My brother told me his 2013 Tahoe was at Sears getting serviced and fell off the lift. It damaged the running boards and doors pretty good. 4K in damages so far. It makes me want to get sliders because human error is a possibility in all things. My question... 4X innovations sliders seem to be the most affordable compared to CBI and Out Door Logic. Is there a reason? I really like the tire kick out that 4X has but should I save up for one of the others if they are built better? Not knocking 4X just wondering why they are so much less. Also if anyone has a lead on sliders for a 2013 Tahoe for my brother feel free to chime in so this doesn't happen to him again. Thanks in advance.
