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.

    No better tool for the job

    I previously had used the standard tool set for 7.3 injector sleeves, hammering the cups in was never confidence-inspiring. This tool set worked like a dream and is one of the best built tools I’ve used to date in my 28 years in the business. Nothing compares!

    This tool worked flawlessly, and I can't imagine going back to having to beat the cups in with the old tooling I have. Kudos for your ingenuity guys and thank you for making this job so much easier!

    7.3 injector cup tool

    Posted by Harry on Mar 25th 2019

    Tool works as it should, quality tool
    Needs a hardened washer or bearing between the steel nut and the aluminum cross bar for the removal tool, I cleaned and oiled the threads and nut after each cup removal and still had aluminum particals from the nut cutting into the aluminum. I did chamfer the outside diameter of the flange nut ever so slightly to remove the sharp edge, it helped some

    Great quality product

    This tool set made it a breeze to remove the old busted cups and install the new ones I purchased from Riffraff. The removal tool took the cup out, it took 7 quarter turns roughly in each cup. The instructions on their website make it too easy to use both tools. Highly recommend to any that find themselves having to replace their injector cups.

    I am a tech and a shop owner. This tool works great. I used it for the #6 and #8 injector cups. Saves so much time, no need to remove the rocker arms or cylinder head. Easy to use, even on the #8 cup right against the firewall. Must have tool for a diesel tech.
