The factory dogbone mount on MK5/MK6 Volkswagens and 8J/8P Audis is engineered with a void that lets the transmission and engine move under load, softening shift feel and isolating the driver from the road. 034Motorsport's billet aluminum insert fills that void, cutting the associated slop for crisper shifts and a more connected, direct driving experience, without sacrificing ride quality or adding noticeable NVH. Unlike polyurethane insert options, this billet aluminum piece won't pack down and wear over time, so the improvement holds up over the life of the part. Important Compatibility Information This insert comes in two versions matched to the factory dogbone mount shape on your car, not simply by model year. The "2006-2008 (FSI)" option fits the early mount design; the "2008+ (TSI)" option fits the later mount design and includes 034Motorsport's Upper Dogbone Mount Insert, which is strongly recommended alongside any lower insert to prevent the puck assembly from rotating and bending the dogbone arm under aggressive drivetrain shocks.

Why does the later version include an upper insert too?034Motorsport strongly recommends pairing a lower insert with the upper insert to prevent the added forces of a lower insert from bending the dogbone mount arm during aggressive driving.
