Default Lowering 02 4x4

Right now I currently have 2" shackles, leaf spring blocks removed, and my torsion bars cranked. I'm planning on getting spindles as soon as I can get a hold of some 17's. Would I be able to install hangers too? I was told if you go more than 4" in the rear you'll need a flip kit. Is that true?

Unless you can handle the axle bottoming out into the frame occasionally, I'd recommend a notch at around 5" rear drop.

Did you go with a notch on your drop? How'd you get 5" in the rear?

with blocks, shackles, and hangers you should NOT need to do a c-notch. However, if you do not relocate the bumpstops directly to the frame(4WD has a bracket they mount to, remove these for more clearance), you will hit all the time. You may also need to cut them down some for a little extra room. Some helper bags in the rear will make sure you dont bottom out.

Notch it and flip kit it. Flip kit is so much easier. The notch makes for a much better ride. I wish I had flipped and notched mine instead of shackles and hangers. Then dealt with it bottoming on the frame for years.

Will there be any drilling or welding involved to relocate the bump stops?

I've considered it, I just don't like the idea of cutting into my frame.. not confident enough to try cutting into it either haha. Shops up here in alaska charge outrageous for stuff like that too.

No drilling, cutting, or welding. It's all just a few nuts and bolts, and I'd be happy to help you get this done.

It's not as expensive as you probably think it is. A good notch kit is plenty strong. The Bell-Tech is a really nice one.

Notching the frame is no big deal so long as you have the right tools (good sawzall, blades, angle grinder w/cutoff, cobalt drill bit, etc). Without the right tools you might be pulling your hair out like I was until I bought good stuff....
