We specialize in Rock Sliders. We have three styles of rock sliders that can be built to your specs. Or if you have a style in mind we don't have, we can work with you to build exactly what you want - likely at no additional charge. The Rock Whores are my favorite and best seller. We build each set of sliders using a jig for exacting fit and tolerances. We also weld, grind, and polish the end caps for a professional fit and finish. Included in the price is a complete set of grade 8 bolts, lock washers, and flat washers for the install. Oh, and shipping is included as well. Check out the DPI site for more information. Or email firstname.lastname@example.org with questions. Thanks for Looking!
