Frequently Asked

Our Void Extreme knee sliders contain a total of 58 spark inserts per pair, putting them among the most loaded sliders on the market. Once you hold these knee sliders, you'll feel the weight and quality that you won't find anywhere else.
Absolutely. Our knee sliders come with custom-made black hook-and-loop attachment with a premium soft-touch finish for a secure and stylish fit. This allows you to attach them to any leather suit with standard hook-and-loop patches. Simply fix the sliders onto your suit, and you're ready to ride.
Many competitors cut corners to save money. We don't. We pack as many spark inserts as possible to ensure maximum performance. Our proprietary construction prevents them from burning out or falling out prematurely. The result: smooth surfaces, premium hook-and-loop with laser engraving, and a build quality you can feel the moment you hold them.
Lifespan depends on riding style, surface, and pressure. With proper use (max 4 seconds grinding, then 5 seconds cool-down), the sliders will last you many sessions. The body is extremely durable and the spark inserts are deeply secured for long-lasting performance.
Each order includes 1 pair (2 pieces) of Void Kneesliders with pre-applied black hook-and-loop attachment. The sliders are ready to attach right out of the box, no additional tools or preparation needed.
