Overview

The Ultra Racing 4-Point Rear Lower Bar is a chassis reinforcement component designed for the Nissan Elgrand (E52) 3.5 V6 2WD models from 2010 onwards. This bar aims to reduce chassis flex and body twist that can occur during aggressive driving maneuvers such as fast cornering, hard braking, or acceleration. By stiffening the chassis, it helps maintain tire grip and improve handling characteristics like understeer and oversteer.
Show original supplier description
The Ultra Racing 4-Point Rear Lower Bar is engineered to enhance the structural integrity of the Nissan Elgrand's chassis, specifically for the E52 generation equipped with a 3.5L V6 engine and 2WD, produced from 2010 and later. The vehicle's chassis is subjected to significant stress due to weight transfer during dynamic driving conditions, including cornering, braking, and acceleration. This stress can lead to chassis flex, body deformity, and twisting, which negatively impacts tire grip and can result in undesirable handling traits such as understeer and oversteer. This rear lower bar acts as a reinforcement, connecting key points of the chassis to resist these flexes and twists. By improving the rigidity of the rear chassis, the Ultra Racing bar helps ensure that the vehicle's suspension and tires can perform optimally, leading to more predictable and stable handling. The product is designed as a direct bolt-on component, requiring no modifications for installation, making it a straightforward upgrade for enthusiasts looking to improve their vehicle's performance and handling dynamics.
