Overview

The Ultra Racing URTW-RL2-3988 is a rear lower arm bar designed to connect to the lower arm mounts of a car's chassis. This brace reduces chassis flex and distortion under load, particularly during hard cornering, by connecting at two points. It helps improve chassis rigidity and reduces alignment flexing.
Show original supplier description
The Ultra Racing URTW-RL2-3988 Lower Arm Bar is a chassis component engineered to enhance vehicle handling and stability. This simple structure connects to the lower arm mount points of the chassis, specifically at two locations, to reduce flex and distortion. By minimizing the movement of the vehicle's lower suspension system during load, especially in hard cornering, it contributes to a more stable and responsive driving experience. This ensures a straightforward installation process. Ultra Racing emphasizes the use of steel over aluminum, explaining that achieving equivalent strength with aluminum would necessitate greater thickness, negating potential weight savings, while exotic alloys are prohibitively expensive for mass production. This rear lower arm bar is intended to improve the chassis's rigidity and reduce alignment flexing. The product's features include superior performance in handling and stability, improved dynamic safety, and an enhanced driving experience, making it suitable for various motorsport classes like Drifting, Time Attack, and Circuit Racing. The product comes with a Lifetime Warranty, reflecting the manufacturer's confidence in its durability and effectiveness.
