Alright guys, my friend and I are having a debate over articulation and how it is affected by the size of your lift/coil spring. On the front of a Cherokee, does the coil spring height affect articulation given the same LCA's, and the correct shock/swaybar combo?
example: lets say we are running the EXACT same Long-arm set-up on 2 cherokees. The cars have the same shocks, tire/wheels, and sway disconnects. One car has 6.5" coils and one has 8" coils. will the 8" lift jeep articulate more? if so, will it even be worthwhile?

He thinks money spent is going high, I think money spent is modest lift and lockers. Given the same money being used in either case.

I know this is a kind of rediculous arguement, but I cant find enough information on this to get a concrete awnser.

thanks!

 

Lift height does not equal articulation

 

Ah I see what might make the difference...is CARS tend to not get lifted but Jeep CHEROKEES do
Lol

Any ways remember in a VERY simple put way lift is to get bigger tires. Bigger tires is to get your axle off the ground. So a in sure others will say, its how well you can get a good balance between height and tires. there's a guy here with a amazing Jeep cherokee that is all about lcog. Can he articulate and stuff his tiremore than a eight inch suspension, maybe. But look at buggies, they're not very high and can squat and articulate like crazy. My two cents. I'm sure others can input with better info

 

Yes they will articulate the same amount but usable articulation won't be the same. If the coil isnt even touching the vehicle it doesn't really help much with traction. I think 6.5 inches is still too tall. 5 is about right.

 

Side not, bigger tires are also used to make obstacles smaller.

A 31" tire crawling over a 25" ledge will be more of a challenge than a 44" tire crawling over the same 25" ledge.

 

You also have to consider what you are doing with the center of gravity, you may not be able to flex it out for fear of flopping with an 8" lift.

 

I am told all the time I have to much flex and I am at 5.5" of lift on 35's... its all droop.

you could lift a vehicle 18 inches and only get 3-5" of flex, or lower a vehicle, and get 20 inches of flex. all depends on the limiting factor of the suspension. Lift height has really NOTHING to do with flex at all. it comes down to the shocks, brake lines, steering, control arms, geometry, ect. What binds first is whats going to limit your down/up travel.

 

are long arms the best bang-for-buck upgrade to get better articulation and effective flex?

 

You can get pretty good flex out of adjustable short arms with drop brackets, but a well set up mid or long arm suspension will outflex it anyday. The limiting factor between the two is normally shock length. You can only squeeze so long a shock on a cherokee. I have 12s in front and 14s out back, and the 12s are still my limiting factor up front.

 

if you had a re-do what front/rear length would you have gotten.

 

You don't need lift to flex , But you will need it on an XJ if you want up-travel , and ultra low lifts with big tires are all or mostly droop ,which will suck if wanting do go fast whopps type wheeling ...An XJ with a 4 inch lift an 38's will flex big time if the shocks are long enough and the coils trapped ,but that rig will not be friendly if trying to go fast on big bumps and jumps since it will have no room for compression .

 

I see that argument as big gay truck vs a usable trail beater, but its all really about the use of the vehicle. Pure mudding, yea you want it sky high. For crawling and trail riding, you want it alittle lower to reduce your center of gravity. Flex is all about how many $100 bills you rub your suspension with, it can go both ways. And yes shocks are always the limiting factor in flex, hence why you see people cut holes in their floors and hoods to put longer shocks in.

 

Low cog... 4.5in lift... 40's but I got a deal on them... I could fit 46's easily... Super duty axles which are wide as crap (forget wtw now)... Mines not going to be so much about up travel but thats fine because I got low cog and dont really need to stuff all to much...

 

Yea but climbing a 25" ledge with a 31" tire is so much more fun than it would be with a 44" tire

 

And thats KTM's low cog thread by the way... And I know many have seen these but heres mine and its stance...
