Thumbnail Filmstrip of 5.9 | 3.9 Cummins Tappet SBI VL156 Images
The SBI Tappet VL156 is a foundational component for the legendary Dodge 5.9L Cummins and 3.9L 4BT diesel engines, serving as the critical link between the camshaft and the rest of the valvetrain. In the high-torque, heavy-duty world of diesel performance, the tappet (or valve lifter) must endure relentless mechanical pressure and friction. This SBI tappet is engineered to translate cam lobe movement into valve action with absolute precision. By utilizing the highest quality materials and rigorous quality control processes, SBI ensures that each unit restores the factory-spec timing and lift required for your engine to maintain its signature power and efficiency.
- Precision Dodge & Cummins Fitment: Specifically designed and manufactured to meet the exacting requirements of the Dodge 5.9L and 3.9L 4BT diesel platforms.
- Dual-Application Versatility: Engineered for use as either an intake or exhaust tappet, simplifying the parts-sourcing process for complete engine overhauls.
- OE-Spec Manufacturing: Produced using advanced metallurgical processes to ensure each lifter meets or exceeds original equipment structural standards.
- Enhanced Durability: Built to withstand the high-contact stress and thermal demands typical of high-mileage diesel workhorses and performance builds.
- Sold Individually: Offers professional engine builders and DIY enthusiasts the flexibility to replace a single lifter or purchase a full set for a comprehensive rebuild.
Choosing the VL156 is a smart investment in the long-term health of your engine’s camshaft. Because the tappet is a "wear item" that interfaces directly with the cam lobes, using a high-quality replacement is essential to prevent premature lobe wear or valvetrain noise. SBI’s commitment to stringent quality control means you can trust that each tappet provides the smooth, consistent operation necessary for optimal fuel injection timing and gas exchange. Whether you are refreshing a high-mileage 5.9L 12-valve or building a custom 4BT swap, these tappets provide the professional-grade reliability and precision fitment that Cummins owners have come to expect.
