Looking to start building a ZJ need info

Like the title says I want to build a ZJ for DD and medium trail use so I can buggy my wrangler. That being said Ive looked at all the ZJ but not sure what model would be the best platform to build on. Ill be swapping my lockers and gears into a XJ HP dana 30 and getting a bracket kit for my Dana 44 rear so axles wont be an issue. Also I was looking at Ironrockoffroad 7" long arm kit. They any good?...I want to clear 35's and would be nice to clear 37's.

Clayton long arms
Trim the hell out of your fenders
You can get 35's under there at 4.5".
37's are too much for an hp30/44 set up under a zj.

Buy a 96-98 v8 for your base platform.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.

Medium trail use and a DD on 37's? To me a medium trail would be a 3.5" lift and 32's. A ZJ on 37's would be trailered. I haven't see the IRO long arms in person but I can tell you that the Claytons are pure beef.

I'm thoroughly amazed you don't chew through ball joints and unit bearings.

Claytons is also 3k not really want to spend that much. Up here in the NW 35's-37's are needed for medium trails. Also my wrangler is on 37's and its a DD.

Ball joints arnt an issue but i go though hubs about every 8-10 months. But they have a 3 year warranty and i just swap them out every 6-8 months. Probaly last little longer if I wasnt banging them around on the rocks.

So why are Advice if you already know the answers? Anybody is going to tell you 37s are too big for a Dana 30 and a seven inch lift isn't a "mild" build.

Agreed.
And you must remember, the grand is a lot heavier than the wrangler. i've seen grands break stuff on 33's that wranglers don't have issues with on 35 & 36's.
And with alloy shafts in there you really need to start worrying about the ring gear in the hp30 over 35's.

Really didnt think about the weight of the ZJ ill plan 35's. 33's are little small for around here.

35s are easily doable. Zjs cost more to lift properly to ensure durability and DD usage.

ZJ's are around 4000 lbs stock. 4.0's are a little lighter. Heaviest would be the 93-95 v8 and the 5.9 right? Probably over 4000 pounds.

I got a budget of 8k I think I can buy a stock ZJ and build it for that. I already got gears and lockers and I just picked up a HP 30 from a 97 XJ today.

I picked up a HP 30 from a 97 XJ that I plan on swapping my all parts into. And im going to use my XJ Dana 44. They have Eton E locker 30 spline front with molly shafts, Eton E locker rear with 30 spline molly shafts 4.56 gears. Not to mention HID off road lights and the dually LEDs, 17in wheels. I can build my own bumpers and rock rails. Bumpers are cheap i could build both for under 250$. All that plus 8K to buy a ZJ, lift, tires and anything else that comes up. Around here ZJ are cheap i can pick a 96-98 5.2L with 145K-180K miles for under 3K.
