We offer to rent you the injector cup puller/ installer as well with your purchase of the cups for a $499 deposit.  We charge $50 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 40 days you will loose your deposit.

    Amazing Quality

    Great set of cups. You can really see the difference in the billet stainless quality. Easy install with the rental tool, so I would recommend taking that option as well.

    My advice: change over to stainless injector cups

    Watch this video before you install these cups. These cups appear to be amazing quality, but installing them is more difficult than installing brass cups. Brass cracks, and leaks diesel into your coolant! Ask me how I know this.... Cummins has gone over to stainless, so my guess is stainless is a massive improvement for your 7.3L. Good luck!

    Quality Innovation

    Posted by Larry on Jul 27th 2019

    Never seen these before or heard of Riff raff, but after researching it was a no brainer to upgrade from the brass. I bought both the stainless from riffraff and the brass from my local dealer, but returned the brass after seeing the quality and bulk of these innovative pieces. Rather easy install with the supplied rental tool and couldn't pass it up for only $50. I will be coming back after such a great experience!
