4-Point Rear Lower Bar

The Ultra Racing 4-Point Rear Lower Bar (URTH-RL4-3150) is engineered to enhance the chassis performance of specific vehicles by reducing flex and deformity. During dynamic driving maneuvers such as rapid cornering, hard braking, or aggressive acceleration, the vehicle's chassis experiences significant weight transfer. This can cause uneven force distribution across the vehicle body, leading to flex, twisting, and a loss of tire grip. The Ultra Racing bar aims to counteract these effects, mitigating issues like understeer and oversteer for improved handling stability. Constructed from robust materials, this rear lower bar features brackets made from 4mm to 5mm thick steel plates. The structural tubing utilizes hollow steel and oval tubes with thicknesses ranging from 1.2mm to 1.6mm. This combination of materials provides the necessary rigidity and strength to maintain consistent geometry under stress. This specific Ultra Racing bar is designed for direct fitment on the Isuzu MU-X (RF10) with the 2.5L engine and 2WD drivetrain, model years 2013-2021. Installation is straightforward, requiring no modifications to the existing chassis. The product is a bolt-on component that directly attaches to the rear lower section of the vehicle's frame. Ultra Racing's commitment to performance is demonstrated through its motorsport division, which uses track and competition feedback to refine its products.
