Chassis Features
It takes a different kind of chassis to run fast and still be a consistent race car. You also want it to be user friendly so you can perform the changes or maintenance needed in those late rounds. That is why we build our Top Sportsman chassis with these things in mind. Check out the list of features below:

Race Tech Doorslammer Anatomy
The Chassis
Race Tech engineers each chassis to the highest standards, using domestic Aircraft Grade 4130 Chromoly tubing throughout. Each car is designed using in house CAD technology. This precision technology allows us to create a design that can be repeated, or design a custom chassis to your specifications and still retain a quick delivery time.
We use an in house customized design software program which tells us how long each tube needs to be, where to bend each tube, and how many of each tube we need,thus taking out all the guess work and retaining consistency. We also take extra care to index each bend so the writing is facing down so you don’t have to worry about the ink bleeding through your Powdercoating.
All of our tubing is bent on CNC bending equipment by highly trained in house veteran technicians. This allows us to maintain a uniform and repeatable bend, without stressing the tube.
We use special milling machines to notch each tube to exact tolerance, which maintains a better fit for a stronger weld area.
Each chassis is welded on Jig tables designed to hold each tube in the proper position.Each chassis isTIG welded using square wave technology by trained in house welders. (You don’t have to worry about somebody coming in from their day job to weld your chassis in their off time.) Each chassis is welded in the same consistent order designed by Race Tech to keep the chassis straight and true.
Every Race Tech race car is designed to handle your horsepower combination.
Finally each Race Tech chassis goes thru two quality control checks before they are powder coated or assembled. Each car is checked for incomplete welds, and quality of welds, while making sure it has all the options the customer has requested.
The Body
We are known for our great attention to detail, each body is finish fit and ready to go to paint. There are no large gaps or glasswork left to fill in, this can save you money when it’s time to paint. Each Dzus button is installed using brad rivets (not standard pop rivets), and we only use high quality preformed MR-10 scratch resistant polycarbonate windshields.
Design Qualities
When you purchase a Race Tech race car you get a car that is designed to function and perform with the highest reliability and consistency in the industry. We design our cars to be user friendly, making each part that requires service easy to access for repairs or service. Some of our design qualities which distinguish Race Tech cars include:
- We designed our Doorslammers from scratch to provide proper driveline angles for less drag and vibration.
- 4-Link brackets are designed to work together to provide proper instant center locations
- Transmission can be removed easily out the bottom due to our removable crossmember
- Master cylinder is mounted outside of driver compartment to keep fluid off your floor board.
- Seating position designed for visibility and comfort.
Trained Technicians
Your car is designed built and assembled by a well trained staff here at Race Tech. We train each technician on the proper techniques needed to build your race car. Our technicians are full time employees, not part time workers simply focused on making extra side money. This is why you can rest assured that your car is prepared properly and is ready to be pushed to the extremes required in today’s competitive world of drag racing.
