I have Katzkins in my Ram and I did the install and they fit like a glove and have held up REAL well, considering they are perforated yelllow leather centers and haven't exactly been babied. The drivers side has seen better days, but it still looks "ok".
There are typically two different Katzkins kits, one is typically $650 and the other $1200 give or take. The cheaper of the two uses vinyl for the bolsters and only leather for the bottoms and backs, and honestly that's the way to go.. Leather in high traffic areas like bolsters does not hold up well.
