Rubber gasket
Do you use the OEM gasket or none?

Nice housing, quick shipping
Product was of good quality and finish. Fit well. Wish standard bolts were used in lieu of hex heads to make it easier to tighten and torque.

Great service
I purchased my first one for my wife's truck. After it came and I say the quality I ordered a another one for my Ford Excursion. If you use a stock OEM Thermostat you do not need any other O-ring's or gaskets. The OEM Thermostat has the rubber O-ring built into it. Great product. No leaks.

Excellent Quality
After purchasing and installing this piece I really cannot grasp why anyone would purchase or reuse the low quality stamped steel version. This billet housing is far more superior quality, bolts right up, and looks great.

High Quality
Best replacement for the stock steel thermostat housing that will eventually leak. It's even better that they throw in stainless hardware.

Another awesome product by RiffRaff
Great quality. Thicker than oem and works great. I’ve had it in my truck now for about 600 miles and no leaks and looks great!

Great Quality!
Great product! Way better than OEM housing! I changed my thermostat housing when I replaced my water pump and it fits great, no leaks!
