Show original supplier description

The Ultra Racing Rear Lower Bar (UR-RLS4-443P) is engineered to enhance your vehicle's chassis rigidity. This component is designed for a direct bolt-on installation with no cutting or welding required, typically taking between 30-60 minutes with basic hand tools. This specific model, the UR-RLS4-443P, is a 4-point rear lower member brace. The product's specifications list a weight of 1.00kg and dimensions of 31.00cm x 4.00cm x 6.00cm. While listed under Proton branding on one page, this Ultra Racing brace is compatible with a wide range of vehicles. Notably, it is listed for the Proton Inspira, Mitsubishi Lancer GT/EX (2007-2017, 2WD), Mitsubishi Fortis 1.8 (2007-2017, 2WD), Mitsubishi Outlander 2.0 (2007-2013, 2WD), and Caliber SRT-4. It is crucial to verify fitment for your specific vehicle make, model, and year, as compatibility can vary.
