Hey, you can look at these:
1/8 buggy/truggy front Shocks (the rears might be a little long)
Proline 'PowerStrokes' (you can still find them on ebay)
UE 'Supershocks' (again, you can look on ebay)
Have a look at this thread...
What are the strongest E-Maxx shocks?... some good info here.
hope this helps
