The wise one answers:

I've now got standard shocks on my runner, but with an added spring on each one. Under the shock body around the shock piston rod. Just to keep the car looking standard, but getting rid of the ever so strong torsion bars/springs. But, in the past i've used various Tamiya shocks..standard black plastic ones from a TA03. Expensive hi-cap one's they use on the front of an Egress. There's many that will fit and cheap one's too.
