Ultra Racing 4-point rear lower chassis brace for Mercedes-Benz S-Class W221

The vehicle chassis is the part subjected to the greatest loads while driving. These loads occur mainly due to the transfer of the vehicle body’s mass during fast cornering, heavy braking or intense acceleration.

When cornering, weight transfer can cause one side of the vehicle to be subjected to up to three times more force than the other. This causes significant chassis twisting and body deformation, resulting in loss of tyre grip.

Chassis deformation and twisting while cornering can cause undesirable handling characteristics such as understeer and oversteer. The Ultra Racing brace helps increase the stiffness of the lower part of the chassis.

The product is intended for the Mercedes-Benz S-Class W221 with the S350 3.5 V6 engine and 2WD, model years 2005–2013.

• Design: rear lower chassis brace
• Number of mounting points: 4

Suitable for: Mercedes-Benz S-Class IV (W221).
