With a wheel opening that’s not three sides of a perfect square, you’re going to have to spend some time deciding what looks right to you. When you’re installing a new rear suspension, you have the ability to fine tune the wheel location, and fine tune you should. Look how the gap ahead of the tire opens up substantially in the first picture. This is why it’s important to have at the very least the diameter of the tires you’ll be using. If I was using a shorter tire, it might look better a little closer to the ground, for instance. Have a look at the pictures and let me know if you agree with our determined wheel centerline.

Here?

Or here?

Maybe here?

Yes, here.

We measured from the door opening on the cab just in case the box had shifted a bit since I already took the bed bolts out.

To transfer the centerline to the frame, we could have used a laser level, OR just let a string hang between the axle centerline marks on your fenders, then pull it up slowly till it reaches the frame and make a mark.

I think this frame will be great for a four link. We can mount the lower bars outside the frame rails which will leave a lot of room for exhaust, etc.

I don’t think a step notch will be necessary at this ride height, which will be great because we won’t have to modify the bed floor. edit: Yes, it was necessary 🙂
