Hey all i just ordered the James duff 3.5in Monster Suspension system a few days ago. I have a 1970 Bronco with cut fenders and flares. It has a 2 in body lift and a brand spanking new set of 33x12.5 R15 BFG KM2 Mud terrains. Are these going to be too small for the amount of lift and flex im going to have? If so 35" or 36" diameter?? Please post pics Duff lift or not of your broncos with 3.5 suspension lift and 2 body lift! Thanks a lot!

I ran 35's for years with no problems at all......I would suggest though to not install the drop trac arm and order the duff riser or the WH riser....I have all duff but I have the WH riser......I have ripped the drop bracket off the frame 3 times....plus the riser gave me a good spot to put some tabs on for my ram

3.5" SL, 2" BL and 32" tires

Here are some pics of mine with Duff 3.5" sl, 2" bl and 32" A/T tires. I agree with Addicted, it needs a little more tire and a little less lift. If I had the energy to do it, I would have pulled the body lift off a long time ago. 35" would probably be the ideal choice. I find that the 3.5" sl w/o the body lift and 33's has a good look to it.

I would put the 33s on it and test out your travel. The 33s might look small but if you get a lot of flex 35s might rub.

You can run 37" tires with 5.5" of lift and cut fenders. Nyles and Kyle.Malone both run that size combination. Speaking of NYLES, has anyone heard from him lately?
