    Bilstein or Rancho shocks for smoother ride?

    2004, X, 4.0, 5 Speed. This is my daily and I live in the New England area so pot holes are a norm. Looking for smoother ride. Narrowed them down to the two brands I keep seeing. Of the two (and only the two please) what's your choice, Bilstein or Rancho?

    Jeep TJ clutch change

    Hi guys, My TJ was getting harder to shift when it was warmed up. In start stop traffic, and in lower gears. I took it to my local shop and they said I need a new clutch. The car has 320km on it and I don’t know when the last owner did the clutch so I think maybe they are right. I just wanted...

    I need to replace the fuel pump I believe in my 2005 4.0l tj. I get hard starts sometime when it sits for a while and after filling up the tank starts fine throughout the day other than that.

    Hey guys, I've got an '06 TJ with 4.0, and 6 speed. It's done this odd thing where it cuts out under acceleration since I've had it. It would flash the CEL but never store a code. If I backed out of the throttle, it would continue to run, but if I kept on it, it would die. Over the two years...
