    Awesome product

    Posted by Logan H on Apr 3rd 2024

    Pairs great with the thermostat housing, it’s a solid piece of Al that should last the life of the truck. Very happy RiffRaff continues to take the time to design and sell these types of products.

    Thanks RiffRaff

    Water pump billet outlet

    Posted by Scott McBride on Mar 1st 2023

    As expected another great piece of machining from Riffraff. I had to replace my water pump and already had the billet inlet and that is a great piece so I knew this would be just as good.

    I recommend this product for the ease of use. The oem steel outlet had rusted and I almost had to cut the hose off. The top hose I was able to twist off because I already had the billet inlet.

    They look great and work even better.!

    I was replacing the water pump on my truck and the original thermostat housing and straight lower inlet had seen better days 149k miles ago. They were rusty and crusty. I had ordered from Riff Raff before so ordering their billet thermostat housing and billet lower straight inlet was the plan when replacing the pump. Thank you Riff Raff for carrying Motorcraft products and quality Riff Raff products. Also excellent customer service when I have questions.
    Thank you.

    Tougher than stock

    Posted by Randy on Nov 14th 2022

    These are the best deal going! Stronger and thicker than stock, won't rust and look amazing. Best of all they are cheaper than the factory motorcraft replacement part.
