Duals for a SRW ???
I have a feeling this may not work, but I haven't found the answer. I have the 2011 SRW and would like to get a set of duals for sled pulling only. I would take them in the back and install at track, therefore I don't care about fenders.
Is the rear end, axle, brake disc, etc the same from a dually?
Looking at them driving down the highway tonight makes me think maybe not?
I just have too much horsepower and torque for my tires, my other option is buying wide rims and really wide tires, which means really high prices!

For your purposes, yes you can add spacers and duals. Your rear is a Sterling 10.5 and the dually rear is Dana 80. They are not the same or even close to being the same. You can't mount regular dually wheels to your truck an expect it to work, but they make spacers for what you want to do.
A lot of sled pullers around here play with the duals thinking it will be a lot better setup. I don't see too many of them stick with it. Finding the right tire for your track conditions and finding the perfect air pressure for those tires is probably the more prudent and especially more economical route.

Thank you thank you!
I knew somebody would know this and there are at least three here right now!!
I am starting to look for some 13-14" wide tires tonight, I would like to put at least 2 on the front. Then of course I have to get 20" rims that are wide enough or actually I can run 18", so the search is on. It would be great to find a full set but my funds are limited for the pulling hobby.
Hmmm, how much can I get for selling a kidney??

You can buy what they call "super singles" and see what happens. They are the semi truck tires where they run 1 big wide tire in place of the traditional duals. If you can find a used pair of rims/tires from a tractor trailer it may be pretty cheap and fitting to your hub may just be a question of an adapter/spacer.
Anyone that installs "alcoas" has whatever adapter you would need.

In my opinion, I don't think you are in a power category to justify duals just yet if you are only running tuning. Don't get me wrong, 6.7s run good tuned. But only being at 450-490hp, I think money and time could be better spent elsewhere on the truck before considering a dual setup (unless you have more stuff done than what your signature reflects).

I tend to side with UGA. Going with larger diameter wheels and tires will mess with your final drive ratio going the wrong way too. I'd prob lean towards getting a real wide 16"-18" wheel tire combo that will really bite and you can get all 4 to stick with the help of a shorter final drive ratio too.

My truck is chasis dyno'd at 500 HP and 1097 TQ at the rear wheels, it actually hit a peak HP of 552 I think it was. I definitely have a traction issue, believe me I've been pulling for 20 years. If I have a well-prepared tacky track then traction is not an issue, unfortunatelty that's not usually the case.
I have 295/60/20 Nitto Terra Grapplers and they do a good job, I would say just as good as the BFG's I have ran. BTW most of the trucks pulling in street stock, work stock and some in 2.6" classes run BFG's. I more agressive tread is actually a bad thing on a pulling track.
No, I'm not going any taller than 35". Mine right now are only 33" tall and 10.5" wide actual tread. I've found a pair of Mickey Thompson tires that are 35 tall and 13.5" wide with tread worn down to only 1/4" left (which is about perfect), so now I'll be looking for a 20" rim that's 10-12" wide depending on what they really need to mount. I'm waiting for the guy to reply to my offer now.
I know about the super singles but I don't know about rims to fit them and mount onto an 8 lug SD. I'll check them out and see how economical I can get that setup.
Thanks for all the info!!

Super singles are way too heavy, way too expensive and don't come in the type tread pattern that you really need. They seem to either come in a straight steering axle type tread or go straight to an extremely aggressive mud type tread. They will also be 37" tall. SS is a huge power killer!

None yet, but I just commented on the guy that did all his mods to the black truck. He got them for 650 bucks so I may be laying down some dough for them.
Right now I don't notice that it's hurting my traction, per se, but they will probably help my drive shaft and rear springs last longer.
