The good: excellent machining, excellent coating, the stainless hex socket bolts are magnetic so that they can be retrieved from the engine valley with a magnet.

The lip to the hose could have more of a chamfer to ease insertion into the hose-- more functional but perhaps less pretty sitting on a shelf.

Pump has to be replaced (again) in a few weeks, see what the housing looks like then.

I was very pleased with the quality of the part. the machining and finish were perfect. Also the fact that it came with high quality SS allen head bolts that recessed into the thermostat housing is what sets RiffRaff's thermostat housing as the best on the market.

Great machined piece. Installed it along with around the belt radiator hose and new belt with newt stat

Was tired of replacing stamped steel ones when they rusted so I switched to the billet and it fit great plus the inset allen bolts are a good look

Installed this along with new water pump and hoses ...... All from riffraff.
The quality is top notch! Fit is perfect!

Used a new OEM neck when I did my coolant change - still weeped coolant even though I was careful. Replaced it with this unit - it looks good but more importantly it works! I should just have bought it first and eliminated all problems.

High quality part, perfect fit, and added stainless hardware. This fixed a small leak on my truck, looks great, and can be reused next time I change out the thermostat. Get one!

This is an awesome product at a great price, installed this along with an array of other parts from Riffraff. Loved the fact it came with replacement bolts.

I recently changed my coolant and upper radiator hose, and installed this billet housing to mitigate the leaks often experienced with the OEM stamped steel housing.

I am very pleased with the quality of the thermostat housing. Stainless fasteners were a nice touch! I feel if you included a quality thermostat gasket with this housing, it would add value to your customers and clearly set you appart in the competitve online marketplace. I searched and noticed you couldn't even order the gasket separately on your webiste. Not a deal breaker as I purchased it from my local parts house, however if it would have arrived with the thermostat housing, it would have saved me a trip and made my repair that much more efficient.

Packaging was excellent and shipping was fast and reasonably priced. A+

Including the gasket would push my rating up to 5 stars..
