Electric Power Steering Kit for Toyota Land Cruiser Series 4 (BJ, HJ, FJ): The Complete Guide

The Toyota Land Cruiser Series 4 (BJ40, BJ42, BJ43, BJ45, BJ46, HJ45, HJ47, FJ40, FJ43, FJ45...) remains one of the most iconic and durable 4x4 vehicles ever produced. Sold on all continents, it owes its reputation to its robustness and exceptional off-road capabilities. However, it has a well-known flaw among all its owners: extremely heavy steering, especially when at a standstill or at low speeds. Here's how an adaptable electric power steering kit can drastically change your driving experience without altering your vehicle.

Why is the steering on the Land Cruiser Series 4 so heavy?

The Series 4 was marketed for decades without any power steering assistance. It was only in the very last years of production that Toyota equipped some BJ models with hydraulic power steering. As a result, the vast majority of BJ, HJ, and FJ vehicles on the road today still operate with 100% mechanical steering.

On a vehicle of this size, this translates to:

  • A steering wheel that is very difficult to maneuver when at a standstill or during parking
  • Real muscle fatigue on long journeys or off-road driving
  • Lack of precision that can affect driving comfort and safety

Electric Power Steering: A Modern Alternative to Hydraulic Systems

There are two solutions to lighten the steering of a Series 4: installing a hydraulic ram (an agricultural solution, bulky and prone to leaks) and the EZ Electric Power Steering kit, which is currently favored by owners of classic vehicles.

How does the kit work?

The kit is directly placed between the steering box and the steering wheel, just like the original steering column. An integrated potentiometer allows you to adjust the assistance intensity according to your driving style: softer in the city, firmer on rough terrain, or at high speeds.

Key Features of the Kit for Toyota BJ/HJ/FJ

  • No welding or cutting of the tie rods, steering box, or column
  • Reversible installation: the original column remains in place, a real advantage for restoration or future resale
  • Compatible with 12V and 24V, with an optional 24/12V converter available
  • Easy installation on the firewall, with 3 or 4 screws depending on your setup
  • Estimated installation time: 4 to 5 hours, with detailed instructions provided
  • No hydraulic maintenance required: no pump, no hoses, no leaks to monitor
  • Integrated safety features: in case of electrical failure, the steering returns to non-assisted mode without locking the wheel

Tangible Benefits in Daily Use

After installation, Series 4 owners unanimously report restored maneuvering comfort, reduced fatigue on long journeys, and much more precise steering without compromising the vehicle's off-road character. Unlike a hydraulic pump that constantly draws 3 to 4 horsepower from the engine, electric assistance only consumes a few amperes, only during maneuvers.

The kit is completely installed under the dashboard, invisibly: the controls, ignition switch, and original plastics are restored without any visible aesthetic modifications to the interior.

Should Authenticity of Your Vehicle be a Concern?

This is a question that naturally arises for collectors. The answer is no: since the installation is completely reversible and does not involve cutting the original column, your Land Cruiser Series 4 retains its full collector's value. You can always revert to 100% mechanical steering at any time.

In Summary

The electric power steering kit for Toyota Land Cruiser Series 4 (BJ, HJ, FJ) is now the simplest, cleanest, and most reliable solution to rediscover the driving pleasure of this legendary 4x4, without compromising its authenticity. Compatible with 12V and 24V, no welding, reversible, and approved: it's the modern upgrade that your Series 4 deserves.
