Supercharger Belt Wrap Kit for Mercedes-AMG M113K (2003–2008)

Maintain consistent boost and protect your supercharger drive system with this Ultimate Performance Belt Wrap Kit, engineered specifically for Mercedes-AMG vehicles equipped with the M113K supercharged V8. Designed to eliminate belt slip under high boost conditions, this kit ensures reliable power delivery across the entire RPM range.

Factory M113K setups are known to suffer from belt slip and weak double-idler assemblies when subjected to increased boost or aggressive driving. This belt wrap kit corrects those shortcomings by increasing belt contact on both the crank and supercharger pulleys while reinforcing the factory idler system for long-term durability.
