Will a rear fox shock from a 99' scrambler fit a stock 00' trailblazer?

 

yes it should!

 

Cool. I'm looking at a used one. The guy says it has about 400 miles on it and has no leaks. Anything I should look for when I go see it? What are these worth used..ballpark? Will I notice a significant difference vs. my stock shock?

 

I think you are looking at my shock on ebay. If your shock lower mount sits on top of the swingarm and not between it and the axle housing it will fit. You need to measure shock length because there are two length fox shocks and mine is the short one that is why I put the length in the description. I hope this helps. Short shock mount is 1/8" stamped steel and one piece, long shock mount is 1/4" thick and it is two pieces.
