TB Parts corrected the problems associated with the 2007 and older OEM output shafts with our own heavy duty version. If you are upgrading or rebuilding your 2007 and older engine, its highly recommended you replace your OEM output shaft as they are well known for failing. Ours also works on the 2008 and up models as well but is only needed as a replacement or if some extra strength is desired for a built up big bore engine. We put this output shaft in every full engine rebuild for cheap insurance!

** This will fit all KLX/DRZ110's but it is only needed on 2007 and older models **

Important Notes:

Installation requires complete engine dis-assembly. Therefore, we highly recommend a professional technician install this HD ouput shaft.
