5R110W Sprag Clutch, new and ready to install. Fits the 5R110W. Ships fast from the USA.
This listing is a complete Raybestos RGPZ-5110 friction clutch pack for the 2005-2007 Ford 5R110W TorqShift, the five-speed automatic behind the 6.0L Power Stroke and the 5.4L and 6.8L gas engines in Super Duty pickups, cab-and-chassis trucks and the Excursion. It is filed under our sprag clutch heading, but it is not a one-way clutch: it is the full set of lined friction plates for every clutch pack in the unit, built from Raybestos GPZ material with Stage-1 plates in the coast and low/reverse positions. If your truck slips under load, flares between gears while towing, or came back from a hot pull with burnt fluid, this is the friction half of the rebuild.
The 5R110W is a redesign of the 4R100 with an overdrive section added up front. Ford's solenoid body gives each clutch pack its own solenoid and pressure switch, except the forward clutch, which is fed by the manual valve. That means a slipping pack shows up as a specific gear problem rather than a general sag. Second gear, for example, is first gear with the overdrive clutch applied, so a worn overdrive pack shows up as a flare or slip on the 1-2 shift. The pack is made up of these plates:
GPZ is Raybestos's high-energy material for heavy-duty and commercial use, so this pack is aimed at trucks that tow, haul or run added power, not just a stock refresh.
A 5R110W can feel like it is slipping when the real fault is a weak solenoid or a sticking valve, and the clutches are fine. Pull codes and watch commanded versus actual gear on a scan tool first. If the apply-time codes follow one clutch and the solenoid checks out, the friction pack is the next suspect. Our 5R110 rebuild guide to known wear points covers the coast-clutch, low/reverse and planetary updates you should inspect while the case is open, and the 5R110 solenoid testing guide helps rule out the electrical side.
Raybestos catalogs RGPZ-5110 for 2005-2007 5R110W units. The year cutoff is real. In 2005 Ford changed the front planetary and the forward clutch, and the forward friction spline went from 90 teeth to 76 teeth, so 2003-2004 frictions do not interchange with 2005-up units. At the other end, late-2008 production attached the low one-way clutch to the rear planet with the low/reverse plates built into that assembly. Also note that 5.4L gas units use a five-plate low/reverse pack while the 6.8L and diesel use six, so you may have spare plates. To be sure, count the teeth on an old forward friction or send us your year and VIN before ordering. Browse the rest of the 5R110W parts collection for matching hard parts.
If your truck is stock and mostly runs empty, the lower-cost Raybestos HT friction pack for 2005-2007 is the OE-style alternative.

No. Despite the listing name, this is the Raybestos RGPZ-5110 friction clutch pack: the lined friction plates for the overdrive, coast, forward, direct, intermediate and low/reverse clutches. It does not include the overdrive or low one-way clutch, steels, seals or gaskets.
No. RGPZ-5110 is cataloged for 2005-2007. Ford changed the forward clutch in 2005, going from 90-tooth to 76-tooth frictions, so the early units need a different pack. Send us your year and VIN if you are not sure which unit you have.
The pack carries 6 standard low/reverse plates and 6 Stage-1 red low/reverse plates, so the builder can choose the material for the application. Diesel and 6.8L units use a six-plate low/reverse pack, while the 5.4L gas unit uses five.
Mercon SP. Ford specifies it for the 5R110W and warns that other fluids can cause abnormal operation. Soak the new frictions in the same fluid before assembly.
Plan on an overhaul kit for seals and gaskets, new steels if the old ones are heat-marked, a new filter, and the updated low/reverse retaining ring. After the rebuild, clear codes and let the computer relearn shifts with a gentle drive cycle before towing.
