BD Diesel 1043055 BOSS 6.2L Exhaust Manifold Kit for Ford F-150, F-250, and F-350
The BD Diesel 1043055 exhaust manifold kit replaces both the left and right side manifolds on Ford trucks equipped with the 6.2L BOSS V8 gas engine. The manifolds use 0.275 inch uniform wall thickness, 75 percent thicker than the factory castings, so they resist the warping and cracking that leads to exhaust leaks and snapped bolts on the stock parts. The kit installs as a direct replacement and includes the fasteners and gaskets needed to complete the job.
Key Features
- Thick Wall Construction: 0.275 inch walls resist warping and cracking under repeated heat cycles
- Complete Kit: Includes left and right manifolds with all fasteners and gaskets needed for installation
- Corrosion Resistance: Painted finish protects against surface rust and scaling
- Reinforced Fasteners: Longer bolts and added spacers reduce stress on the fastener joint and help prevent snapped manifold bolts
- Improved Flow: Outflows the factory manifolds by 10 percent for better exhaust evacuation
- Direct Fit: Bolts in place of the factory manifolds using the factory mounting points

Frequently Asked Questions
What is the 1043055?
It is a complete left and right side exhaust manifold kit built for Ford trucks with the 6.2L BOSS V8 gas engine.
Which engines does this kit fit?
It fits the Ford 6.2L BOSS V8 gas engine only. It does not fit the 6.7L Power Stroke diesel or other Ford V8 gas engines.
Does this kit include both manifolds?
Yes, it includes the left and right side manifolds. A separate driver side only kit is available if you only need to replace one side.
Are gaskets and fasteners included?
Yes, the kit includes the mounting fasteners, spacers, and gaskets needed to install both manifolds.
Why are these manifolds less likely to crack than the factory parts?
The walls measure 0.275 inch, about 75 percent thicker than the factory castings, which gives the manifold more material to absorb heat cycling without warping or cracking.
Will this kit improve exhaust flow?
Yes, the manifold design outflows the factory manifolds by 10 percent, which helps the engine expel exhaust gas more efficiently.
Do I need to replace the manifold bolts during installation?
The kit includes longer bolts and added spacers designed to reduce stress on the fastener joint. Use the included hardware rather than reusing the factory bolts.
What is the warranty on this kit?
BD Diesel backs this kit with a 36 month or 75,000 mile limited parts warranty.
Is this kit legal for use in California?
This kit is not for sale or use on emissions licensed California vehicles.
Installation Instructions
- Disconnect the negative battery cable and allow the engine to cool completely before starting work.
- Raise and support the vehicle safely, then remove the components needed to access the exhaust manifolds on both sides of the engine.
- Remove the factory manifold bolts and separate the factory manifolds from the cylinder heads.
- Clean the cylinder head mating surfaces to remove all gasket material and debris before installing the new parts.
- Position the new gaskets on the cylinder head mating surfaces.
- Install the BD Diesel manifolds using the included spacers and fasteners, following the factory service torque sequence and specification for your specific truck and engine.
- Reconnect the exhaust downpipe and any brackets, heat shields, or sensors removed during disassembly.
- Reinstall the components removed for access, then reconnect the battery.
- Start the engine and check for exhaust leaks at both manifold joints before returning the truck to service.
