I originally ordered the diamond skidz for my LJ, but called Jeeperman. He made mine without the diamond plate and added addition structural support between the box tubing and exterior rail. He even refunded me $15 for not using the diamond plate! These are not extemely heavy. Wooden crate and all, they weighed 70 lbs when they arrived. If my memory serves me right, Savvy's aluminum sliders are approx 27 lbs per side, so the Jeeperman's are comperable. The only downside or plus side, depending on how you are looking at it, is that you are loosing some ground clearance under the rocker pannel. However, unlike tub mounted sliders, these protect the factory body mounts. If you don't want to drill holes in your tub, these are the way to go. If holes don't bother you, there is better stuff out there for you.
