72 GS 350 4 speed What is the recommended collapsed and extended length of front shock for a Viking coil over for drag race application ? They seem to range from 3.7" to 7.75" stroke. I would think that a long stroke would be the one as long as you get the full range of motion, but hay??? What length are you all running for springs and shocks? shock stroke Spring weight , 350 , 450, 550 LBs
