Tell me more about these 19" tires. That may do it on the from. I got a rough measurement of 9.5" radius.
18 and under it can be both. From there up it's probably just the OD.Marc T said:So the problem is with the width of the caliper not the OD. Or is it both?
You rock BoomerBOOMER said:what i have noticed since i have been installing the lowering kits we make is it is also a matter of the aluminum knuckle that your A arms attach to. with an 18" wheel, it angles towards the wheel and the smaller diameter wheel would touch it, i think that is why fastjack could only run a 7" wide 18" wheel. the inside diameter contacts the knuckle. PS, with our lowering kit to put the front springs in, only takes 5 minutes! i will post pics of the knuckle i am talking about, and a step by step pictionary of how to lower the truck next week. very easy. only need a jack, 2 stands and some sockets.
