How do Off Road Beasts Come to Life?Our Build Process in 3 Easy Steps

Every Custom Build or Restoration has a simple three step process we follow to ensure your custom 4x4 or restoration project is completed to your total satisfaction.


The customer always knows what they want from their vehicle. We strive to bring that dream to a reality by sitting down and consulting on an approach to bring the concept to a reality.

Design and Build

RSO Breaks down the vehicle to inventory everything that is needed to get the Job done. Then we get to work on designs for your approval.


When the vehicle is complete, it is tested and delivered to the customer. Great care is taken to make sure the vehicle is in perfect condition upon delivery.

Rock Solid Off Road, also known as RSO Performance, has been building custom Toyota FJ40's, Jeeps and various other off road vehicles since 1999. We specialize in building custom rock crawlers, restorations, and overhauls for our customers. We have partnered with some of the best aftermarket and performance companies in the industry such as Vision X Lighting, Quick Fuel Technologies, Energy Suspension, Gator Wraps, PRP Seats and more. If you can dream it, Mike Franics and the guys at RSO performance can build it!
