Stainless Steel HPX - Ford 7.3L Powerstroke (94-97)

The Stainless Steel High Pressure Crossover is meant to allow excess oil pressure to flow between both heads allowing for better supply to the injectors. By allowing the oil to flow to the opposite head, the issue of pressure spikes are less and allow for a smoother idle. We manufacture our own SS HPX lines right here in the USA unlike many companies today that outsource their product lines.

  1. Too Easy 5 Star Review

    Posted by on Aug 27th 2018

    This upgrade dropped right in. I didnt have to remove anything from the truck to install and it only took about 10 minutes.

    Perfect fit. Well made. No leaks. Quiet down engine a little or aleast it idles smoother. Looking forward to get fuel crossover as well.

  3. GREAT BUY 5 Star Review

    Posted by on May 7th 2018

    I purchased a 97 7.3 last two years ago for cheap and have done some minor repairs since including new injectors. With 290,000 miles on the truck it was obviously time. After replacing the injectors i still had a moderate 'cackle' at idle and rough idling, after thinking really hard and some extensive research and reading mixed reviews i decided to give the HPX a try, needless to say the results blew me out of the water and my rough idling and cackling has dissappeared, I also noticed better throttle response and slightly easier shifting. Great prouduct for the money and would recommend to everyone, riff raff has never let me down.

    Installed in minutes, perfect fit, and it really quieted down the engine at idle and working! Would definitely recommend this product to everyone!

    Perfect fit, smoother idle, 2 decibels quieter. I would buy not for performance but longevity on your motor

  8. HDX CROSSOVER 5 Star Review

    Posted by on Feb 23rd 2018

    Fast shipment easy install performance as promised will be ordering more items from riffraff. Highly recommend product and vendor

  9. Excellent quality part 5 Star Review

    Posted by on Feb 7th 2018

    Excellent product, exact fit easy install. I’ve made my own (2 other 7.3s) using flexible hydraulic high pressure line but this product is superior in that it takes less room and is easy to install.

  10. Very pleased 5 Star Review

    Posted by on Feb 5th 2018

    Install went very smoothly, did it in about 15 minutes after work. Off idle performance seems a little better. Most definitely a lot quieter which is the main reason I purchased this product. Idle is smoother and quieter and much less engine noise at cruising speeds. Highly recommended.
