Supercharger couplers (also known as isolators) link the drive shaft to the gearset inside the snout of the unit. Over time, the factory part can wear or loosen, leading to rattle at idle, noise on lift-off, or excessive free play.
Replacing a worn coupler restores quiet running and protects the supercharger from further damage. At Powerhouse, we supply both OEM sprung couplers and solid replacements, depending on your platform and needs.
Our range of supercharger couplers covers popular Eaton units including M112, M122, and TVS series superchargers, fitted to vehicles such as Jaguar, Range Rover, Mercedes, Audi, Mini, Aston Martin and other performance models. Each part is built to exacting standards for long service life.
If you’re unsure of your supercharger condition / health then don’t miss out on our Supercharger Rebuild Services.
