RPM's ESC Cage for Traxxas XL-5 & XL-10 ESCs is the most effective, durable and best protection possible for your speed control. We eliminated the use of the two undersized mounting tabs on the ESC in favor of a complete cage system that solidly locks your XL-5 / XL-10 in place. By completely surrounding and capturing the XL-5 / XL-10 ESC, damage from broken tabs and ejection from the vehicle has been completely eliminated.The RPM XL-5 / XL-10 ESC Cage works perfectly even if one or both mounting tabs have already been broken or cut off! Now there is no reason to rely on unpredictable adhesives or zip ties to protect and retain your speed controller when our ESC Cage will lock it in place with 100% confidence each and every time!Each RPM ESC Cage is made from incredibly strong, ultra lightweight blend of engineering grade nylons. RPM molded products are made with pride in the USA!
