yes they are, all wk (2005-2010)
Here are 3 threads, the first 2 are how NOT to install them, the 3rd is how you DO have to install them (in chronological order). Basically, you just have to exchange the cushions, not the electric parts (unless you have a laredo without electric seats; in that case, you will have to look the how NOT to install):
How NOT to install 1:
Installed srt-8 front seats.
How NOT to install 2:
New SRT8 Seats.
How to CORRECTLY install SRT seats:
HOW TO: 08+ SRT8 seats in 05-07 WK
All these are 2008-2010 SRT seats into 2005-2007 Grand Cherokees. I bought 2007 SRT8 seats to put into a 2007 WK, and I will follow Svenskajeepguy´s procedure, but I´m too lazy to even take the car to my friend mechanic.
