KYB's are harsh riding and don't have much rebound control. They will make your springs feel a lot stiffer while driving. Use anti sieze on the u-bolt threads and torque them in equal steps. Recheck them after a few miles several times. They always seem to loosen up a little.

Be sure to lube the bushings of the new springs too. I always use synthetic disc brake caliper grease on the bushings, as it won't attack plastic or rubber and has all kinds of good slippery stuff mixed in it.

Here's a pic of my old ones. I ordered mine from a place that makes them for almost anything. They came with the longer bolts, the hardened washers and they fit perfectly. I can look up the name on my receipt, if you're not in a hurry.

Sorry for the delay. Here's the link
