3 Iinch lift questions..

[cts]

I’ve been reading a lot of different information about 3 inch suspension lifts and the types of corrections they may require. Since this will be my first time doing this, I’ll list what I already have below and would appreciate any guidance on what I might be missing or will need. I want to note that I’ve been selecting the parts one by one rather than using a complete kit. Thanks!

4 inch Shocks, 3 Inch Springs, Panhard Rods, Trailing Arms, Steering Stabilizer, 2 inch Bumpstops (Rear) And Sway Bar Links (Front And Rear).

That's a good starting point. The specific springs and vehicle weight make a big difference at this height, as you're near the boundary for some of the stock parts. Dobinson's 3" springs tend to result in a lot more lift unless it's a very heavy rig. A panhard relo bracket is a nice option for the rear instead of a new adjustable bar. You might not need rear UCAs...but you might (could be a wait and see item.) A new steering stabilizer isn't needed just because you lift the ride height. You likely don't need quite that much rear bumpstop, but it will depend on the compressed length of the specific shocks you pick - or the size of the tire you want to run. Most 4" shocks will need extended brake lines and diff breather hoses. You will also need to correct the castor with plates or new front radius arms.

Thanks for the detailed feedback. I already picked up the adjustable panhard bars, so I’m going to run it for now and see how it holds up, then upgrade to a rear panhard relocation bracket later if needed. Same idea with the UCAs and steering stabilizer, I might as well throw those on while I’m in there. I’ve also added extended brake lines, a diff breather, and caster correction to the list. As of this moment my lc is all stock, I plan to order 35s once everything else gets here. I was also reading that I’ll need at least 2 inch rear bumpstops for larger tires but what about the front, is anything required?

2" rear bumpstops and 1" front would be a good starting point. The compressed length of the shocks is the first consideration and then preventing tire rub comes into play. Anything more than ~15" compressed shock length R or F will need to be accommodated for with bumpstop extension. The 2"R/1"F extensions will protect most shocks in that range from over compression and also work well to clear a 35" tire.

Dobinson Front IMS45-60912 - 4" Long Travel Monotube Shocks
Dobinson Rear IMS59-60687 - 4" Long Travel IMS Rear Monotube Shocks
These are the shocks I have.^^

I've never used adjustable UCAs. Most I've done is use a stronger arm at the factory length.
