Product Description
Genuine GM 12596509 Lash Cap
Fits 2014-Newer Gen V LT High Pressure Fuel Pump Applications | .060" Thick | Commonly Used with +30% to 38% Fuel Pump Lobes
The GM 12596509 lash cap is commonly used on 2014-newer Gen V LT-based V8 engines when installing a camshaft with an upgraded high pressure fuel pump lobe. This genuine GM lash cap measures .060" thick and fits the high pressure fuel pump setup on compatible 5.3L, 6.2L, and 6.6L LT engines, including LT1, LT4, LT2, L83, L84, L86, L87, L8T, and L8B applications. It is commonly used with camshafts featuring a +30% to 38% fuel pump lobe and also fits the intake valves on LS7, LS9, and LT4 engines.
Key Features & Benefits
- High Pressure Fuel Pump Lash Cap: Designed for compatible 2014-newer Gen V LT-based V8 high pressure fuel pump applications. This lash cap is commonly installed during camshaft upgrades that use an increased fuel pump lobe.
- .060" Thick Genuine GM Component: Measures .060" thick and provides the correct lash cap component for compatible LT high pressure fuel pump setups. Using the correct thickness is important when matching fuel pump lobe requirements during engine assembly.
- Common with +30% to 38% Fuel Pump Lobes: Frequently used when installing a camshaft with a +30% to 38% high pressure fuel pump lobe. This makes it a common supporting part during Gen V LT camshaft swaps and fuel system upgrades.
- Fits Popular Gen V LT Engines: Compatible with many 5.3L, 6.2L, and 6.6L LT-based V8 engines, including LT1, LT4, LT2, L83, L84, L86, L87, L8T, and L8B applications.
- Additional Intake Valve Compatibility: Also fits intake valve applications on LS7, LS9, and LT4 engines, making it useful for select GM performance engine service and valvetrain repair applications.
