Our Patented Injector Cup/Sleeve Tool Set for the Ford 7.3L Powerstroke Diesel is the result of 12 years of refinement by 7.3L enthusiasts. 12 years of testing and tweaking until it was absolutely per

Ford’s Dana 50/60 front wheel bearings (1999–2016 Super Duty 4x4) aren’t designed to be regularly serviced or greased—which is a big part of why unit bearings can feel like a “replace, don’t maintain”

If the O/D OFF light on your shifter is flashing, your truck is not just asking for attention. It is telling you the PCM saw a transmission-related fault. A solid light usually means overdrive was man

If you own a 1999–2003 Ford 7.3 Powerstroke, you’ve probably noticed the factory upper radiator hose routing is not the greatest. On late ’99–’03 trucks, the stock hose snakes through the serpentine b

If you’re hunting a replacement front wheel bearing/hub assembly for a 1999–2004 Ford F-250/F-350 4WD, the first thing that matters is stud thread pitch. This Axiom unit is specifically for coarse thr

If you tow with a 1999–2003 7.3L Super Duty, you already know the weak link isn’t usually the engine—it’s usually 4R100 transmission heat issues. That’s where the Gradient Transmission Cooler (GC-TRAN

The 7.3 Powerstroke exhaust back pressure tube connects the passenger-side exhaust manifold to the EBP sensor mounted near the front of the HPOP reservoir. That tube lets the sensor read exhaust press

Outside the completely fixable issues we all know about that have given it a bad reputation (oil cooler failures, EGR issues, turbo failures, head gasket issues) the 6.0L Powerstroke is known for its

The factory 6.0L Powerstroke EGR cooler is a common failure point, especially when the oil cooler plugs and restricts coolant flow to the EGR cooler. When that happens, owners may see coolant loss, wh

If your 7.3 Powerstroke has ever done the turkey gobble / flutter thing under load, you’ve met compressor surge. In laymans terms, surge is teh turbo becoming innefficient/pushed too far for its desig

7.3L Powerstroke owners have always been ridiculed for marking their territory (i.e., leaking oil, leaving spots wherever they park). We’re going to plead the Fifth on the validity of that statement,

Riffraff is a term for the common people, or hoi polloi. The term is derived from Old French “rif et raf” meaning "one and all, every bit."

If you own a 1994–2000 7.3L Powerstroke, you’re likely missing the benefit of the low-pressure oil mesh screen found on later 2001–2003 models. Most don't understand that the HPOP takes it's supply di

The 7.3 Powerstroke HPOP reservoir feeds oil to the high-pressure oil system. When the factory cast reservoir cracks, leaks, or has damaged threads, it can create oil leaks in the valley and make diag

A big part of diagnosing issues with any engine is knowing how each system works. Electrical can freak people out because you can’t see it doing its thing. That’s usually the whole problem. So let’s m

A 7.3 Powerstroke thermostat housing leak often starts small—coolant smell, dried residue near the upper hose, or a slow drip that usually only shows up after a heat cycle. On 1999–2003 7.3L trucks, a

The 7.3L Powerstroke is one of the most reliable diesel engines ever built, but as these engines get older, many issues become more and more common. Hard starts being near the top of that list. But th

Injector cups are one of those 7.3 jobs where the tool matters as much as the parts. You’re working right over an open cylinder, and the old-school methods (big taps + slide hammers, or hammering cups

The factory 7.3 Powerstroke valve covers do their job, but they are still thin stamped covers on a 20+ year old truck. When sealing matters, rigidity matters. That’s why we built the Riffraff Diesel B
