The Perfect Custom Lift Kit for Your Toyota Truck

At John’s 4x4, we bring decades of experience to each service we offer, so whether you’re in need of repair and maintenance services for your Toyota or you’re considering a custom lift kit, we’re the team to turn to. We love modifying Toyota’s, so no matter what you’re hoping to get out of your vehicle, our expert technicians will work with you to ensure that you’re ready to tackle whatever road lies ahead.

Let’s face it...Toyota 4x4s are fun, capable, and a ton of accessories and modifications are available. Because of this, Toyota 4x4’s get used differently, they perform differently, and they require different repairs. They also demand modifications to perform even better.

We love Toyotas too! We can help you with your Toyota 4x4 no matter what model it is or how you use it. In fact, Toyotas are our #2 highest volume vehicle here at John’s 4x4.

  • Toyota Repair - While Toyotas are some of the most reliable vehicles out there, they still require regularly scheduled maintenance and routine repairs. We can perform thorough inspections and tackle difficult diagnostics to ensure your Toyota is running in perfect condition.


  • Trail Toyota - For the Toyota owner that uses their rig to explore and run trails, we know how important performance and capability is to them. We not only install high quality aftermarket suspension, axles, steering, and protection, but we also perform custom fabrication to meet your needs. From gearing, to axle housing and suspension modifications, to chassis fabrication (ie. tire clearance) and extreme lighting and controller systems.


  • Overlanding Toyota - For the rig that explores and camps across this beautiful country in places not seen by most, we can make sure your vehicle is outfitted for storage, camping, rooftop tents and more. Specializing in suspension, we can build a suspension to bear the weight of that extra equipment and be capable on the trail.

  • Warranty - all of our repairs come with a 24k Mile / 2 year warranty.
  • Better than the dealership - we know how to make your Toyota 4x4 perform. Dealers know how to replace OEM parts. We know how to install and tune higher performance parts and equipment in your Toyota 4x4.
