Shockworks is generally very high quality. I would imagine that the Xreas models have a slightly different bracket configuration than the non-Xreas. Sounds like it's time to replace those stock boards with something more substantial.
I have the shrockwork sliders on my truck. There are definitely heavy duty and made very well. Also the powdercoating they did was excellent.
I had a problem in the installation of the driver's side slider. The rearmost bolt was hitting a fuel line and the gas tank needed to be dropped to get the nut on the bolt and to move that fuel line. I elected to have the dealer finish up the install and it was another $200 or so.
I love them now that they're on.
Also, give Shrockworks a lot of lead time on your order. My sliders took about 3 months to get and the bumper took a lot longer. No complaints though, their stuff is well worth the wait.
