The 5th Gen 4Runner is a premier overland platform, but when outfitted with heavy armor and 35-inch (or larger) tires, the factory steering rack becomes a significant liability. Repeated stress on technical trails often leads to internal rack failure or excessive play in the mounting bushings. This Toyo-Steering kit allows you to retrofit the larger, more substantial 2007-2021 Tundra steering rack into your 4Runner, providing the mechanical strength required for heavily loaded rigs and aggressive terrain.

Key Features

• Tundra-Spec Internals: Upgrades your steering system to use the full-size Tundra rack bar and piston, which are designed to handle significantly higher torque loads than the stock 4Runner components.
• Rigid Billet Clamps: Includes 6061-T6 aluminum mounting clamps that eliminate the movement associated with factory rubber bushings, ensuring your steering input is delivered directly to the tires.
• Vehicle-Specific Hydraulics: Provided with custom high-pressure and return lines to connect the Tundra rack ports to your 4Runner’s power steering pump with a factory-style fit.
• Optimized Geometry: The kit is engineered to maintain correct steering sweep and pivot points, preventing bump steer and ensuring your suspension cycles cleanly through its full range of motion.
• Heavy-Duty Hardware: Uses high-strength Class 10.9 fasteners to secure the rack, providing a reliable foundation for your front-end steering assembly.

What’s Included

• (2) Billet 6061-T6 Aluminum Rack Clamps
• (2) Custom Inner Tie Rods (Tundra Rack to 4Runner Outer Tie Rod threading)
• (1) Steering Shaft Adapter
• (1) High-Pressure Braided Steering Line

Pro Tip: The 5th Gen 4Runner is a heavy vehicle once fully built for travel. We consider this a no-brainer modification for anyone planning to tackle the Rubicon or long treks through the BC interior on 35" tires. While you're in there, it’s a great time to inspect your Suspension for wear and ensure your Recovery points are easily accessible.
