Crashing over potholes has stopped
Replacement for my 2024 A4 B9 2.5 TFSI. Top mounts and bearings went on at the same time while it was apart. The paint and plating look like they will survive a few winters of salt. Result is the car no longer floats over crests and settles in one movement.

Car feels new again
Replacement for my 2015 Q3 8U 2.0 TDI. Damping is progressive when you compress it by hand, not dead at the top of the stroke. I torqued everything at ride height rather than with the suspension hanging. Result is the clonk over speed bumps that started this job has completely gone.

Good dampers, buy the top mounts too
Bought for a 2011 Q3 8U. The garage did the pair and the alignment came back within spec straight away. Damping is progressive when you compress it by hand, not dead at the top of the stroke. On balance body roll through roundabouts is properly controlled again. Fine for the money, with that one caveat.

Well damped, not harsh
Cross-referenced the OE number against my 2003 A3 8P before ordering. I torqued everything at ride height rather than with the suspension hanging. The rod is properly finished with no machining marks and the seal is clean. Result is the clonk over speed bumps that started this job has completely gone. Happy to recommend it.
