Correct. OEM bolts and nuts. I don't see why these would be a one use item as someone mentioned. Nor have i heard or seen of anyone bending or breaking them, so no need to replace IMO.

The FSM labels them as no-reuse. Given the torque spec, and the consequences of them loosening and backing out, I can see that. Having said that, I've loosened and retorqued mine. I'll replace them when I do new arms soon. I wouldn't consider it a "run-out-and-do-it-today" item, but if you were going 75 MPH when one finally came out, that would kinda suck... Prolly ~$50 for 8 new ones, including nut and washer.
 
Question for everyone, why do people need adjustable arms? I am just trying to figure this out as I plan on lifting my hundy soon and just want to know if this is another part I will need.

You don't need unless your plan includes lifting over 3 in. and if you are, cool. Can't wait to see it.
 
Unless you are lifting over 3" stock length lowers will work just fine. People use adjustable uppers to adjust pinion angle. In most cases with 3" of lift it is not required, some just like to fine tune the angle.
 
80 and 100-Series Land Cruiser's are notoriously sensitive to drive line induced vibes post lift. I've got a lift induced driveline vibe that shows up in the 65-75mph band (when the AT's are on the rig :D), not too bad albeit, but...long story made short...I'll be fabbing some new adjustable uppers, again, to get the pinion angle back down a degree or two.

No vibes = no need for adjustable rear control arms/links (unless you're trying to change the rear axle position relative to bumper clearance).
 
So these would be a good investment then I guess. My plan is to do Total Chaos UCA, front and rear Radflo remote reservoir shocks, BIO diff drop, Iron Man 4X4 rear heavy springs and torsion bars. My goal is good articulation and I would like to be close to three inches of lift while making everything reliable as possible. If the new arms or links would help keep my angles aligned better so I don't where out ujoints then that seems like a win win.

Exactly right. Even in the case of vibration, adjustable uppers will handle pinion angle change. Adjustable lowers are used to change the axle position. Keep in mind that with stock length links the tire will be in the stock position in the wheel well when stuffed.

A couple people have mentioned problems with bigger tires hitting a bumper and using adjustable lowers to correct this. Does the tire hit the fender well as well as the bumper? If not, the issue is more the bumper sticking too far into the wheel well than axle placement.
 
Two complete sets, uppers and lowers out there now. I know Layton has his installed, no word if the second set is installed yet. I believe Layton is heading for Superlift with his this weekend.
 
Second set is going on tonight....then taking a trip out of town to test everything out on Friday. Thanks, Stan.
 
Correct. Uppers and lowers installed pretty easily. Leaving for superlift Thursday morning. Should be a fun weekend
 
I got the upper and lower arms on last Thursday. Took it to CA and put approximately 150-200 offroad miles on them. Mostly high speed stuff, with a few chances to flex the rear axle, substantially. I did reuse the Toyota hardware and did not have any issues with fitment. Will probably go to the 9/16 when I get the time because it would actually fit even more snug, but that being said I did not get any noise or any ill effects from the Toyota (metric) hardware.

I did notice that the rear did have a new (more) "range of motion" when completely flexed. Never, with either of the tires sizes I have run (295/75/16, 295/70/18) have the tires ever rubbed my rear 4x4 labs bumper when fully stuffed. Well, now they do and I can see that it will be pretty easy to shave a bit off the bumper to accomodate. I will try to put a couple pics up, soon. These arms (the johnny joint) definitely do let the axle flex more.

I am impressed with the quality and these look like they will hold up in the rocks, nicely.

Thanks

Chris

^Cool. Thanks for the update. I'm looking forward to ordering these. I've had to put it off longer than I wanted. Did you notice any change in ride quality?

Flexed What????


I send you this pic along with some of the others. It was crazy how much more he flexed over mine. If I hadnt just installed the Slee HD arms, I would buy these....
 
Nice picture! Is that the drop off at The Slot?

^^^ he runs L shocks right? They may be longer than your current shocks. I haven't touched my bumpstops yet on 33's and it flexes very, very well.

Yeah. We both have the extended 80 series sway bar links. But he had the "L-shock" I have Radflo's. He ordered some extended Radflo's that he hasnt installed yet. His rear bumper being more high clearance than mine also gives more of an appearance of even greater droop.

For example: Not the same spot, this is one of the lines at the Diablo Drop-off and higher camera angle:

Yes. It was really tore up! You could tell alot of people had been driving up it.

I didn't notice any particular change. Anything has to be better than 207K mile old bushings. My overall ride is much tighter, but there had been other new stuff installed also.
 
Links performed well at Superlift. New links combined with new Radflo 2.5s and extended rear sway bar links made the rear end feel a lot more in control, stable, and flexy.
 
Glad to hear that you guys are happy with your new links. Thanks for putting them to the test so fast.
