the hood hinges on 07+ are hydraulic hinges whereas 99-06 are mechanical spring hinges...has anyone made the conversion to hydraulic on the 99-06? LMC wants ~$20 for each hydraulic hinge....just wonderin if anyone else has done it yet

 

I'd like to. Looks cleaner under the hood IMO.

 

that's what i'm thinkin...and LMC show's the breakdown that makes it look like it's the same setup just that the hydraulic ram mounts to the lower arm

 

I like the spring hinges much more. They don't wear out.

 

On every tahoe I've seen, they have a hydraulic dampener in the center that sticks out like a sore thumb in addition to the clock springs for lift assist. And my 2010 Sierra only has the springs on the hinges.

True.
