question on picking shock by length
 

Today I measured for shocks for the rear. Since I recently finished the rear stretch I need to get some new shocks for it. The collapsed length is 19" and the extended length is 29". So my question is which shock should I choose if the measurements I took are not measurements offered by bilstein. I don't want to pick something that will limit suspension travel. Attachment 340009
One more thing to add I haven't made new shock mounts but It should be a two inch difference from where I took the measurements.

4.5" lift? get either the 10 or 11" shocks. remember that the 5125 are eye mounts, so you need a stem eliminator up front that will drop your upper mount 1.25"

i would like to know which ones you go with as far as valving is concerned.

255/70

It's not really 4.5" lift anymore with the compcut and chevy leafs and I will be making new top and bottom mounts for both front and rear.
