    Ok Not that type of lowering lol.
    So I'm wanting to change out the suspension on my new to me LJ.
    Specs are..
    -05 LJ Rubicon
    -fabtechish suspension, 4 link front and rear. Fabtech cradle with link mounts, tube links, fabtech springs. Custom weld in adjustable spring upper mount with bump stops.
    -Fox 2.0 shocks
    -Tires are 37x13.5x20s
    -1.25" wheel spacers.
    -Psc assist steering
    -Teraflex high steer steering arms and knuckle
    -Adjustable trac bars
    -Currie antirock sway in front..*not yet installed

    I measured the springs and compared them to stock measurements. Looks like around 8" lift. I'd like to get around a 4" lift and use a high fender setup. Would like the springs to be softer and flexible. The tires are being replaced with 35s. This will be a weekend ride, so must be street driven some and able to hit mild trails.

    So the question is, what all has to be changed with the suspension changes?

    Driveshaft shortend? 4 links shortened? Adjust trac bar? Different shocks?

    What say my nc4x4 brethren, is this worth changing? Thanks

    I’d keep the 37s, ditch the fenders, smaller coils and bump stop before your tires rub. Driveshafts should be good.

    I think most people run that setup anyways. I didn’t know they even sell 8” coils anymore :D

    With high lines you can easily run 37’s with 3-4 inches of lift.

    On my old tj, I ran roughly 2 inch springs, tube fenders and 35s with no problems.

    Not sure what you would need to change out with your current setup though.....

    Thanks for the replies. I'm still looking at what needs to be changed out for the smaller lift. How does a front dana 44s hold up to 37s. Oh and I got some more of those too..

    Trussed, gussets, chromos, and a proper gear set up will hold 37s on a 44.

    I doubt you'll have to do much other than adjust links to get pinion angle back to acceptable after dropping to 4" springs. Be careful with that steering, fairly certain they require at least 4" of lift to clear. if your bump stops don't get shorter (assuming it was done properly to begin with) you can keep the same shocks.

    Shocks are important for the smooth ride. Fox IMO ride stiff. Synergy or RE springs are good quality. I’m running RE springs and Fox Factory shocks on my stretched TJ and I think it rides okay but could be a softer ride on the highway.

    I ran the rs5000x shocks on my old tj, and imo they were perfect. Not as harsh as bilestien, fox, ome , ect.....

    Take some more pics of the clearance between the arms and frame, but you should be able to go down to about 3" lift without changing anything except shocks and springs. And if you're doing that, you should really just pony up and do coilovers :D

    But some OME springs and shocks (or maybe you can keep your shocks depending on length) is a good starting point.


    PS, I have some AEV highline fenders that I'm pretty sure are that exact color of your Jeep and some proper ARB rocker guards that have been trimmed to fit with the AEV fenders...

    There's definitely room to come down 3-4". I think if you go much more than that, you will have contact issues where the rear lowers mount to the frame. The Teraflex longarm kit on my TJ is similarly mounted and has some issues at less than 3" of lift.

    So I'm looking at the currie savvy 4" springs. I was thinking about alignment. For a lift that size what are some numbers for caster, toe.

    Thanks. I need to record all the measurements before I lower it. I've ordered a set of 4" currie springs and a set of rancho rs5000x. Price was to good. I wanted to give them a try. Hopefully next week I can start. I've got a big shipment from Brad @Barnes 4wd that I'm waiting on. Then I'll take the jeep on its maiden voyage
