Very broad question. What "offroad" stuff specifically???

There's almost nothing left, SPECIFICALLY for the VX.

Sliders and diff guards are still available from Rocky Road. I have the SuperSliders and Mav just installed the same.

Rocky Road Outfitters

A few places still sell the GTS headlight and tail light covers and the WeatherTech window visors.

For other items, there may be some stuff that can be modded to fit. (Like the Westin Bull bar needs the custom made mounting brackets).

Use the search function on the items you're interested in and you'll find plenty of info already posted.

Oops, forgot about Indy4x.....braided brakelines, tie rods, etc...
