Leveling kit question

The higher you go the stress on equipment grows exponentially.

“Change my mind”

The lifts don't put components out of design parameters. Bump stops make sure of that. They just make things like ball joints, CV joints and boots, and tie rods ride primarily at the upper end of that spectrum all of the time. Because of that, you'll have premature wear. As far as how much....no one can tell you. Major components won't be failing though, so you've just got to be okay with replacing the simple things more often, and you need to make sure to keep the correct spec clean grease in those joints.

On that specific kit, I don't really care for the "fabricated" rear blocks. I'd rather cast or billet blocks, and I'd check to make sure that hardware is grade 8. I'm anal about stuff like that though
