I have a 2/4 drop and I'm putting a c notch on soon. I want to do it ASAP but I'm confused on whether or not I need to adjust my pinion angle before I can mark where to place the c notch? I've read that the axle does not match up with the stock bumpstop when you lower it so you mark it before you cut your c notch but will a pinion shim move the axle to a different spot on Frame? Last thing I wanna do is c notch the truck and then I buy pinion shims and when I install them the axle starts hitting the side of the notch. Anyone know?

 

The shims don't move the rear enough to worry about a c notch. I did a 6" flip kit and installed shortened bump stops in the factory location.

A drop kit should not be changing the wheel base of the truck.

 

The correct way to do this:

1. Remove the rear tires.

2. Disconnect rear shocks and sway bar (if equipped)

3. Jack rear-end up until it touches the frame.

4. Mark.

Don't overthink this. It's quite simple. If you don't want to fk with shims, I'd recommend the DJM flip kit as it gives you the ability to adjust the pinion angle to whatever you want.

 

Not the wheel base but I've seen pictures where the factory bump stops don't line up with the axle when it's jacked up.

 

I'm already lowered and don't plan on going any lower right now haha but if u do want to go to a 4/6 from my 2/4. I have coil springs, hangers and shackles. To achieve the 4/6 what would be the easiest way to get to it. Could I just buy 2" drop leafs and then 2" spindles?

 

Hangers are an ***. I would do a flip kit/stock shackle setup. That will give you 6 in the back.

For the front, I would do spindles. Using quality shocks will also be needed.
