does anyone know the stock jet size for a 98 trailblazer?i ordered a dg pipe&silencer,and a k&n
filter and wan't to know what sizes i'll need to jet it in.Trailblazer owners with aftermarket pipes what size main jet are you running?Any recommendations for a good clutch kit?thanks

 

I am running a HPD pipe and silencer with a 140 main jet. I believe I would go with a HPD clutch kit. Just call them up and tell them what you got they're real helpful.

 

how hard was it to put the clutch kit in?
