When shopping for first-generation Porsche Cayenne suspension parts, you will often see the model codes 955, 957, and 9PA. These terms identify related Cayenne applications, but they are not enough on their own to confirm that a particular part fits your vehicle.

HPR lists a 2.5-inch nitrogen shock package for Cayenne 955/957 (9PA) models. Its front upper control arms are presented on separate product pages for the Cayenne 955 and 957. Before ordering, confirm your vehicle’s model year, VIN, original suspension type, and intended lift height with the supplier. Market-specific model years and suspension configurations can differ.

If you are planning a lift of around 2 inches, check three things. First, confirm that the shock absorbers are designed for your vehicle and target ride height. Second, determine whether the front alignment can be adjusted to suitable specifications after the lift. Third, inspect for adequate clearance through the suspension’s full range of motion, including at the tires, brake hoses, wiring, and other components.

HPR describes its adjustable upper control arms as a solution for lifted Cayenne 955/957 applications, including lifts of 1.5 inches or more. Adjustable arms can provide additional alignment range, but they do not replace a four-wheel alignment. The final settings should be measured on the vehicle after installation.
