Hi team my name is Peter I have a 2005 TD Sahara and I live in Perth WA. My rig is used for pulling my van and I have had a 3" exhaust system put on, a DP Chip from Berrima Diesel and had the transmission upgraded by Wholesale Automatics in Melbourne and it performs faultlessly. The only issue I have is that I want to upgrade the rear springs and fit airbags has anyone done this on a Sahara with the Self Levelling System (SLS).
