Stratos light truck suspension seat (LTSS) with D22 navara rails
Bought this for my D22 navara a few years ago for $2200, car was only used for trips only and would say definitely less than 10000km in this seat, and is still in very good condition. It does help with posture and back aches, has adjustable air pumped lumber support. Can be used with different 4x4s but you will have to buy the railing to suit from stratos
