Grizzly Remanufactured Turbocharger 04.5-05 GM 6.6L Duramax LLY
Description
Bring your Duramax back to dependable performance with the Grizzly remanufactured stock replacement turbocharger. A worn or failing turbo can lead to reduced boost, sluggish acceleration, excessive exhaust smoke, and a noticeable loss of power under load. This remanufactured Garrett GT3788LVA provides an OE-style replacement for restoring the factory turbocharging system without stepping into an oversized performance turbo. It's a solid option for trucks that need reliable boost response for everyday driving and towing.
Built around the Garrett GT3788LVA platform, this remanufactured turbocharger is designed to restore the airflow and boost characteristics expected from the factory LLY Duramax setup. The variable-geometry design uses electronically controlled turbine vanes to adjust exhaust flow and help balance low-RPM response with airflow at higher engine speeds. Its stock-replacement configuration maintains the original style of turbo operation while providing a cost-effective alternative to purchasing a new turbocharger.

About WrenchConnected
WrenchConnected is an independent installation marketplace operating in partnership with Diesel Power Products.
How it works
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
Pricing
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
Your privacy
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.
