight of it also the nice heavy duty stainless hex head bolts. No leaks!!!

Fantastic Product
Finally upgraded my stock one and this looks like it will last the life time of the truck.

Awesome housing.
Definitely better then the stock rusty steel one.

Perfect fit, excellent product
This is an almost perfect product, the only improvement I can suggest would be to have a groove machined into this and an O-ring that replaces the original thermostat gasket as it can move out of place and leak if not installed very carefully.
