Newbie
AMG engineers are not idiots' the have an reason why the build the pulley like 2 Pulleys with an rubber damper in between to keep the force away from the crank and keep the SC Gearbox ......
and 2 Belts strait on 1 damper will make an strange Frequency on the crank.....

Here is some more data on our new pulley:
- Stock pulley is TUFF bonded by vulcanized rubber.. that's it.
- In comparison, some of the aftermarket pullies are pinned at different points around the circumference.
- Our pulley has 2 carbon steel pins that are preseed into the solid mounting section which are harder than the alloy pulley itself. The rest of the mounting is done by stainless steel hex bolts.. From what I was told, the pulley would disintegrate before the mounting hardware would.
- Torsional energy is absorbed via the accessories pulley and counter weight which is mounted on rubber

Glad to see you got rid of those ****ty button head bolts!!!!!! had a friend of mine with them on a set of adjustible cam gears that loosened up and timing advanced, and well lets just say the inspection hole in his block was not pretty! you can certinally put more torque on a standard allen than a buttonhead!!
