Are the shocks the same for Z71 and LS tahoes?

[viv1d]

As the thread title says... Are they the same? Im about to add a 3 in spindle and 2 in coil spring spacer on my 2wd tahoe. I wanted to put the billstein 5100 but they are kind of expensive so I wanted to put these http://m.ebay.com/itm/331057560778?nav=SEARCH&sbk=1

Will they work?
