Outer Limits 4x4 Board

i have just bought a 98 sj80 sierra (detachable hardtop)
im looking to put a two inch lift on it but the back coils dont have the shocks threw them , when i have seen the lifts for it they all seem to have shocks for the back aswell whats the go ?

the front has struts, shock inside coil, the rear are separate coil and shock, the kits will have what you need.
