ZF Lemforder offers a diverse line of Tie Rod and Tie Rod End configurations to serve a wide range of environments in on-highway, off-highway and construction vehicle applications. They are available in either Greaseable or Maintenance-Free models -- both of which utilize a micro-finished, heat treated, steel alloy, full-ball stud design that allows optimum angulation for a superior range of motion. A premium boot seal in both models protects the ball socket from dirt, water and other harsh contaminants. Finite Element Analysis is conducted to study stress points to ensure that the quality standards for all ZF Tie Rods meet or exceed OEM performance requirements.
