I'm running 37X13.5's on 20X12's now with a 6" lift W/ minimal rubbing issues. The only place it slightly rubs (very seldom) is on the plastic of the inner fender-well. I'm planning on modifying that so that i don't have any issues.
My current setup is Icon 6" front springs (it's a 2001). My wheels have 4.75" backspacing.
What manufacture is your wheels? Wonder if I went up to a 20x14 and the maximum backspace I could go if they'd fit. I'm going to have to mess around with that
That's what I'm thinking. Wonder how much modification I'd have to make for it not to rub. Can you post a pic of your truck? I'd like to see how far the tires stick out
I'm running about 6.5"s of lift and 20x12s with the 37 mud grapplers and it rubbed more than I thought it would. I had to cut about 1/4-1/2 an inch off the rear of the front fender and a little metal trimming in the front
I'm interested in the same kit as you too. I'm getting ready to replace my sway-a-way Coilovers and switching to the 4.0s. Hoping I can get Fabtech to just sell me their shock towers and shocks.
When I talked to our rep at FabTech, he explained that the towers and shocks have different mounting brackets, which were of course only sold as a whole 6" lift kit
what do you mean different mounting brackets between the shock towers and shocks? I was at a offroad shop yesterday that deals a lot with fabtech and he told me that he would be able to get the towers/brackets as well as the coilovers for me without getting the rest of the kit since that's all I need to fit them.
I would think you would be ok with the 13.5 wide tires on 12" wheels. The 14" wide wheels are going to be tougher to fit and you probably would need a bigger lift than 6".
Have you had a chance to ride in a truck with this setup. Typically they ride a little stiff. Then when you combine it with changing your wheel/tire setup it may ride worst then it does now with your current lift.
My truck is already higher than 6" and I'm running the 37's. It does ride rough but I'm trying to clean that up with the 4.0 coil overs.
I've ridden in a buddy of mines 6.0 that has the whole kit and his rides smooth. I'm looking for similar ride quality.
And the guy that I spoke to on the phone at Fabtech said something about the coil overs needing a different attachment method or bracket for my year truck (2000 F350)
Yes if your truck has leaf springs right now. You will need to do some work to install that kit. It may even be cheaper just to upgrade your front leaf springs to Icon or Deaver and get some new shocks. That makes a big difference as well in ride quality. The coilovers really gain you a tighter turning radius. In my experience it is marginally better ride quality going from leaf springs to coils when you are comparing good quality kits.
On your 17's on 37's have you reduced your air pressure in your tires? That makes a pretty good difference as well to run at 40 or so psi.
It is easier and you will be better off just buying an 05+ front axle and getting some coil buckets and a few other parts and then just installing a newer kit into your truck. It will drive better and you can even get those axles for like 500 bucks now. Better turning radius, bigger brakes...just better axles. Everything just bolts all right in. Versus trying to fab something up and ending up with something that may or may not work in the end.
Essentially you need everything from the frame of the other truck.
Coil Buckets
Steering box if you can
track rod bracket....but you may get that from whatever 8" kit you end up with.
Radius Arms (Only if your new 8" kit doesn't come with them)
Radius Arm frame mounts
Swap the ABS sensors from your old axle into the newer axle
If you keep your old rear axle then you will need wheel spacers to make them the same width. We did that on a friends truck. No big deal...and you will have a different set of lug nuts for the front versus the rear. Threads are different.
You will need to do a little work depending on your setup to get your newer steering box to hook up to your old pump. It isn't really a big deal. Sometimes they go right in other times you need to find a fittings/hydro shop that will easily make them work.
Then lots of grade 8 bolts. Most of the holes line up and there are a few to drill. This is one of those projects that you need a couple good weekends to get it done.
