    Just like you would expect, Riffraff takes it to the next level of quality and engineering. Great part, looks amazing and fit was perfect. Stainless hardware is a very nice touch.

    Great product. Very thick aluminum. Uses an o ring seal that is much better design than stock.

    This part is impressive in its design and engineering. Beautifully machined, and surprisingly more stout and rigid than any other I have seen. I bought it for my new engine build because of the color options, but now after installing it I would strongly recommend it base solely on the quality and how much better it is over stock. Doesn't bend, like others I have had.

    Perfect fit looks great like the o ring versus trying to get the cover with sealant on it in position. Works great

    I gotta say this little GEM is awesome and very well thought out. Luckily I've never had to replace one or re seal the stock one and I haven't had the chance to put this one on yet. I'm currently just waiting on my Adrenaline pump to get in and I'll do it all at once and be done with it. Very nice piece though I have no doubt it'll do the job without worrying about it breaking or bending and causing a huge headache.

    Very nice upgrade

    Posted by Cody on May 3rd 2021

    I contemplated on getting this or not but now im glad i did. Very easy install and better than the oem plate. No more rvt when removing or installing as this cover comes with a high quality o-ring. I’ve had it on for about 3weeks now and no leaks. It not only looks great but its a very stout machined piece, much better than the flimsy factory cover that i bent.

    All I can say is it is almost to pretty to put on my truck. The machining is top notch, and it is so nice not to deal with more RTV silicone next time I pull my HPOP to upgrade. Home run guys and the stainless hardware is a very cool addition.
