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.

    Awesome Cups and Tool!

    Posted by Kevin on Sep 23rd 2023

    I echo all the reviews, excellent quality and rental tool quality and ease of use! This was my first time changing cups everything went smooth. I was surprised how tight the cups pressed in, glad to have this tool can't imaging having to hammer them in. Awesome!

    Best on the Market

    This is the only cups you should even be considering. The quality and engineering is amazing. When I purchased I noticed it says they are patented and I didn't get why bother, but now I see. These are a work of art and fit perfectly into my 2001 7.3 F350. I highly recommend using the Riffraff Diesel tool as well. Makes it a seamless and simple job.

    Quality you can see

    Posted by Kyle Patterson on Jul 25th 2023

    Lets start from the beginning, Quick shipping, well packaged box, cups come individually separated in a custom box and very well protected. Not to mention they are so well machined. Install was a breeze with the Riffraff rental tool. They emailed a label for rental tool return and was refunded the day it was delivered back to them. Cant ask for a better product or better customer service. These guys are doing it right!

    Solid Quality

    Posted by Jack Chandler on Feb 16th 2023

    You really can't understand the quality of these cups until you have them in your hand. They come very nicely packaged, and the machining is on par with the next I have seen. Riffraff Diesel has taken a critical part of your engine to the next level in engineering and quality. From what I see that have made brass cups obsolete with their innovative engineering.

    Nicely made, tight fit.

    250k + miles. This is the 3rd cup change by an original owner. Did not leak test before assembly. I wanted the injectors in ASAP in case there was any cup movement. Job went very well. Get a pneumatic nail driver instead of swinging a hammer.

    Injector cups

    So far so good, seem to be a definite improvement over original brass design. Riffraff tool kit was a breeze for remove and replacement.

    Excellent Quality

    Really this isnt even a choice. When you see the quality of these billet stainless cups you will know why they have so many reviews. When I started looking I wasnt sure, but now that I have them in hand and have installed them I can tell you they are well made and an excellent choice.
