As the title states, I have a 4.5" lift, and I'm going to be buying the rustys long arm kit with the crossmember from someone who got it with their Rusty's 6.5" lift kit. I can't find instructions anywhere, but at 4.5" what length should I set both upper and lower long arms to? Thanks.

 

get the axle centered in the wheel opening with the lowers and shoot for about 5-7 degrees of caster by adjusting the uppers.

 

So the lower arms won't necessarily be adjusted to the same length?

 

Also, how do I measure the caster? I know what it is, I just don't know how to set it right.

 

Get a degree finder gauge an measure it with the gauge on top of a knuckle

 

Okay. I think I understand. Where on the knuckle should I set it? The top part of the c?

 

Also, should this be done with my adjustable track bar on to keep the axle in place? Or do I adjust the long arms by themselves and then install the track bar and adjust it accordingly?

 

?

 

Is your track bar already adjusted for your lift? If so leave it be and adjust your caster.

 

No, I haven't installed it yet, I decided to wait until I go from 3-4.5" of lift.

Ok, install and adjust your long arms. You shouldn't have to mess with your track bar.
