Description:
This Genuine GM Turbocharger (12643196) is an OEM IHI RHF4-VVM1 unit fitted to the 2.5 L Duramax (XLD25) diesel engine used in Holden Colorado, Chevrolet Colorado, and select Trailblazer models.
These are take-off units removed from brand-new GM/Isuzu engines prior to vehicle installation. They have never been used in operation and remain in excellent, near-new condition.

Perfect for restoring factory-correct boost performance and efficiency on your 2.5 L Duramax diesel engine at a fraction of the new OEM price.

Why Choose Genuine GM:
Genuine GM parts are built to precise factory standards, ensuring perfect fitment, proper boost control, and long-term reliability. Avoid low-quality aftermarket turbos that can lead to boost lag, oil leaks, or early failure.
