STG 996 / 997 Rear Dogbone Spherical Bearing Kit

STG Porsche 996 / 997 Rear Dogbone Spherical Bearing Kit

Precision drivetrain control for road & track

Upgrade the rear drivetrain stability of your Porsche 996 or 997 with the STG Rear Dogbone Spherical Bearing Kit — engineered to eliminate compliance in the factory rubber mount and deliver sharper throttle response, improved traction, and more consistent handling under load.

Designed for enthusiasts who demand precision, this kit replaces the OEM rubber bushing with a high-quality spherical bearing, significantly reducing unwanted drivetrain movement without compromising durability.

Why Upgrade the Rear Dogbone Mount?

The factory rear dogbone mount allows excessive drivetrain flex, particularly during:

• Hard acceleration

• Aggressive gear changes

• Track driving or fast road use

Over time, this compliance leads to:

• Sloppy throttle response

• Inconsistent rear-end behaviour

• Accelerated wear in surrounding mounts

The STG solution directly addresses these issues by positively locating the drivetrain, ensuring power is transferred to the road with minimal loss.
