The +4mm longer chassis will be smoother and less twitchy on entry, carry more mid-corner speed, and have more on power steering, but still have enough grip for clay surfaces.
A Prototype of the +4mm chassis was used by Dakotah Phend to win the 2022 ROAR Dirt Nationals, along with several other races during the 2022 and 2023 race seasons. The +4mm chassis is the race teams' choice for dirt and clay tracks.
The chassis is CNC machine from 2.0mm 7075-T6 aluminum, milled for weight reduction and optimized flex characteristics, then hard anodized for wear resistance and protection.
No other parts or modifications are required for this +4mm chassis to fit the 22 5.0 DC ELITE or 22 5.0 DC Roller.
