Should We Modify our 100 Series Land Cruiser
The good news is that the 100 Series Land Cruiser is ready to drive straight out of the box, but you know you want a little more from your Land Cruiser, so Land Cruiser 100 Series modifications are certainly something to consider. While a modified Land Cruiser 100 Series is more about your driving style and preferences than it is about the factory performance of the LC 100, everyone wants to do a little something to their Land Cruiser to personalize it for themselves.
When asked in an informal online survey, a majority of people said that they wanted to do moderate changes to their 100 Series to enhance the overall performance both on the road and off the road. The next group of people was the die-hard rock crawlers who wanted aggressive modifications, so they could run longer distances and run rougher trails. The more extreme drivers only made up a small portion of the people asked, and they wanted to climb over very extreme terrain like you would find at the tops of mountains. Only a few wanted a modified Land Cruiser 100 Series because they did not like its appearance.
Some of the modifications available for the Land Cruiser 100 Series include:
- Roof rack
- Suspension upgrades
- Lift kits
- Bumpers and winches
- Running lights and grilles…and more

What Wheel Fits the Land Cruiser 100
The Land Cruiser 100 wheel bolt pattern has been 5×150 with OEM 18- and 16-inch wheels for its entire lifecycle; however, you can fit 17-inch aftermarket wheels on the 100 Series. All LC100 wheels are 60 ET and 110 DIA.
Because the Land Cruiser 100 Series has an independent double-wishbone front suspension, it is easier to make wheel improvements on it than previous Land Cruiser models with their rigid axles. The IDW keeps the center of gravity low, and it has smaller and lighter weight suspension parts giving tires better response time. All wheel changes will change its overall appearance.
When looking for replacement wheels for your LC 100, there are a lot of options on the market. Low-profile wheels are some of the most popular choices when it comes to making changes to the wheels on your Land Cruiser. Since wheels affect other factors like traction and performance both on- and off-road, we wrote an article to help you understand the driving changes that happen with a wheel change. Keep in mind that the 100 Series Land Cruiser wheel bolt pattern is 5×150.

What Steering Wheel fits the Land Cruiser 100
You will find many styles and sizes of Land Cruiser 100 Series steering wheels, and you should choose your new Land Cruiser 100 steering wheel based on your driving preference. A smaller steering wheel is good for racing because you do not need a maximum turn, while a larger wheel requires less steering effort.
The standard-size steering wheel on the LC 100 is between 14 (355 mm) and 15 inches (381 mm). You can interchange the LX470 steering wheel with the LC100 wheel.
Is a Front Locker Necessary on the 100 Series Land Cruiser?
Whether or not you need a 100 Series Land Cruiser front locker depends on where you intend to drive your LC 100. For regular, everyday driving, the Land Cruiser front locker is not necessary. However, if you are planning on crawling over rocks, then you will be glad that you installed one. It will give you the extra traction that you need to scramble over rocks and up steep inclines. It will also be very helpful for powering through mud and other slippery conditions.
If you don’t plan on tackling anything more challenging than your driveway in the winter, then you probably don’t need to install a front locker. A-TRAC does a good job of getting you to and from places.
Ultimately, the key to the best traction is to have the proper tires and drive at slow speeds when climbing.
