Rotoflex King Pin Box Isolator

The Rota-Flex pin box is designed with a pivoting head and built-in rubber compound to reduce chucking and absorb road shock. However, when used with a SuperLite hitch, the rubber block inside the pin box may shift out of place during towing.

To prevent or correct this, PullRite offers a Rota-Flex Pin Box Rubber Isolator that secures the rubber block and keeps it in position. If the rubber block has already begun to slip, use Part #4446 to fix the issue by moving it back in place. For a proactive prevention, use Part #4447 before you start towing.

Each Rota-Flex King Pin Box Isolator is sold separately.
