Anyone here know what the hell the differences are? I need to order a set and these are resonably priced and look almost the same to me. What am I missing?

 

SRC is a tube design that mounts to the frame on two points. I'm not sure if it is offered for the JK or not. The XRC is mounted to the OE tire points using 2/3 existing Rubicon Sliders mounting points as well as additional mounts to the body. We are running the XRC and it's been pretty tough and taken some really hard blows. Falling off a boulder and landing directly on the slider, etc.


Here's a pretty good article on the XRC Sliders.

The new ones actually mount to all 3 of the body bolts now. It was a design change, the XRC for the JK is actually a plate of steel that covers the pinch weld and has a bar that covers over the rocker panel.
