I'm giving this filter kit 5 stars because it deserves it. The block, the lines, the fittings are all better than the competetion, I know because I ran them first. Every one of them leaked. This kit is heavy duty and completely leak free. Not a drop. I recommend this one to all my 7.3 friends because I know it works. That peace of mind means I dont have to check it and check it like I did with the others. This one I can just let roll because I know it works. THE only gripe is shipping. I think they put it on horseback from RR to Atlanta because it took forever. That could have been better, and should have been. Gotta do something about farther reach orders fellas. I've heard that from multiple other buddies that order from RR. Time for a change.

But, you WILL NOT find a better coolant filter assembly. Anywhere. Take some time and install from the water pump out. The non-non swivel fittings are the reason this thing is locked up tight (no drip) and I'm thankful for it. The mount completely replaces the upper radiator mount, it even accepted the OEM rubber insert without issue. High five to whoever thought this out, give that man a raise.

I'll be back for yet another cart full of RR goodies.

I have 2000 7.3 and I love the filter on it. Keeps me calm knowing I don’t have junk in my engine. I just wish they had it for the older trucks.

Very easy to install per the RiffRaff detailed instructions. I am looking forward to the future results to see how well this may clean up my son’s 2000 F250 7.3 Powerstroke coolant system. We bought 2 additional filters and plan to change out the first one 3 months from now. If this works, I plan to purchase 2 more kits for my ‘02 and my early ‘99 Superduty’s.

Great filter set up. You do have to build it in a strategic way due to the non-swiveling hoses. And had to shim the mount so it did not touch the air filter housing. Overall very nice.

The product came well packaged and fit my truck with no issues. Have had no issues with the function of this item.

Really nice to install comes with everything

Great kit everything is high quality. A must for removing silicate fallout and gunk from coolant. Pretty straightforward install. No leaks or issues.

My truck went 240k without any filtration and maybe a handful of flushes in 20 years. Installation was a breeze and after 400 miles on the first filter it was plugged! Crazy how much contamination flows through the cooling system. Buy this kit and make sure to get extra filters, you’ll need em! Worth every penny!

I absolutely love this thing I just installed it on my 7.3 L Powerstroke so I’ll need time before I can see the results but looks so good under the hood. ??
