Key Features

• 12% Larger Adjustment Threads: Increased thread diameter compared to OE adds strength where bending loads are concentrated.
• 4140 Chromoly Inner Tie Rods: CNC-machined 4140 chromoly inner tie rods and ball studs deliver substantially increased strength and durability compared to factory components.
• Forged Steel Outer Tie Rod Ends: Heavy-duty forged steel construction provides increased strength while maintaining an OE-style profile for factory and aftermarket wheel clearance.
• Metal-on-Metal Joints: Durable metal-on-metal bearing surfaces replace the factory plastic inner races, with greaseable joints designed for extended service life.
• OE-Compatible Geometry: Maintains factory operating-angle range and is designed to clear factory wheel diameters and offsets, as well as most aftermarket wheels.
• Additional Protection: Includes inner tie rod boots to help protect the steering rack from dirt and debris.
• Limited Lifetime Warranty: Backed by ICON Vehicle Dynamics' limited lifetime warranty.

Overview & Key Benefits

The ICON XD Forged Tie Rod Kit is a heavy-duty steering upgrade engineered specifically for 2010–2024 Toyota 4Runner and 2010–2014 Toyota FJ Cruiser models.

Larger tires, technical terrain, and repeated off-road impacts can place significantly greater loads on factory steering components. ICON addresses this known weak point with stronger materials, increased dimensions, and durable metal-on-metal joints designed to provide increased steering confidence in demanding off-road conditions.

The Engineering Advantage

Factory 4Runner and FJ Cruiser tie rods were designed around factory tire sizes and normal road use. When larger tires are added, the additional leverage acting on the steering system increases the loads transferred through the tie rods. Combine that leverage with repeated impacts from rocks, ruts, and technical terrain, and the OE components can become a limiting factor.

ICON XD Forged Tie Rods are engineered specifically to strengthen this critical connection.

The inner tie rods and ball studs are CNC machined from 4140 chromoly steel and utilize metal-on-metal bearing surfaces in place of the factory plastic inner races. Adjustment threads are 12% larger in diameter than OE, increasing material where bending loads are concentrated.

On the outside, forged steel tie rod ends provide additional strength while retaining the factory tie rod profile. This allows compatibility with factory wheel diameters and offsets along with most aftermarket wheel combinations. Heavy-duty metal-on-metal joints maintain the factory operating-angle range and incorporate grease zerks for serviceability and extended component life.

The result is a stronger, serviceable steering upgrade designed for Toyota owners running larger tires and tackling the type of terrain where factory steering components can reach their limits.

Fitment & Technical Specifications

Part of a Complete Steering Upgrade

For vehicles regularly subjected to larger tires, rock crawling, and demanding off-road terrain, steering strength should be considered as a complete system.

ICON XD Forged Tie Rods strengthen a critical connection between the steering rack and wheel while maintaining the geometry and clearance required for proper suspension and steering operation. Pairing upgraded tie rods with appropriately engineered steering and suspension components helps ensure the complete vehicle system is prepared for increased off-road loads.
