These are a great upgrade from stock. they are a perfect fit and thread in without issues. they come with great instructions and took under an hour to do on my truck.

Easy to use great fit.

easy peasy diesel no squizy

Replaced all 4. Great solution to increase fuel flow

Wish I could say I had hard data to prove these make a difference; I dont. But at the end of the day anything that facilitates more fuel flow is worth having, especially at this price point. Pay attention to the torque spec and you wont have leaks or issues.

It is obvious Riffraff has made a slight improvement to these since the photos were taken. The slots are now angled slightly instead of completely in-line with the bolt. They are much nicer to install and torque to spec using a socket rather than a square drive. My only complaint.... dummy me ordered one set when I meant to order two.

Order two sets and take care of both ends of the heads. I ordered another set with my next order of other parts.

This is a nice piece.

The Riffraff banjo bolts are an essential part of every 7.3L Powerstroke build we do. They have always proven to be effective and the quality is incredible

Installed the HPX, FRX, banjo bolts and SS fuel feed lines on my 2001 F250 with 7.3 a couple of weeks ago. Not sure on fuel mileage improvements yet, however, I do think it runs a bit smoother and quieted it down some. This is not my daily driver so haven't even put a full tank of fuel thru it so not alot of feed back at the time.

Made a difference in throttle response. I purchased these banjo bolts with a list of parts (full set of injectors and cups, oil cross over line and intake heater delete kit., and a Hydra Truner). All products from Riff Raff Diesel, well made and a fair pricing. Riff Raff service has been exceptional. For my money, when I need parts for my 7.3L, I am turning to Riff Raff Deisel.
