Offroad Trailblazers and Envoys

Ground Clearance/ Frame Clearance/ Slider Clearance

Dumping ground for offroad Trailblazer or Envoy general discussion.

I plan to measure these tonight with the 34's and and with the Pro Comps.

I would love to see everyone elses numbers for this. Measure frame clearance in line with pillar between the doors and slider clearance there as well. Prolly measure slider clearance from lower bar and outside upper bar. Also measure ground clearance from front edge of oil skid. That should help give us similar numbers to see what is what.
I hate to advocate weird chemicals, alcohol, violence or insanity to anyone...but
they've always worked for me.

From memory I know that my stocker is 9" from frame to ground. Do you want the other measurements for reference?

At the moment i do. I am trying to decide which way to go for the next 6 months or so. I can add another rear spacer or I can drop out the front shim. I need to replace balljoints or may just keep tires rotated if i am gonn rip out the whole suspension anyway and say the couple hundred from the joints for the sas. It was 14 to the tie bara across the frame, which is horseshoed BAD now, but it was probably closer to 14.5 to the actual framerail.
