Fits select 2007-2018 Jeep Wrangler JK and JKU models.

This Synergy Manufacturing Heavy Duty Single Plane Tie Rod End is engineered specifically to eliminate "tie rod flop" on JK steering systems. Unlike standard tie rod ends that can rotate on a ball-and-socket axis, the single-plane design restricts movement to a single axis. This prevents the tie rod from rolling forward or backward while maintaining the full range of steering articulation required for off-road use.

Built for durability, this end features a metal-on-metal bearing surface that is fully greasable to ensure a long service life and consistent performance under high loads. It is an ideal replacement or upgrade for enthusiasts running oversized tires or heavy-duty steering components.

  • Manufacturer Part Number: 4139-L
  • Thread Pitch: 7/8-18 LH (Left Hand)
  • Design: Single plane to prevent steering component rotation/flop
  • Construction: Metal-on-metal bearing for maximum durability
  • Greasable: Integrated zerk fitting for easy maintenance
  • Includes: Tie rod end, castle nut, and cotter pin
