The DragRace Concepts Slash Drag Pak ARB Anti Roll Bar Kit is a rear suspension option developed specifically for drag racing applications. Designed to work with the Custom Works Adjustable Rear A-Arms (CSW3242 - sold separately), the ARB design ties the rear suspension together allowing the rear arms to work as a single unit rather than independently. This helps increase traction and stability under power compared to an independent suspension set up. Additionally, the rear shock tower alters the shock geometry, placing the shocks in a more vertical position to improve rear weight transfer at launch.
