Product Description
Genuine GM 12660709 Fuel Rail for TBSS and NNBS LS Truck Intake Manifolds
Fits 2006–2009 Trailblazer SS and 2007–2013 LS Truck NNBS Intake Manifolds
Complete or restore a compatible LS intake-manifold assembly with genuine GM fuel rail part number 12660709. This application-specific fuel rail is designed for the intake manifolds used on 2006–2009 Chevrolet Trailblazer SS models and 2007–2013 LS-powered “NNBS” trucks. It is an ideal choice when replacing a missing or damaged rail or assembling one of these popular GM intake manifolds for another compatible LS engine project.
Because this is an original GM component, it provides the correct factory-style rail configuration for the supported TBSS and NNBS intake designs without requiring a universal aftermarket fuel-rail conversion. The exact GM 12660709 identification also makes it easier to confirm that the correct rail is being selected for the intended intake manifold. This listing includes the fuel rail only; the intake manifold and other fuel-system components are not included.
Key Features & Benefits
- Genuine GM Part Number 12660709: Manufactured as an original GM fuel-system component for the supported intake-manifold applications. Its exact GM part number provides a reliable reference when replacing a missing or damaged rail or sourcing the correct component for a compatible TBSS or NNBS intake assembly.
- 2006–2009 Trailblazer SS Intake Compatibility: Fits the intake-manifold design used on 2006–2009 Chevrolet Trailblazer SS applications. This makes the rail suitable for servicing an original TBSS intake or completing a compatible LS engine project built around the popular Trailblazer SS intake-manifold configuration.
- 2007–2013 NNBS LS Truck Intake Compatibility: Also fits the LS truck intake manifolds used on 2007–2013 “NNBS” applications. The defined intake and model-year range helps distinguish GM 12660709 from fuel rails designed for earlier LS truck manifolds or unrelated GM intake configurations.
- Factory-Style Intake-Manifold Solution: Designed specifically around the supported GM intake configurations rather than as a universal aftermarket fuel rail. This makes it a straightforward choice for builders who need the corresponding factory-style rail for a compatible TBSS or late-model NNBS LS truck intake manifold.
- Fuel Rail Only: This listing includes genuine GM fuel rail 12660709 only. The NNBS intake manifold, injectors and other fuel-system components are not included; customers needing the corresponding NNBS intake manifold should reference GM part number 12638038 as a separate product.
Notes
- Fuel rail only; the intake manifold and other fuel-system components are not included.
- See GM part number 12638038 for the corresponding NNBS intake manifold.

OEM rails at a great price compared to the big parts houses that only show the price and don't even offer the product. Michigan Motorsports always has come through for me and they save me a lot of money. Thanks guys and girls
