The 16-17 Round sliders are built with 1.75in .120 wall round tube steal. DeMello Off-Road tube sliders use a "L" shaped bracket to capture the frame for both our weld on sliders and our bolt on sliders.
Our sliders use all grade 8 hardware and require minimum drilling. Bolt on sliders can be bolted on with out drilling but if you plan to use them as sliders we recommend drilling the extra holes. If you just want a step or use as door ding protection then using the factory holes would be sufficient.
We also offer a powder coating option for our sliders. Powder coating is not indestructible and can wear overtime. The longevity of the powder coating depends on the environmental conditions and use. powder coating carries no warranty.
Please note, that powder coating is an option and holds no warranty from defects and damages. It will not protect the bumper from scratches, rust, trail damage, street damage or other. We do our best to ship the product to you with out damage to the powder coating but it has no written or other warranty.
