Product Description

The Synergy Manufacturing 4163-L is a heavy-duty, metal-on-metal replacement tie rod end designed for the 2018-2026 Jeep Wrangler JL and Gladiator JT. Engineered to solve the weaknesses of the factory steering joints, this rod end is a critical component of the Synergy High Performance Steering System. It features a robust sintered metal bushing design that provides a far more durable bearing surface than the plastic or nylon races found in OEM parts. This makes it the ideal choice for Jeep owners running larger tires and navigating technical terrain where steering loads are significantly increased.

Every aspect of the 4163-L is built for longevity and performance. The 4140 steel stud features an oversized shank to prevent snapping under extreme stress, while the 1018 forged steel housing provides a rigid foundation for the internal spring-loaded bearing. This spring-loaded design is essential for off-roaders, as it automatically takes up any internal wear to keep the steering feeling tight and responsive throughout the life of the joint. Fully greaseable and protected by a high-grade NBR rubber boot, this left-hand thread joint ensures your Jeep's steering remains precise, whether you're on a cross-country highway trip or a rocky mountain trail.
