Add rear disk brakes to nnbs anybody?

I'm sure you guys know they really underbraked these trucks. Running 150+ does not help the situation. I have upgraded my front rotors and added Hawk Super Duty pads and it has helped. So what does it take to go disk on the rear? Short of swaping axles could a guy get a different backing plate off of a Tahoe or Subby and use there rotors and Calipers with a proportion valve? Anybody thought about this? I also need a tune and ditch my stupid Predator but would much perfer a dyno tune over a mail order.My Vette tuner (Quality Motorsports) does not jack with pickups so I'm wondering could I get a mail tune and have it adjusted in San Antonio later? I'm in the Dfdub.

Let me know!

Yes, you can do that with the NP tunes.

Sweet what about the brakes? Somebody?

ive always wondered if the obs rearend will fit on the nbs or even off a tahoe or denali

Bump I would be shocked if anybody has not looked into this.I dont want to spend nearlly 1k at ssbc if I can use factory parts for less!

he would have to use a 99-04 cause in 05 they went to the drum setup.

There is some 07+ trucks with disc rears

yea he said sumthimg like that,,but hes done it before on a 90 chevy,,he put a rearend off a 2000.now on hes gonna do it to his 08'.cause damm drums look nasty

All the 6.0 and 6.2 trucks have them. It is like a 75 dollar option on the other trucks. My 2005 had them. I never even considered they would go back to drums a week later I noticed. I would perfer to keep my axle and change backing plate out. Anybody know anyone who works at a dealer and could check part numbers I need the stopping power!

Nathan, (GasGuzzler) im sure could help you out

Only 2500+ trucks 05+ have discs on the back. This does not count utilities that are all disc. Not worth the effort although the discs are much better IMO. I'm not considering specialty models BTW.

there are companies that buy surplus parts from axle mfg companies and sell them for about $500 complete. I think Cowl327 or Txarkitkt knew of a place in DFW to get them.

you can buy weld on brackets for the calipers for under 90bucks. and you can bolt on calipers and rotors on the back. Use a search on ebay and you should find some.

Rob--There are brackets (as stated above) where you can adapt the trucks for rear discs. Just grab a set from the salvage yard from a How Or Sub and you're in business. It sounds like you are on the right track as far as things go, so yes--the proportioning valve is definitely required.
