The Flub-Tek Inserts have been designed around and are compatible with the new Proline Rock-Tek wheel weight system. Internally slotted x5 for the external hardware of the Rock-Tek system, our inserts use this to lock on tight and stay in place. The Flub-Tek Inserts come fully loaded with Forward Propulsion Technology and Double Barrel Profiles. These give you that smooth contact surface and superior conformity for unmatched grip and performance. Package contains 2 insertz. (Insertz are printed in our brand colors. They will come in one of 2 colors, random selection, green or purple) We recommend venting your tires when running our Performance Inserts. They are waterproof, temperature and mildew resistant, and designed to support without the need for sealed setups. ***All products are made to order. Please check the header on the main page for approximate lead times. Thank you for your support and patience - FlubRC
