Thumbnail Filmstrip of 6.7 Cummins Head Saver Shim SBI 230-2176 Images
The SBI Head Saver Shim 230-2176 is a precision-engineered "rescue" component designed to breathe new life into Dodge Ram 6.7L Diesel components that would otherwise be destined for the scrap heap. In the world of high-performance diesel machining, removing material from the cylinder head or engine block deck is often necessary to ensure a perfectly flat sealing surface. However, excessive machining can lead to "compression ratio creep," where the combustion chamber volume becomes too small, potentially causing engine knock or catastrophic contact between the valves and pistons. This shim acts as a precision spacer, effectively adding back the material lost during the resurfacing process to restore the engine's internal dimensions to their intended factory state.
- Restores Critical Geometry: Re-establishes the correct deck height to maintain OEM compression ratios, proper valve-to-piston clearance, and accurate cam timing.
- CNC Laser Precision: Each shim is precision-cut using advanced CNC laser technology, which eliminates the "rolled edges" or burrs typical of cheaper, press-punched alternatives for a perfectly flat fit.
- Premium Material: Manufactured from 0.020-inch cold rolled steel, providing the durability and heat resistance required to survive the intense pressures of a 6.7L Cummins combustion chamber.
- Performance Correction: Actively eliminates technical issues caused by over-machining, such as timing chain flutter and improper valvetrain alignment.
- Cost-Effective Salvage: Engineered specifically to save expensive, machinable cylinder heads that have been surfaced below factory limits, preventing the high cost of a total head replacement.
Choosing the 230-2176 is an educational and strategic move for any serious engine builder. By utilizing a Head Saver Shim, you aren't just "fixing" a part; you are restoring the delicate synchronization of the entire engine. When the head is milled too thin, the distance between the crankshaft and the camshaft changes, which can retard or advance your timing and lead to poor fuel economy or power loss. This 0.020-inch shim provides the exact thickness needed to push those components back into their original spatial relationship. Whether you’re finishing a high-mileage rebuild or a performance head job on a 6.7L Ram, these shims provide a reliable, factory-spec solution that ensures your engine remains as efficient and durable as the day it was built.
Note: SBI Head Saver Shims should be installed on the block surface with the Cylinder Head Gasket on top and should be used with Conventional Head Gaskets Only.
