Rear discs upgrade on 1st gen dually??

["Mad Max"]

Dana 70, 3:54 posi, ABS, dually, w/ disc brakes..... how, how, how?



So I'm planning my dually conversion and researching possibilities, and I need to know if there is a conversion/swap/kit out there either a stock parts swap or in the after market that removes the drums on a 1st gen dually rear and replaces with discs that also includes parking prake?



Or, is there any reason that a 2nd gen D70 dually rear with the factory discs won't work under a 1st gen rig? What years have the discs? Rig is getting custom suspension so keeping the axle attached to the frame is covered. I need the posi, ABS, dually, w/ 3:54's, w/ discs.



It will happen, and I know it has either been done or thought about - so I need yer help dudes - How do I do it?

Sam,



Here goes with what I know about rear discs on a 1st gen dually. You can use a conversion kit like EGR, for example, if you install 19. 5" wheels. You can't use rear discs on the original D70 and 16" wheels, there is a clearance problem. Unfortunately, I can't answer any of your questions about the 2nd gen D80 with discs on. Hope this helps.

So you'ew telling me I cant get a rear disk conversion for my 91 dually? That blows. I hate having the drums, or rather, the self adjusting (crawl under and adjust it yerself) brakes, along with the ABS valve that sometimes allows the pressure to get to the wheel cylinders, and sometimes not. At least they make rear shoes.
