Does the RCR low end kit make a real big difference? How much better is it at hillclimbing?
For the trailblazer.

 

Big difference lets see: difference between night and day. Installed the low end pipe with clutch spring on the wifes 2000 TB. It makes it actually fun to ride now, as for climbing we ride the dunes and she's not afraid to follow now, due to lack of power before.
