Product Description

The Granatelli 540244 is a 44mm water-cooled external wastegate built for custom turbocharged applications that need stable, repeatable boost control. Its traditional diaphragm design and mechanical spring-based operation help regulate exhaust bypass flow, reducing the chance of uncontrolled boost spikes in street or race setups.

This part is not vehicle-specific and should be listed as a universal turbo system component. Proper installation requires a compatible 44mm wastegate flange, matching exhaust manifold or up-pipe configuration, suitable dump routing, and coolant line integration for the water-cooled housing. It is best suited for fabricators, tuners, and builders assembling custom forced-induction systems rather than stock replacement applications.

No lift or drop height applies to this product because it is a turbocharger control component and does not affect suspension height.
