As the 4th Gen 4Runner ages, the factory steering rack often becomes a weak link, especially when tasked with turning 33-inch or 35-inch tires through technical terrain. Frequent failures include leaking seals and internal rack play, which are only exacerbated by the weight of armor and gear. This Toyo-Steering kit provides a shop-proven path to swap the factory unit for the much larger 2007-2021 Tundra steering rack. By moving to a full-size rack architecture, you gain the mechanical resilience needed for long-term reliability on and off the pavement.

Key Features

• Upgraded Internal Components: Transitions the vehicle to the larger rack bar and internal piston of the Tundra, designed to manage the high-torque loads of a full-size truck.
• Billet Aluminum Mounting: Features 6061-T6 billet clamps that replace the aging factory rubber bushings, eliminating rack movement and providing a more precise steering feel.
• Reinforced Hydraulic Lines: Includes custom-length, high-pressure braided stainless steel lines that adapt the Tundra rack ports to the 4Runner’s power steering system without modification.
• Maintained Steering Geometry: Specifically engineered to retain the factory steering sweep, ensuring that your 4Runner maintains its turning radius without binding or bump steer.
  

What’s Included

• (2) Billet 6061-T6 Aluminum Rack Clamps
• (2) Custom Inner Tie Rods (Engineered for Tundra Rack to 4Runner Outer Tie Rod fitment)
• (1) Steering Shaft Extension/Adapter
• (1) High-Pressure Braided Power Steering Line
• (1) Return/Low-Pressure Power Steering Line
• Complete Class 10.9 Hardware Kit

Pro Tip: For many 4th Gen owners, the factory rack is a when, not if failure point once mileage climbs. This conversion is the standard for 120-series builds planning to run 35" tires. While the front end is disassembled, it is the ideal time to refresh your Suspension bushings and check your Recovery points to ensure your rig is fully prepared for the backcountry.
