Our replacement adjustment screw kits will help get your RV's trailer brakes back to operating in no time. As an exact-match component, this product will install just like your original equipment. This is a replacement, adjustment screw kit that's compatible with Lippert electric brake assemblies. Please reference your original equipment label before purchasing.
