I have a 2000 Trailblazer 250 and was wondering what the stock gearing was on it and what kind of gearing could i put on it to get more speed on top end. I have the RCR stage 1 low to mid kit and want to get more speed on top end what will help to get more speed? Thanks

 

im not sure what the stock gearing is on the newer trailblazers but 12 teeth on the front and 34 teeth out back would be good w/ ur mods u have now but u may loose a little bottom end

 

Stock front is 11T, rear is 38T. If you haven't changed your chain, that would be a good idea. Go up on the front sprocket, or down on the rear to get more top end.

 

gearing on the tb's vary by the year....go to partsland and look. i no mine was 11/36 stock adn im running 12/34 but i wouldnt go 12/34 with your mods u wont have bottom at all. mine still wheelies with this gearing but mine makes a lot of power. i would just drop the rear to a 34 if i were u because going up one in the front is equal to about 3 teeth in the rear and if u drop the rear size u wont need a new chain
