about 20k-30k old.

 

Oh they will be fine. They last a whole lot longer than that.

 

think ill be replacing them anyway, dont the uppers use stock bushings? The LCAs are getitng new bushings by default because im getting adjustable LCAs so they are brand new arms and come with bushings on them.... But do the Uppers use stock bushings or what? I think im going to replace these mine as well

 

Depends. I think the superflex kit has stock bushing on axle end, and superflex joint on other end, while the other control arm has both stock bushings in both ends. Call RE and see if they are indeed the regular oem stock bushings. Based on the pictures, they look exactly like the bushings i just replaced on my axle end.

 

Yeah I emailed them, but I might give them a call or just order some. Another thing is track bar bushings, those are gonna suck aren't they?

 

the 1600 or 1660?

 

uhh i have no idea? i have a rubicon express 4.5" lift... any idea which?

 

Does it have a new trackbar bracket with it? or just teh trackbar alone? the 1660 trackbar uses a bracket. They may both be built the same. I dunno. It should be fine considering the kit is still new.

 

damn i dont know, i would check but im 90 miles away from it untill christmas...

 

now THAT sucks.

 

The RE 1600 will not fit the after market frame bracket it requires the stock factory brackets. The RE1660 uses the RE frame bracket and has a different johnny/heim joint then the RE1600. The RE 4.5 kit comes standard with the RE1600 track bar. The axle side bushing on the 1600 and 1660 are the same the only difference is the johnny/heim joint.

 

poly or rubber bushing? looks like poly.

 

axle end is poly for sure..

 

hmmm looks like ill need to check this out, but im thinking i have the 1660. Actually im pretty sure because i dont hink mine has an aftermarket upper track bar bracket

 

1660 requires the bracket. 1600 doesn't. You probably have the 1600.
