About Us
JERK Engineering is a company centered around motion; call it the Nomadic Lifestyle, the Adventure Life, or living the Overland Experience. At jerk Engineering, we constantly have your lifestyle in mind.
Form, Fit, and Functionality drive our designs, drive our solutions to the challenges faced while you live the adventure life. Safety is a primary pursuit in every design, in every product, and remains a continuous pursuit for our company, as we want you to live out loud, safely, in all of the areas of our amazing and beautiful country, and world that you choose to adventure to!
Why are we jerk engineered products? Well, we dream up, design, prototype, and move into production, and sell products that assist you in your pursuit to adventure, to be out in motion, free to move and to be wherever you wish… We are a company of motion. jerk is the physics term defining the rate of change of acceleration, just as acceleration [a] is the rate of change of velocity [v], (speed), jerk is is the rate of change of acceleration, it’s the third derivative of displacement [r], (distance)… Think of when you are in a powerful vehicle or roller coaster that launches at the start, and it starts to accelerate quickly, it jerks your head back and presses your body into the seat, you have, at that moment, felt the thrill of ‘jerk’!
We provide innovation in design to bring products to market that support the adventurer’s desire to wander. We passionately work with the principles of safety, quality, and product reliability at the core of every action and decision within the walls of Stoltek Engineering and JERK Engineered Products.

Installations
The XR is the well-known X Rack. With complete tig welded aluminum the XR can accommodate your original equipment spare wheel, or mounting of up to a 33" wheel & tire.If you have a big lift and you went bigger it will accommodate nearly any size after-market tire & wheel setup you went for - call us and our Engineering department will make sure we can accommodate your size.
We have applied engineering design to the geometry and strength calculations, and with an innovative design (patent pending) have created a system that does NOT piggy-back directly off of the hinges of the van, therefore there is no need to force the use of only 180-degree hinges to mount your rear systems to your van any longer.
The XR as with all of the JERK Engineered Products line of rear mounted systems, is engineered to serve you on the toughest terrain and harshest places you may travel to.
The XR tire carrier mounts securely to the innovative structural hinge brackets and requires a small mounting hole in the door and slightly larger one hidden behind the interior trim panel. Included are both exterior and interior reinforcement plates to ensure your system is integrated with your van properly.
Be assured, the installation of this unit is simple for all to do. Note again that there is no need to change out hinges, ever, you keep your original hinges, which are painted the color of your van!
