TMR's Steering Clamp is THE answer if you are running a tie rod that measures 1.5" diameter.
Running a traditional steering stabilizer? Simply use the smaller 1/2"-20 tapped hole. Running a ram assist cylinder? Simply use the larger 5/8"-18 tapped hole.
Since the clamp is tapped for both sizes it's modular allowing you to change your system in the future without the need to purchase a new clamp!
