We modeled the geometry of this steering after the stock Y-Style steering.
The Tie Rod is made from 1-3/8 4130 Chromoly steel and is Heat Treated for maximum strength. Both parts are finished with an abrasive-resistant powder coat finish for maximum durability and corrosion resistance. The Synergy MFG Heavy Duty Steering Kit for TJ/LJ, XJ, ZJ, and MJ models is a larger and stronger, bolt-on replacement for stock steering.We did this for a couple of reasons.
