1. Bilstein Touring shocks
2. Bav auto rear shock installation kit
3. rear shock mounts.
But if you replace your rear shocks w/ gas shocks you should also replace your front ones at the same time. Don't mix gas and automatic shocks.
If you don't want to do this, just pick up some replacement Boge shocks and shock mounts.
And don't forget to get an allignment.
