RKraiza said:f youor n that much need of a 31/4 box. go to advanced auto. buy the 31/4 lares box not the cardone! lftme warenty and t seems to be worng so far. To get the chucleheads to order you the right box, tell them you need a box for a ram 2500 4x4 with a gas engine(not the 8800 gvw heavy dana axle) If you want to make sure, look up the box for the diesel 2500 4x4 witha 88oogvw axles. it'll be a different part number if they looked them up right. hope this helps
