Not currently in production. Parts and reapairs are still available. The dirt late model was our first step into this line of chassis. We created this car using the same computer aided technology as was used in our asphalt line of cars. This car is built using 99% DOM Tubing and stress relieved using the Meta-Lax process. What ever setup you are used to, four bar, swing arm, Z-link, or clamped, you can do it without buying any extra parts. The design of our chassis allows you to simply move the same bars around for any configuration.
