The front upper control arm connects the vehicle’s chassis to the steering knuckle and helps define suspension geometry. When a Porsche Cayenne 955 and 957 is lifted, the arm’s operating angle changes. Depending on the setup, that can make it harder to achieve suitable alignment within the original adjustment range.
HPR provides separate product pages for Porsche Cayenne 955 and 957 front upper control arms. The listings describe a left-and-right kit that includes new ball joints, installed OE-style rubber frame bushings, and washers. HPR also lists the arms for lift applications of 1.5 inches or more. Confirm the exact fitment for your vehicle before ordering; model year and suspension configuration matter.
Use suitable tools during installation to avoid damaging ball-joint dust boots and bushings. Follow the vehicle’s service procedures for fasteners and tightening. Once the vehicle is back at its normal ride height, have the alignment measured and adjusted by a qualified shop.
After installation, check the ball-joint boots, bushings, alignment, and fasteners during routine maintenance. Proper fitment and follow-up checks are important parts of a suspension upgrade.
