Shocks/off road-wheels

[geo]

Hi,
I'm currently in the process of building a off-road robot. I was wondering anyone could provide some places where I could get suspension shocks/ off road wheels(~5 inch in diameter). I couldn't find anything useful with Google.
Thanks

Try robotmarketplace.com and maybe check out gokart parts.

vex sells 5 inch diameter wheels, idk how good outside on tough conditions they would be though, in a servo magazine there was a vex all-terrian robot so it must be possible
