Product Description

The Synergy Mfg 8849-20 HD Steering Knuckle Kit delivers a premium upgrade for Jeep Wrangler JL/JLU (2018-25) and Jeep Gladiator JT (2020-25) owners building serious off-road or heavy-duty rigs. By replacing the factory aluminum knuckles with high-strength nodular-iron units designed for high-steer geometry, this kit improves durability, articulation, and handling under demanding conditions.

With the high-steer configuration enabling a flipped drag link and raised track bar mount, the 8849-20 helps optimize roll-center and steering geometry in lifted setups. The nodular iron construction and precision machining ensure joint life and structural integrity far beyond stock, especially in large-tire, long-travel or rock-crawling applications. Installation is bolt-on for the knuckles on Dana 30/44 axles and retains compatibility with factory rotors/calipers and many aftermarket axle shafts.

If you're upgrading your front end for larger tires, heavy off-road use, or want to eliminate a weak point in your build, the 8849-20 offers a rugged, high-performance solution engineered to last and perform. Combine with heavy-duty ball joints, upgraded drag links and track bar kits for a complete steering system overhaul built for extreme use.
