Build dilemma - how to spend the remainder of my budget?

My frame is shot and I'm going to move everything over to a good one. We're going to use this as an opportunity to do some other mods, including outboard mounts on the rear, higher shock mounts on the front, raised body mounts, and a tummy tuck. I started with a $10,000 budget but spent $4,000 on a new welder, plasma cutter, air compressor, and all my safety and welding accessories. I'm keeping a thousand for unforeseen problems, $1500 for tires and wheels, and that leaves me $3500 for parts.

We are going to be swapping my rear axle out for something else, either going cheap with an 8.8 with artec truss so I can do a few other things with my budget, or going for the g2 rock jock 60 which is going to take up most of the budget and force me to hold off on some other mods for a while.

If I go with the 8.8 which is already geared 4.10, I will be swapping in an HP 30 with 4.10s. If I go with the rock jock, I will be ordering it with 4.88s and use my current HP 30 in 2wd until I can afford to regear it. I will be going with 35" tires.

The mods I would have to hold out on by going with the rock jock would be sleeves for the Dana 30, new shocks, front and rear track bars, and taller springs. I'm currently running the h&r 1" lift with a full set of adjustable short arms, but was going to step up bigger if I went with the 8.8.

Don't you think a 60 is a bit of overkill?

Have you done brakes?

Steering?

I don't consider the rock jock overkill for 35s. It has excellent clearance and the 8.8 has a weak carrier and axle flanges which would eventually need taken care of. A built 8.8 is just as expensive as the rock jock, the difference would be that the 8.8 can be done in stages and the rock jock is all upfront.

I upgraded my steering a couple years ago but I'm still running stock brakes. The vanco stuff will be on back order for quite a while.

Saying the 8.8 has a weak carrier and flanges is like saying the RJ60 has a weak ring and pinion because it's high pinion.

I would go with the RJ60 because of the ground clearance.

Could you save money by ordering a RJ60 axle assembly without brackets on it? And then burn your own brackets on.

Or maybe a 9" all setup without TJ brackets?

Have you considered changing the rear suspension? Now would be a great time to do a 4 link with the tub off the frame and a new rear axle going in.

Yeah I was going to use the opportunity to do a new suspension but it won't fit in the budget right now. I'm going with the new shock mounts now for the ease without the tub on, it will make things easier down the road if I go with a long arm and coilovers next year.

8.8 was a great option 10 years ago, but there were no G2 RJ60s back then.

Would you be getting Set 20 bearings with the G2 RJ60? Don't buy one with Set10 bearings.

You have to watch those G2 axle assemblies with the parts they use. Sometimes they are cheap for a reason.

I've had an 8.8 for about 10 years now. It has held up pretty well, but if I could do it over, I'd have a 9" or RJ60.

If you're doing the work on the shock mounts - how about longer / better shocks to really take advantage of it?

Otherwise... if there's other stuff you want that's not in the budget right now... just keep saving.

Yes I will be doing shocks with the mounts, no choice there. It will be some cheapies for the times being. I think I have pretty much settled on the RJ 60. I don't absolutely have to go to 35s when we do this, I just bought a brand new set of 33x10.50 bfg at's for DD tires a couple weeks ago, so I can drive on those for a while of I have to. I am going to help my gf get a TJ when I get some of this build done and was going to give her my take off arms, springs and shocks.

I will call g2 tomorrow and see what options are available to me. I'm wondering if they set up the brackets specific to the amount of lift you need, including a tummy tuck.

I'm betting all the brackets are setup the same according to one jig, but it would be good to have this confirmed from you calling them.

Also ask them how cheap to get a bare tube assembly. Maybe it'll save you $450-500? Then buy brackets/truss with that savings, essentially get paid to install the brackets yourself. Wait, did you say you just bought the welder?

Lol yeah we can set up the brackets if we need to, but it would be outside of the jeep, before we switch everything over, so it would be nice to know the pinion angle range we would be aiming for. Eastcoast gear supply has a pinion angle chart for their 8.8s that is based on lift height, so I was hoping g2 had something similar. Guess I'll find out tomorrow.
