You can drill and tap your bump stops and screw a bolt in to make them adjustable.
Unless you remove some of the metal of the bump stop before you drill and install an adjustable bolt, the head of the bolt will be the same thickness as the nut welded to the bump stop. A lot of extra work for same outcome. The adjustment will allow you to make the gap between the spring and the tire greater but not smaller once stock tires are re-installed.
i know i am digging up a fairly old thread but i have been searching for answers and this has just about answered my question but just to make sure. i am going to ad a 2.5 leveling kit and found 35s mounted on 18x9 wheels with 4.53" backspacing. will they work?
Those will stick out pretty far and might rub your fender/bumper. Since you have an '05 you should be looking for a tire with 5-5.5" backspace on a 9" wide wheel. That wheel is about perfect for an '04 and earlier truck.
That should fit very well for you then. I have 18x10 wheels with 5" backspace on my '03 and with 35x12.50" tires the tread is about 1/4" outside the fender and at full lock they are 3/4" from the leaf springs. So with a 9" wheel you could actually get away with 5" backspace and they would be tucked under the fender and go within 1/4" of the leaf springs at full lock.
Iím new here and Iím a newbie with trucks. I just bought my child dream Truck a Ford F-350, 2004, crew cab, Lariat, leveling kit, 6.0 Diesel, 4x4. Iím from European, Germany but I live currently in Canada.
At the moment I have (Ford) Harley Davidson 20" rims with 35" tires, Pro Comp Xtreme, 35X12.50R20. But this setup rub on the leaf springs. And I donít want spent money on spacers.
If I understand everything right, then the backspacing should not bigger than 4.5 inches.
What about the KMC Wheels? They have most likely a backspacing from 4.53 inches. Would that work as well?
If you wanted to save some cash, you can keep the 20" rims and go with a narrower 35" tire. That would probably fix your rubbing issue and save you a little fuel as well. If you want to keep the 35x12.5" side, then you need to look at wheels with at least 0 offset, and as much as -12mm offset. More negative and the tires will stick out past the fenders too far and you'll need flares. I ran 35x12.50 tires on my '03 with -6mm and -10mm wheels, both fit great with the latter sticking out about 3/8" past the fender. Stock is in the +6mm range, so they only need to move out 12-18mm to get enough clearance.
Many will advise you on backspace, but backspace is depended on wheel width to really tell you where the tire will be. Offset is a measurement from wheel center, so it is independent of width and a better measurement for comparison between wheels of varying width.
so after the first seven days consciously searching craigslist (ad hunt'r) for fitting wheels without any success.
I also starting looking for cheap new wheels. My question about new wheels is: Which offset should I prefer to get a 110% rubbing free driving? -12mm?
I XD (made by KMC) Monsters that are 18x9 and -12mm backspacing, I have about .75-1" of leaf clearance with 35x12.5r18 tires (Nitto Trail grapplers). Cartmanea knows his stuff he helped me a lot once I was ready to buy rims and tires.
IMO stay away from spacers unless you get good steel ones and those cost the same as rims so I would count those out if it was me. I would only use them on a show truck since...well its for shows lol.
