Built by the original equipment turbocharger manufacturer, this Garrett GT3788VA Turbocharger fits 2004.5-2010 GM 6.6L Duramax LLY LBZ LMM. A turbocharger uses exhaust energy to compress intake air, which is what lets a diesel burn more fuel and make more power and torque without more displacement.

  • Center housing reinforced with three cobalt pins to reduce distortion and improve vane actuation
  • 2004.5-2005 LLY trucks also require Garrett vane position sensor adapter 771864-0001, sold separately
