Overview

The Ultra Racing URKR-LA4-3662 is a 4-point front lower brace designed to enhance chassis rigidity. It is constructed from steel plates ranging from 4mm to 5mm thick for the brackets, and hollow steel tubes from 1.2mm to 1.6mm thick.

This brace aims to reduce chassis flex caused by weight transfer during cornering, braking, and acceleration, thereby improving handling and stability. The design is intended to crumple during an impact for safety.

Show original supplier description

The Ultra Racing URKR-LA4-3662 is a 4-point front lower brace specifically designed for the Hummer H2 6.0 2WD models from 2003-2009. The chassis of a vehicle is subjected to significant stress from weight transfer during dynamic driving maneuvers, including cornering, braking, and acceleration. This can lead to chassis flex, vehicle body deformity, and twisting, which compromises tire grip and can result in handling issues such as understeer and oversteer. It is a bolt-on component, simplifying the installation process. The brace features a 4-point design, which provides robust support and enhances structural rigidity. The dimensions of the brace are 108cm x 37cm x 9cm, and it weighs 2.8kg. This specific brace is confirmed to fit Hummer H2 6.0 2WD vehicles from the 2003 to 2009 model years.
