It's one of those modifications that seems a lot scarier than it actually is, but it's a rite of passage for almost anyone looking to take their Toyota FJ Cruiser further than the stock look.
The FJ is a beast off-road, but it has some tight tolerances within the wheel water wells. Once you move previous a standard 265 or a little 285 tire, that big chunk of steel holding the particular body to the frame starts getting in the way. It's positioned right behind front side wheels, and when you're at full locking mechanism or compressing the particular suspension on a trail, the car tire as well as the mount desire to be in the same place at the same time. Spoiler alert: the tire always loses that fight.
Why You Really Need the Chop
You could be considering, "Can't I simply obtain a bigger lift? " Honestly, that's a common misconception. Lifting an FJ Cruiser moves the resting point of the suspension, yet it doesn't replace the arc that the particular tire travels when you turn the wheel or when the suspension cycles up and down. Whether you have a 2-inch lift or perhaps a 6-inch lift, that body mount stays in the exact exact same spot relative to the tire's sweep.
The issue usually starts whenever you jump to a "true" 33-inch tire or anything larger. Despite having a high-clearance bumper, you'll find that as soon as you back out of your drive and cut the wheel, you'll hear that rhythmic rub-rub-rub . It's annoying within the pavement, but it's actually dangerous within the trail. If you're aired down and crawling over a rock, that body mount can work like a dairy products grater on the costly new rubber.
Performing an fj body mount chop solves this by bodily removing the corner of the bracket that protrudes into the wheel well. It creates the measurement needed for the tire to swing freely through the entire range of motion.
The particular Fear of Slicing the Frame
It's perfectly regular to feel some hesitation when somebody tells you that will you need to take an position grinder to your truck's frame. It sounds permanent since, well, it is definitely. But here's the particular thing: the body mount is overbuilt for what it does. By "chopping" the corner and welded in an encouragement plate, you aren't compromising the structural integrity of the vehicle.
Most shops that focus in Toyotas do this almost every solitary day. If you look at a professionally done fj body mount chop , this looks like this could came through the factory this way. It's a clear, boxed-in piece associated with steel that clears the tire whilst still providing almost all the support the particular body needs.
Can You DO-IT-YOURSELF the Body Mount Chop?
When you're handy along with tools, you may be tempted to tackle this in your garage. Whether or not you should depends entirely on your own comfort level along with two specific equipment: an angle mill and a welder.
The cutting part is definitely straightforward. You'll need to pull back the plastic inner fender liner, mark your line, plus start cutting. Nevertheless, you can't just leave the mount open. In case you depart it being an open up "C" shape, you're inviting rust plus potentially weakening the mount as time passes. You need to weld a steel dish on the opening in order to seal cracks back up.
When you've never selected up a welder before, this possibly shouldn't be your best project. Since it's attached to the frame, you want solid penetration in addition to a clean bead. If you aren't confident in your own welding skills, it's worth the couple hundred bucks in order to have a regional off-road shop perform it for you personally. They'll usually have the pre-cut plates ready to go and can hit it out within an hour or even two.
The particular Step-by-Step Reality
For those who else are going to proceed the DIY route, here is how the fj body mount chop generally goes straight down.
Initial, you've have got to create some room. You'll want to eliminate the front tires and pull back again the fender line. There's plenty of plastic material in the method, as well as the last thing you want is a fire because the spark hit the dry plastic clip. Most guys use a bungee cord to pull the liner back from the splash zone.
Next comes the marking. You aren't cutting the entire mount off—just the particular protruding corner. You want to mark a diagonal series that gives the particular tire clearance but leaves enough area for the rubber body bushing to sit securely.
Then comes the loud component. Using an position grinder with a cut-off wheel, you carefully slice through the heavy-gauge metal. It's messy, it's loud, and you will have sparks everywhere. Once the chunk of metal is out, you'll work with a grinding flap disc to clean out the sides and prep the surface for welding.
After the area is prepped, you tack-weld the "fill plate" (usually 1/8" or 3/16" steel) over the hole you simply made. Once it's completely welded, you strike it with some black spray paint or even bedliner to prevent deterioration. The result is a much narrower mount that stays out associated with the way of the meaty new tires.
Common Misguided beliefs and Mistakes

Several people play the role of "conservative" with the cut, only to discover out that as soon as they get upon a trail and the suspension compresses, they're still massaging just a tiny bit. It's better to do it once and do it right.
Another myth is usually that an positioning can fix the rub. While it's true that the good alignment technician may "push the tires forward" by altering the lower control arm cams (increasing caster), this only does so very much. On an FJ Cruiser, despite having high caster settings, a 35-inch tire is still going to need piece of that will body mount. Don't throw away cash on several alignments trying in order to avoid the unavoidable.
Life Following the Chop
When the fj body mount chop is completed, the difference is definitely day and night. You'll finally be able to do a U-turn within a car parking lot without people staring at your own truck because of the "crunching" audio. More importantly, you'll have peace of mind when you're off-roading.
You won't have to worry regarding a sharp advantage of the body slicing into your own sidewall when you're stuffed right into a wheel well. It's one particular of those mods that you simply don't actually "see" once the particular wheels are back again on, however you certainly feel the benefit each time you drive.
If you're planning on keeping your own FJ for the long time plus actually using it intended for what it was built for, simply bite the bullet and get the chop.
