Yes.
But in order to install new springs in the rear you have to both dismantle the rear swaybarlinks and the rear driveshafts (from the diff flange).
Otherwise you risk breaking the rear swaybarlinks and worse the rear driveshaft seals.
The only think you'd be doing double is the lower rear shock bolt.
