Shock extenders

[Maximus09]

Purchased this kit for my 2005 yukon xl with auto leveling air suspension. Suspension is stock. The directions of this kit says they are not needed for OEM shocks. I would assume they wouldn't hurt. Does any one have any experience with these shock extenders and should I throw them on?

I'm currently using them without any issues, have had them through some light trails, but know that they do restrict your travel. I'm replacing with 5100s asap
