I'm building a D 50 to go under a 84 F 150 so I thought I would pass along some information some might find useful.

I've been working with RCV and they will now offer their CM CV axles for D 50 TTBs. I provided them with a new Spicer D 50 outer stub and they have done the engineering to match it to their D 44 TTB axle set. There will be a small upcharge for the D 50 outers. I'm waiting for a part number to reference. As soon as I have it I'll post here. We have not discussed any difference in inner shaft lengths so be sure you have exact lengths if you go this way.

Next there are forged, heat treated CM D 50 spindles available here:https://torqueking.com/product/8820227/ ... s-spindle/ .

New 5 X 5.5 lug pattern D 50 hubs are available from Six States. Some years ago they had a bunch made but they didn't advertise and they have been collecting dust on the shelf. As of a month ago they had 11 left. If anyone is interested I can get the part number.

I am a big fan of this info. I would be interested in all part numbers.

Might be interested in the 5x5.5 hubs. That’s interesting.

Part number for hubs ?

SS7006-5
list is about $200. But if you squeeze a little you can get them cheaper because they are basically dead stock.

Note that these are 93 and down. The 94+ uses a different rotor mount pattern.

Once you get the 5x5.5 hubs where do you get rotors then? Or how do you go about getting rotors to work?

I am using custom Coleman billet hats and 14" rotors with CNC 6 piston calipers. Use the 95-97 outer knuckle and it's a simple bolt up with an adapter.

RCV part number for the D50 TTB outer stub is D11627. Talk to Sean Rehberg if you want to go this way.

Because the 95-97 used a bolt on caliper you could use a variety of rotors and bolt on calipers with an adapter plate.

Another tidbit for D50 lovers.

If you want to run a Trutrac or other diff not available for D50's, it's easy peasy.
DTS in Michigan has adapter sleeves that press on a D44 carrier and adapt it to D50 carrier bearings. The ring gear one has a shoulder to move the carrier over for correct alignment. You use a 3.73 down carrier.

Press the sleeves on and set up r&p as usual.
Sleeve set is $120 plus shipping.

At that point why not just run a d44 thirdmember. They should bolt right into the d50 beams and d50 axles will slide in as well. I believe the d44 is close to a 8.8” ring gear and the d50 is around 9”.

D50 r&p is 44% stronger than the D44. Read about the Jana 54. Adapts a D 50 r&p into a D44 to gain the strength.
