Well, quite a few people have asked how I made them fit. So, here goes:
First, I know of the possibility of breakage. I run a 89 4Runner with a Ford 5L V-8 and 38.5" Swamper SX's. I know all about breakage. The axle in the front of my 4Runner was designed for 4cyl use. It's survived (for the most part).
The IFS in the Cruiser is the same as the one in the 05 4Runner with stock V-8 power. I'm gonna guess it's at least as strong as the 4cyl stuff.
I know we are comparing IFS with solid axle stuff, but it's gotta be close.
Anyways, when I first started test fitting the 37" Krawlers on my first Cruiser, I knew right away the front bumper had to go. They would rub the inside of the bumper with the wheels pointing straight.
It was also obvious that the body mount needed to be trimmed. But we've all seen that done. This was my first attempt. It needed more trimming. You can also see the pinch seam that will need to be flattened over.
I then had an unfortunate accident. The road was washed out in a winter storm.
I got another Cruiser, trimmed the body mounts more than my first try.
They don't rub on them, anymore. They don't rub on the front bumper, anymore, either.
I had to trim the inner fender liner for the bumper, and to clear the front of the tire. This is normal with an aftermarket bumper.
The tire cleared the UCA when there was only 6 psi in the tire. But when I aired them up to 30 psi, they juuuuust touched the UCA. They also juuuust touched the caliper. For now, I have a 1/4" spacer in there, and it clears fine. I have since replaced the lug nuts that are in the pic.
I trimmed the bottom corner of the flair, where the front mud flap mounts. I also trimmed the inner fender liner at the rear of the front wheel well. This exposed the pinch seam. I folded over the pinch seam, as well as a small bracket that the mud flap mounted to.
It still rubs on the inner part of the front fender flair. It needs some minor trimming. The rear already has this trimming from the factory. First pic is the front, second pic is of the rear with the half moon shape made to clear the tire.
The rear is very close to rubbing, but so far clears everything except the mudflap.
Finished product. Well...it's never finished.
