LJ 4” Spring Suggestion

[Wild Willy]

I am looking to install 4” springs on my 2004 LJ which has a 2.5” EMU lift already. Is there a preference on brand, constant coil and should I use a taller spring in the rear being an LJ so that is level?

Rockjock/currie. They have coils in increments for the back. Depending on the weight of your jeep.

Second the rockjock suggestion. They have an LJ specific rear spring that is slightly longer to compensate for the additional weight. Without my spare tire, I get a slight rake with these springs, level to very small rake with the spare tire.

Checking with them, thanks.

Yeah, I have the RockJock RH3P on my LJ and they’re too long for my light rear end, so I’m planning to swap in the RH1.

There is a RH2P that splits difference and is the regular 4in tj rear spring, 3.5 on the LJ

I had just ordered the RH3P I which mentioned to them that I have a fullsize 33” spare on the back. I hope it works out ok! Thanks everyone for being so informative.

Right, but I need way shorter. I’m at about 5.25” loaded. I want to be at 4”.

After you mentioned it, I measured my rear shocks with the spare off and all the new aluminum armor on. I have about 2 inch of droop left. I may need to make some changes if I keep the spare off.
