D1 Chassis Information


D1 Chassis are torsion bar cars. Why torsion bars? Torsion bars provide consistency and stability. Our standard long-bar (LBX) front torsion bar design provides for the utmost weight transfer and forward bite on corner exit. With that, set ups and adjustments are consistent and predictable when you need a race car that you can rely on to be there every lap of every race!


D1 Chassis are Jacob’s Ladder cars. Our Jacob’s Ladder geometry is specific to provide that side bite every driver is looking for on corner exit. We guarantee the first lap you take in a D1, you will know exactly what we are talking about! Added bonus, every D1 Jacob’s Ladder is adjustable to fine tune your car with changing track surfaces.


Safety is very important to us and we want you to be sure that your driver is in the safest place possible out on the track. All of our D1 Chassis’ come standard with a left side ‘J-bar’ (aka ‘smith bar’) and right side ‘sissy bar’ for added driver protection when it is needed most.

  • The option of a full left side arm guard is available. This upgrade option provides a sleek look and for some added drivers comfort. In place of the ‘J-bar’, the option a ‘sissy bar’ behind the panel can be added.

We understand that some drivers do not care for these safety features such as a ‘J bar’ or ‘sissy bar’. Therefore, upon request we can construct a chassis with either of these features removed.

  • We also offer an roll cage halo upgrade for added extra protection.

  • An option of .083 wall chassis down tubes are also available upon request.


  • Race car drivers come in all different shapes and sizes. We want every one of our drivers to find their level of comfort their first time in the car. Our chassis has extra roll cage height to give our drivers to most cushion possible when it is needed.

  • Our chassis kits come standard with fiberglass 2 piece hood/nose and arm guards. The less sheet metal around the driver, the less radiant heat there is from vibration within the cockpit. That’s why our sleek body is not only designed for looks but also for comfort!

  • Our arm guard design creates the necessary elbow room for any size driver. The right side arm guard panel also allows for better air flow through the chassis to keep our drivers cool and comfortable.

NEW 2019 D1 Chassis


  • In 2016 we made chassis design changes to set us apart from our competitors. We had drivers new and existing looking for more feel from the car, so we went to the drawing board and produced the newest edition of the D1 Chassis with handling and strength in mind! These changes proved successful the first night the 2016 design hit the track! Forging into 2018 we have seen great success and positive feedback based on the direction we set out for in 2016. 2017 proved to provide even better results for our customers who combined for over 227 wins during the race season!


  • Every year we strive to improve our driver’s comfort level. In 2016 we added our Adjustable Pedal Rail System standard in every car. Our adjustable system grows with your driver, without compromising cockpit space. Our mounting rails are designed to be hidden under the floor board and allow for a sleek compact pedal system.
