I have just ordered the iron rock rock link, 3 link system. While I am installing that, I want to upgrade the upper axle bushing bolt size from 10mm to something larger. I have found two options but unsure what to go with. This is my DD but sees trails on the weekend. Road noise/harshness is not really a problem either.

Those are the two I am deciding about, any input would be great. Thanks

 

did you get the 3 link or the radius arms? You can upgrade the 3 link, but the funky castor adjuster on the radius arms makes bolt size upgrade hard to do without losing that adjustment capability.

 

I got the legit 3 link one so no funky castor piece.

 

If you are going three link, like I have, then you will need something tougher than the rubber bushing. Right now I have a poly bushing there. The rubber bushing is not up to the job with only one to absorb the rotational forces. I have found that on the rubber factory bushing a 3/8" works better and 9/16" on the lowers is better there. On the machined flex joint, you will have to stick with what they give you

 

Out of the 2 you posted, one is poly, one rubber. That said, Currie is a well known company, unlike the other you posted. THAT said, Currie offers poly joints while the other is rubber. From the 2 posted, you need to make a decision. Poly joints are stiff, but noisey. Rubber is more like factory, and a little more forgiving, much quieter and a better ride. Won't last as long as poly. So, decision time, better ride or durability?

Personally I prefer rubber over poly. Better ride wins here, but Currie is a great company. Expensive, but reputable. You need to make the call.

 

Im trying to decide which one would be stronger and better for the 3 link. Being it's only gonna be the one upper mount I'd sacrfice ride quality for the stronger joint. The rubber is 1/2 so the bolt size is good but if it's gonna be going bad quicker id rather the Currie.

 

This video was meant for you.

 

Watched his video on the long arm install and then saw this lol. Got the arms in and got that bushing. works great and looks crazy strong. Thanks!
