Re: Bilstein 7100 series...
Weazle's correct, the Fox's are pretty easy to rebuild. They also have a larger diameter shaft. But I'm real happy with my Bilsteins. I'm going to have to talk to Jeremy, because he charged me more than $130 for my 7100s. You might want to think about going to a short body 14 rather than the 12. These shocks aren't listed in the Bilstein materials, but they will make them. It's basically a 12" body with a 14" shaft. That gives you more available shock at the same compressed length. Even if you don't need the extra extension, it leaves more rod in the body at full droop and that makes it less likely you'll bend a shock.
There's also a guy in Santee, I think it's Baja Fabrications but I don't have his card handy (you can get his name from Shane at Bilstein), who knows a lot about Bilsteins and works on them at very reasonable prices. He charged me $25 labor + parts, and gave me a break on the parts to work on a couple of mine.
Have fun, george.
