Riffraff Diesel 7.3L Powerstroke Injector Cup / Sleeve Tool Set 94-03

Brand New Patented Design!

We have refined our injector cup/sleeve tools over the last 7 years using them as rental units, in the shop and we have now been awarded patents on their design and released them in production.  These tools were designed for 7.3L gear-heads by 7.3L gear-heads.  

Unlike other's cup tools on the market our design is engineered towards repeated shop use, and efficiently removing and installing the injector cups .  We believe removing and installing the injector cups should be a surgical operation, not something requiring beating cups in with hammers and leaving brass filings from removing. This is why we have designed our tools with tight clearances, and clean injector bores in mind.

Since we utilize the latest in metallurgical and coating technology it allows us to thread our removal tool into the damaged injector cup without creating any filings or chips to fall into your cylinders.  Both our puller and installing tool use bridges that are quickly fastened to the injector mounting holes. This means you don't have to remove your rocker arms allowing for a faster overall job. 

The 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 some 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.

All hardware has been coated for rust resistance as well as a rockwell hardness of over 62 to ensure a long life.

    Injector Cup Remover/Installer

    Posted by Kevin Settle on Jul 11th 2020

    This tool is a must have! I only rented the tool for swapping my cups, but I’m tempted to buy the tool just to have if I ever need it again. This tool basically makes removal and installation of the cups idiot proof.

    The tool works flawlessly. I had never done cups before so I was a little nervous, but this made it a breeze. If you follow the included instructions, they’re basically no way to mess it up. I’d give this more than 5 stars if I could!! Highly recommended!

    Injector Removal Tool

    Posted by Cam Bubp on Jun 8th 2020

    This tool is worth its weigh its weight in gold. I cheaped out and bought an ebay tool at first and tried it on the first cup and instantly regretted it. Ordered the riffraff cup tool right after and had it next day air shipped to me and i was impressed. The tool worked great and did not create shavings as my cheaper tool. I bought it instead of renting because my family owns numerous 7.3s and international trucks. Always satisfied with my riffraff purchases, thanks clay!

    Amazing improvements

    Posted by Mike on May 24th 2020

    I had the Rosewood tools. I no longer have them. These are so far superior to the old Rosewood tools (granted they were a great innovation when they came out), that I will never need the old ones again. These make the job SO much easier and FASTER. But they biggest advantage/plus to these tools is they ensure SUCCESS on the cup jobs on the first try EVERY TIME. As a mobile mechanic, that is crucial. I let the cups cure WITHOUT the injectors in the bores for 24 hours before throwing everything back together. These are worth twice the price.

    Great tool! Easier to use than the shop's set and I think it does a better job also. I am very glad I brought this one.

    Best Tool - Period

    Posted by Dan Jenkins on Mar 29th 2020

    I rented this tool last year to do injector cups on my dads 2002 and it worked perfect, and made quick work of an other wise PIA job. Fast forward to this year, my 1999 needs cups and I knew right where to go. But this time I decided to purchase it because it is just such a well made, easy to use tool. Thank you Riffraff Diesel for always innovating for these trucks, and producing such a great product.

    There's no better tool made for this job. It worked perfectly every time. Even in the hard to reach back injectors. I highly recommend it.
