Lower engine torque arm mount (dog bone style), VW Golf/Jetta IV 1999-05, New Beetle 1998-06. Price is for a set of 2 pieces. These bushing are installed in your car's lower engine torque arm and are a clever way to increase a vehicle's performance. Vehicle manufacturers often create motor mounts with voids or holes in them. These voids are designed to give the mount a level of play that can soften engine vibration. Our Motor Mount Inserts fill those voids, effectively making the mount solid. While this does decrease the vibration that can be absorbed by the mount, it also dramatically increases the throttle response. By allowing the engine less movement, these can increase throttle response, reduce wheel hop, and even improve traction.
