I purchased directly from Toyota the beefier under braces from the TRD version for my XSE V6. If you read any of the reviews of the TRD they usually compare that version to the XSE and its noted that the TRD version is much stiffer. Yes, the TRD has different springs and struts but I'm not getting those. I do have the TRD front and rear sway bars and sway bar bushings but haven't had time to install those yet. But, I wanted to post this for anyone interested. Direct replacement. Much more solid, and heavier...hoping the stiffness makes up for the weight. Pretty nice pieces. Relatively inexpensive and etched with TRD logo.
