Riffraff Diesel Injector Cup Billet Stainless Steel Sleeve Set 7.3L 94-03

Now Offering our PATENTED Precision CNC Machined Stainless Steel Extreme Duty injector cups and are priced as a kit of 8.

Features:

  • CNC Machined for precise quality
  • USA Made Billet Stainless Steel 
  • 100% Designed and Manufactured in USA
  • Thicker wall in weak areas for longer lifespan 
  • Greatly increased durability versus stock brass

With your purchase of the cups, we offer you the option to rent the injector cup puller/installer for $75. The rental fee will be taken from the $499 rental tool deposit paid at checkout, with the remaining deposit refunded upon our receipt of the rental tool in good condition. Simply email us within 30 days when you finish with the tool and we will send you a pre-paid USPS shipping label to return the tool.* 

Our Patented puller allows you to remove the cups without removing the heads or using a slide hammer. Also, by using the tool to grab the cup, you can inspect each cup for damage once it has been removed. Other methods (typically a tap) are likely to damage the cup during the removal process and create shavings that end up in your cylinders. 

Our Patented install tool is really the breakthrough; rather than hammering on your new cups in tight spaces and hoping they are seated, simply use a socket and allow the tool to press the cup in. The tool allows for a completely seated cup every time; no guessing and no hammering, even on the back cylinders or e-series vans. To ensure our install tool doesn't deform your new cup as our competitors tools do, it is machined to engage both the full surface of the cup bottom and the top lip. The tool also features an o-ring as a keeper to allow strategic placement of the cup in the injector bore instead of dropping it in and risking displacement of your sealant. In order to allow the cup to seat without turning in the head, the install tool is engineered to include a ball bearing to prevent cup rotation while being pressed in. 

We also have available for purchase the retaining compound and injector o-rings used by Ford and International when reinstalling the cups. 

*Please note that if the tool is not received back within 30 days from customer receipt, then a $25 late charge will be withheld from you deposit. If tool is not received back within 60 days, you will lose your entire deposit.

    Great quality

    Posted by PETER MOREY on Nov 20th 2024

    I forgot to select the sealant, so wound up using Loctite 620 and the SF 7649 primer (needed for stainless steel). They were a breeze to install and the truck is running incredible now with the cups and Full Force reman injectors.

    So much better quality than the brass. Well packaged and easy install with the Riffraff Diesel cup tool set. Highly recommend upgrading to stainless steel while you are doing the job.

    Injector Cup Billet Stainless Steel Sleeve Set 7.3L 94-03

    Posted by Eric on Jul 29th 2024

    I waited to get some mileage on the truck before reviewing. 3500 miles later I am convinced this was money well spent. Take your time with this operation and thoroughly clean the contact areas. The brushes on this site work well, but you also need to get in there with a pick and (gingerly) remove every bit of debris. I also used two different sized mirrors and a cheap (phone powered) bore-scope from Amazon to verify cleanliness. Use the Riff Raff rental tool to install them and consider upping the torque to 145 ft/lbs. It was my first time doing cups and the installation went smoothly, the important thing is to not be in rush and work methodically.
    Thank you Riff Raff.

    High Quality Stainless Cup Kit

    Posted by David on Jul 2nd 2024

    These surpass the stock brass cups by a mile. I have used them exclusively for the last year and after 5 sets can say they are the best quality you can buy for your 7.3

    Stainless injector cups ...

    Excellent product. When you hold one in your hand next to the old brass cup, you can not only see the difference, you can feel it. Much more substantial.
