I have Bilsteins on mine, like them alot, a great shock.
Autozone here had to special order them, but at no additional charge, arrived fast. $230 i believe for the set of four.
Install is very easy. i couldnt get the rears to compress enough to fit in, so i jacked to rear up as high as i could get it to lower the axle and its mounts to allow more room. Then after installing the top mount, i compressed the shock with another jack and slid the bottom in to its mounting holes.
