Equilibrium Tuning proudly introduces our Front Subframe Locking Collar kit for VWAG 2015+ MQB 4cyl platforms!


Factory steel stamped and aluminum subframes have 4 attachment points. VW/Audi leave these points loose for ease of assembly, and alignment during factory assembly. Many customers have heard a clunk from the subframe shifting during operation of the car. This clunk is apparent especially during shifting from reverse to park. Volkswagen put out a TSB and a "fix" for this issue that was only a band aid.

The power steering rack is attached to the subframe. With the subframe floating around this will change the alignment of the car. Also anytime you need to drop the subframe to fix or change anything on the vehicle you WILL need to realign the car due to placing the subframe in a different spot after work is performed.


With the use of the subframe locking collars it fills the void in the factory subframe that usually is the cause of the shifting. While filling the voids we are also replacing the rear factory brackets with our upgraded reinforced brackets. This will add rigidity to the subframe and take any flex out during hard launches.
