what is ck5's take on the graderball?

[55Willy]

just looking for options as i hate rear overhang.

yeah or neah? very little if not no street use.
this is for the rear.

good question... see lots of pirate posts about it but not much over yonder. What rig is this for? You can get close to zero overhang with 56s and big tires if you're talking fullsize chebbie stuff here. Personally, if I was going to go links or whatever to help with overhang, I'd do it in front first.

wth is graderball...?

 

[sled_dog]

a 1 link suspension. Single arm hard mounted to the axle and a single pivot point, usually up under the driveshaft. Cool factor, driveshaft and pinion can be protected if you make a skidplate over the "link". I don't know nearly enough about it to weigh in on this unfortuneatly.

Kinda like the trailerhitch and ball suspensions ive seen on pirate? hmm seem cool but how well do the actually work compared to say a 4 link?

not kind of like, is

the yota.
I'm thinking of this or 64's but 64's have 32" of spring before the shackle.
you'd ned nering 40's to cover that length. I'm running 35's now and going no bigger then 37's

Sounds like a "gimmick" more than a revolutionary new suspension idea.


A converging V-link from the rear axle with a panhard bar to locate the axle could be done with a single large heim joint.... unless the graderball was VERY cheap (or free!) it doesn't seem like it offers anything unique.

misalignment seems to be the gain with a graderball. You could theoretically spin the axle over completely and not bind the graderball(of course the panhard wouldn't be happy).

Heard a few guys say their setups were a little sloppy in the graderball/receiver area.

grader price is $160 for everything new on it.

wouldn't it take over a 1" heim to do the same??

I got those rebuildable TeraFlex 1.25" Rod Ends for around $110 ea. IIRC (It's been a while....maybe the prices are higher now??)

The graderball has unlimited rotation, but with all the other limitations (springs, wheeltubs, frame, the links themselves) I doubt you'd bind a standard rod end before having SOMETHING else binding or interfering....

Elliptic

I think I'm gonna try it, now the choice is xj coils or build some 1/4 elliptic packs?

I saw it on a CJ-8 a few months ago. I immediately liked the idea and would like to build a project with this set up. I also really like 1/4 ellipticals so that would be my vote

 

[55Willy]

well the more I think about it the coils would be easier to build in. take too much hairpulling to get the leafs to not hender flex at the axel mounts. just build 4 coil buckets and move them around til happy.

also looking at a watts vs a panhard bar???
