Critical Installation Note
One-Time Use Hardware: Bentley and Porsche engineering standards specify that many of the bolts connecting the control arms to the
971407246Lknuckle are Torque-to-Yield (Stretch Bolts). These must be replaced with new hardware whenever the suspension is disassembled to ensure the safety and integrity of the aluminum threads.
Fitment Verification
Because the 971 platform has various revisions for Steel Suspension vs. Air Suspension and Ceramic Brakes vs. Iron Brakes, the suffix of the part number is vital.
