Rota-Flex pin box isolator for SuperLite hitches. Fixes rubber block displacement during towing.
The Rota-Flex King Pin Box Isolator addresses a common issue when pairing Rota-Flex pin boxes with SuperLite hitches. The Rota-Flex pin box uses a pivoting head and built-in rubber compound to reduce chucking and absorb road shock, but during towing with a SuperLite hitch, the internal rubber block may shift out of position.
Part #4446 is the corrective solution: if the rubber block has already begun to slip, this isolator moves it back into place and secures it for continued reliable performance. Each isolator is sold individually.
