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.

  • USA Made Billet Stainless Steel 
  • 100% Designed and Manufactured in USA

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.

    SS injector cups and installation tool

    Posted by Bjorn on Apr 26th 2021

    Excellent quality product and super fast shipping as always. Being a machinist I checked all of the injector cups with a micrometer before installing and all diameters were within .001 or better of each other and the install was a breeze with the supplied tool. Well worth the money.

    Stainless Steel Injector Cups/Toolset

    Posted by BLind on Apr 21st 2021

    Install went good with the Riffraff tool -- nice to wrench the cup into place rather then sending it with a hammer, and less probability of shavings in your piston cause it bits just enough, although I've heard of others putting a penny down the cup before removing with the tool. If you're gonna have to change these, I would suggest the upgrade -- as it only took 150k for the stock ones to go out and these should last 5x.

    SS Injector Cups

    Posted by Clayton Benoit on Feb 3rd 2021

    Found these to be a much nicer fit/finish then the brass ones, they were smooth, rounded edges, no burs, Felt a bit thicker/sturdier but didn't measure for comparison. Nice product installed easily with the Riff Raff removal/ install tools. Which I also recommend since access to the rear injectors is limited and other tools that require use of a hammer to seat the new cups isn't an option

    Quality Cups, Awesome Tool!

    Posted by Terry Smith on Dec 30th 2020

    The stainless steel cups appeared to be well made. The material seemed to be thicker than the original cups. They seated and sealed perfectly. The Riff Raff injector cup tool is awesome. It made the part of the job I dreaded most (cup r&r) the easiest most painless part of the entire job. It only took about 20 minutes a cup for r&r . Now cleaning each bore properly was another story. Overall very happy with cups and tool!

    I bought 2 sets of factory brass injector cups for 2-7.3L stock engines. Both only made it around 60,000 miles before some cracked again. I know 2 people that installed these well built stainless cups. They both are daily drivers and have a over 130,000 mile of hard abuse with out a single problem. One guy pulls a 3 car hauler. The other guy is pushing well over 500hp. These injector cups look and feel well built. Not all weak made like the brass ones. Don’t understand why Ford and international came up with such a cheap design flaw. When the engines are build so well. Every 7.3.L owner should spend the extra money. Put a set of these bulletproof injector cups. Save the hassle of kelp replacing the crappy made brass ones. People...Do it once, Do it right. Thank you Riffraff diesel making a solid product and solving the problem.
