I was really pleased with these. I got them for my Twin Detonator and they gave me the suspension travel that should have been there out of the box. I used 100mm shocks - Yeah Racing (#DP-1007TI) 100mm Damper Set (TI) for 1:8 Buggy (2pcs) -. You could use longer shocks but I think your dog bones wll be more likely to pop out and in my opinion if you only run on tarmac, jump a lot or run hot motors you might be better off with slightly shorter shocks.
