With the DIY Slider Tube Kit you can add a rugged, DOM tube slider to your home-built or other manufacturer's rocker protectors.  This kit is the correct length to use with CJ-7, YJ, TJ, or any application of similar length.  The kit includes the slider tubes as well as the short tube supports to brace the center of the tube against the rocker, to do both sides of the Jeep.  We do not recommend welding them to the stock sheetmetal or to steel thinner than 1/8", with 3/16" being the ideal plate thickness to weld them to.  Installation should be performed by a certified welder.
