K&B 7.5/11cc Brass Liner RC Car All made from Billet 6061These are direct replacement liners for the teflon tube that comes with these lower units. These liners last much longer and have less resistance. These are for the K&B lowers only, and may require slight tweaking bending by hand to make them fully seat inside the liner cavity. They may work with Lawless, but may need to be slightly bent by the user to fit in the liner cavity.
