Sorry, had to revive for a question.

How are guys generally measuring "lift" here? I see a lot of rigs that don't look as tall as my 6" on 35's, but claim 8" on 38's, or rigs that look 4" taller than mine, claiming 3" lift.

Yea, I get that bigger shoes = more chassis lift, but I generally go on axle to frame distance vs. stock. Reading through other guys numbers posted here, seems like half are measuring frame to axle and the other half are measuring frame to ground (and then a few guys ... I've got no effin' idea).


I've got 6ish inches of lift over stock measured from axle to frame, on 35's. That to me, doesn't seem anywhere near low COG. Generally what frame/axle or frame/ground numbers are we looking for before calling ourselves low COG?

always measure lift in the change of distance as it relates to the axle/frame from the stock location. getting height from a larger tire is not a lift.

My thoughts as well, but looking at a lot of these pictures, I suspect not everyone does it that way.

Here's mine for reference, sitting on 35's.

Damn, that's really the only shot I have of the Jeep sitting level. Took a while to find.

Ass has moved up about 1" after adding another leaf to the 63" pack to level things out and stiffen it up.
Relative to stock height (measured axle to frame):
Front = +6.5"
Rear = +5.5"-6.5" depending on load





I think I get about 10" uptravel in front and around 8" rear. No idea on droop. All I know is it'll drop far enough for my coil to fall out, but that never happens because my brake lines hold it all together Rear drops a LOOONG way. Probably too much droop on both ends. I don't understand how anyone has issues with flex with radius arms.

All that said though, this junk is nowhere near low COG imo. I'm trying to figure a way to drop the COG at least 2-3". Not sure if I'm going to drop COG by adding un-sprung mass, or removing the roof rack (it's only about 80lbs), or removing the spare tire, or saying fuck it and just build a cage and stop worrying about it

Who's got suggestions on lowering the COG? I really do like my clearance, but I don't mind moving to 37's and dropping suspension an inch or so. The 5.3L I think really increases the COG.

judging by your shock in the first picture, id say more like 5ish" up travel up front.

if you really want to drop the COG, the most obvious answer is use lower springs, and measure for new bumpstops and shocks.

Yea, and I may lower it, but there are a few issues I'm not really sure resolving is worth it.
1. I'd have to do way stiffer compression valving. Junk is 5000lbs now and I bottom it out constantly, both front and back (treated like a bitch). Running ... whatever shocks bilstein valves for a newer rubicon with 5" lift. Don't recall the numbers but they're already pretty stiff. I'd probably have to upgrade to a rebuildable/revalveable shock to deal with the high speed compression. That said, I've been thinking about going that route anyway. The bils are nice for a weekend bomber, but no where near what I'd ultimately like.
2. I like my ground clearance. It's just right for the terrain in the area. I'd be on 37's now if I thought my poor axles could deal with it, but ya know.. It's also my DD (which is sorta the point of this build). If I go tonnes, I solve the COG issue as well the shoe size limit all in one fell swoop. Starting to think more and more that the tonnes may be the answer.

My rig in it's finishing stages. Dodge 60s full widths and 37s, Front measures about 4 inches over stock, rear measures 3 with spare and gear in it, 18 inches of clearance too the lowest brackets, 24 inches of clearance too the box sliders(will be boat sides after plating). Amazingly stable compared to the same height on 33s and factory axles.

*edit* just realised I already posted on this, but plans have somewhat changed.

I don't at all consider my heep LOW COG, but it's not horrible. That said, I'm currently trying to find ways to lower it without going tonnes (I really don't like giant pumpkins, I don't want to run 37's to keep ground clearance, and tonnes + dd is a bitch in Canada).

98 XJ, 5.3L/4l65e, plated/braced, 35x12.5", 6" front, 5.5" rear, 63" chevy leafs rear, so I can get loads of up-travel (once the comp-cut is done), currently weighing in at 5000lbs loaded.





Yes, roof basket isn't helping, nor is the spare tire carrier. I'm addressing that right now. Unfortunately, I absolutely need a full size spare as well as enough tools, recovery gear, and camping gear (just in case) any time I'm out of radio range (long story short, health issues. can't afford to be stranded).
With tools and emergency gear in the back, there's no room for a 35" spare. I figure I can either mount the spare on the roof (I'm not sure if this'll increase COG or not, cause it'd only be the tire, and the swing out would get cut off), or cut out the hatch to make the spare fit on the floor. At the same time, I'm planning on caging right soon. That removes the basket and swing out, but still probably adds most of that mass right back where I started.

I can probably drop the front down an inch or two, and once I've got the rear wells comp-cut, I can drop it 1 inch. This will help, but I feel like I really need to either add unsprung mass, or decrease sprung mass.

Thoughts/suggestions? How much will losing the basket and spare really help? I'm real close to tempted to just chop a few inches off my front coils and bump stop more aggressively, but on the high speed stuff, I'm already bottoming out often. Both the front and rear need some stiffer shocks which may help a bit on the compression, but either way, lowering it more than an inch just ain't in the cards with how I wheel.

I have 14s front and just put them on the rear. I was running them 6-8" but think I'm gonna run 4-5 just wondering how the ride would be.

If it raises the rig it's considered lift ...your COG is raised be it from adding a 2 inch coil spacer or going up 4 sizes in tire . measuring from axle to frame only tells you how much suspension lift you have over stock measuring from ground to roof---if you still have stock one---tells you how much overall luft you have over stock . from level ground to frame works as well .

when you talk about how much lift you have, measuring the lift from tires doesn't count.

thats all im saying.

I built a very similar XJ earlier this year. 44/9 on 37's with roughly 4-5" lift and 5"/3" stretch.

You have caused me to potentially waste my first new born, in my pants.
