Product Description
The Porsche 911 Carrera 997 Front Shock Absorber, OEM Reference 99734304522, is a suspension component designed to help maintain vehicle stability, controlled body movement, and consistent tire contact with the road. Compatible applications include selected rear-wheel-drive Porsche 911 (997) models, including certain Carrera, Carrera S, and Carrera GTS versions, subject to the vehicle’s suspension configuration.PORSCHE 911 CARRERA 997 GTS FRONT SHOCK ABSORBER
This reference is associated with front-axle shock absorbers from Bilstein’s replacement range. Depending on the exact variant, the unit may feature gas-pressure damping, a suspension-strut design, and compatibility with Porsche’s Porsche Active Suspension Management (PASM) electronic damping system.
A properly matched shock absorber helps control suspension movement during braking, cornering, and uneven-road driving. Replacing worn dampers can help restore predictable handling and ride control.
Before ordering, verify the complete part number against the vehicle identification number (VIN), as compatibility can vary by model year, drivetrain, and suspension equipment.

Recommended Replacement Considerations
Shock absorbers should be inspected if the vehicle shows excessive bouncing, reduced stability, uneven tire wear, fluid leakage, or unusual suspension noise. These symptoms can have other causes, so a professional inspection is recommended before replacing parts.
For balanced handling, shock absorbers are generally replaced in pairs on the same axle. Installation should be performed by a qualified technician, with the relevant mounting hardware and suspension components inspected at the same time.
