So I have been doing some reading and wanted to get some input on the whether or not it is absolutely needed to get an extension done on all the breathers on my X. Now granted I don't do a whole lot of water crossing, my X is lifted and sits on 33"s. But at the same point if I do any water crossing, how well do the stock breathers fair?
yes you should do it - there have been instances whereas the OEM breather failed (clogged) and the axle died an unfulfilled life
