the reason nobody responded to the inquiry about the carbon shaft is probably because nobody is stupid enough to pay $1200 for something that is actually heavier than the aluminum versions and has never been tested in any 05-up at that level of power. to my knowledge there aren't any 3V making 1200hp and i highly doubt any driveshaft that has the required slip joint will tolerate 1200hp. prostocks use a conventional style shaft and their carbon shafts sometimes only last three runs. oh and they are 1000lbs. lighter also.
carbon shaft=over priced & overkill+ increased weight vs. aluminum.

Can the oem pinion flange be modified to fit the rangers' driveshaft?

Ok, so no issues with cutting it and putting on the cobra pinion flange? Just called a shop, and they said if it was tapered, there might be a problem? But from what I've been reading on this forum and others, there hasn't been any issues.

Here's an email I got from Chuck at CHE about using the Ranger drive shaft and Cobra flange:
"Thank you for the info on the driveshaft. We are familiar with the ranger driveshaft.
The thing that sets the PHA driveshaft apart from the rest is that it is a true bolt in using the stock pinion flange. Whenever you replace a pinion flange, the entire rear end should technically be removed to ensure that the pinion pre-load is correct and that the pinion crush sleeve is properly engaged.
We feel that the failure to tear down and re-install the ring and pinion with a new crush sleeve on the pinion when changing the pinion flange creates high potential for driveline vibration or failure. A difference of only a few thousands of an inch on the pinion flanges will make a very large difference in pinion pre-load, and this pre-load can only be measured with the ring gear out of the vehicle. The ring gear can only be removed after the axles and differential are removed.
The PHA driveshaft is a true bolt in that can be accomplished by anybody with common hand tools in their driveway. The ranger driveshaft with the pinion flange is a job that requires specialized tools and a complete tear down of the rear end."
Thank you again for the information,
Chuck

Well, this is very interesting. Glad I haven't ordered the ranger setup yet.

Me too! Looks like when you remove the factory collar the crush ring has to be replaced. Or you could have vibration or worst long term according to Chuck. Sounds like he knows what he is talking about.

he is also trying to sell you something that costs a lot more. he needs to justify his price. i along with about 3 other people have replaced our driveshafts and companion flange with zero vibration/noise or pinion bearing failure. it is absolutely crazy to disassemble a complete differential to measure pinion bearing preload. this is almost always done during the final stage of assembly. i have setup hundreds of rears and replaced countless yokes and companion flanges/pinion seals without tearing apart a perfectly good differential. evidently they aren't mechanics
guys,do what you want. it's your money, but i know what worked for me.

I agree with you but was just passing along the info that CHE sent me. Looks like if you torque the nut back to the same specs the crush ring would remaing the same.
If there were flanges available I might go ahead and try the Ranger shaft.

Order a FORD 03-04 Cobra pinion flange.......I know the FRPP ones are on backorder.....I think it cost 7 bucks more than the FRPP one. They are the exact same pieces except the FORD one comes with a warranty.
