It would be great if SOMEONE did start making these extenders or spacers locally. The quality of the metal ones I received last year were lacking quite abit... for what they cost. They weren't trued on the inside ID (out of round) and they were made out of soft steel. Even if someone DOES finally field a "complete spring lift kit" for these newer trucks, there will still be plenty of people who cannot afford a grand-plus lift but could and would buy the "budget lift" components. I know from the perspective of local machine shop owners that they are extremely wary of lresulting liability issues on any part that they machine for vehicles.
