I didn't put any miles on them. haha
I'd just about finished putting my RCX lift on and bought these on ebay from a guy that was removing the lift from his 02 2500HD. While they were on their way, I tried aligning the front end myself and figured out that with a 1/2 ton lift on a 3/4 ton, I'd need to crank it to the bump stops to maintain proper camber as there's not enough room for adjustment without notching the frame in four places. So before these even got here I'd decided to say the IFS lift and buy a Dana 60. I'll probably start ordering parts for a SAS sometime this weekend.
They are indeed beefy as hell, and a lot heavier than I expected them to be.
Shipping to 99506 is $12. Looks like you'd need to remove your trac bars.
