Thanks for all the good words on my Rappers, I just want to say that I designed these using dies made from a NOS rocker panel, So the fit is as good as you can get. I used a 2 piece interlocking design to insure a good fit if tolerances are slightly off. As for the side tubes I started adding these to the 1/4" Rappers by request, The main reason people wanted the side tube was for side protection (when you slide into a object) it will be less likley to damage the door, and a step function for the wife ;D The tubes are high enough that they will not usually be the first thing to hit, but if they do I am confident that they will hold the stress applied to them. There are only so many ways to reinvent rocker protection, I am sure all the vendors rocker protection serves the purpose they are intended for. I feel the full back panels on mine with the interlocking design just give you that much more insurance. I have sets of these on 3 bronco that have all seen hard wheeling and they have never substained any damage. There are several choices for people to make in the rocker protection department, styles and personal preferance.
