We offer to rent you the injector cup puller/ installer as well with your purchase of the cups for a $499 deposit.  We charge $75 to rent the tool which will be deducted from your deposit, which also includes a pre-paid return USPS shipping label that we can email you when finished.  

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 are able to 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 make shavings that end up in your cylinders. 

Our Patented install tool is really the break through since rather than trying to hammer on it in tight spaces and hope your cup is seated you simply use a socket and allow it to press the cup in.  This allows for a completely seated cup every time, no guessing, no hammering, even on the back cylinders or e-series vans. To ensure our install tool doesn't deform your new cup, like other competitors tools, we have machined it so that it engages both the full surface of the cup bottom as well as the top lip.  We have put an o-ring on it so you can strategically put your cup in the injector bore instead of dropping it in and hoping your sealant stays intact. In order to allow the cup to seat without turning in the head we have engineered the install tool with a ball bearing so it remains stationary while you turn in the press.

We also have retaining compound and injector orings available for purchase that is used by Ford and International when reinstalling the cups.

Please note that if the tool is not received back by 30 days from customer receipt then there will be a $25 late charge.  If tool is not returned in 60 days you will lose your deposit.

    Longevity and Quality

    Posted by Terry E. on Jul 9th 2021

    I purchased and have been running these stainless injector cups for two years now and over 60,000 miles because I hotshot with my 7.3 F350 dually. Put off doing injectors when I did cups, but they finally have run out of life. While replacing injectors last weekend I inspected the cups and have to say they look just like when I installed them. No cracks, leaks, or imperfections. So glad that I went with these over brass, and I recommend them to anyone doing this job. I am sure that these will last the life of the truck given the quality.

    Perfect fit and finish. The rental tool to remove and install worked flawlessly. I would consider it an absolute must for a professional, easy, and confident install.

    They Look Great

    Posted by Jim on Jun 1st 2021

    I have to say, these Stainless Sleeves/Cups looks absolutely great. I would have to say I feel confident in the workmanship of these over the factory punched brass ones. I do not think these will fail in the life of my truck. As of right now, i give these 5+ stars. I will update as time goes by.

    Quality cups and install made easy with install tool

    Posted by Cory R. on May 13th 2021

    At 229K miles my OBS F250 needed cups though they had not cracked yet. Figured I'd skip the brass cups and go straight to the SS ones to avoid any future issues and with the addition of the rental tool the hardest part was cleaning the bores, the install was made dead simple. The cups fit and finish was top notch and thus far no issues after a bit of heavy towing work. Worth every penny.

    A must have.

    This item is so much better than OEM cups. It just makes sense. Also the tool that riffraff makes to remove and install them is unparalleled in the market. I’ll probably never have to do my injector cups again because of it. This stuff is legit!

    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.
