2801-301 is a critical component for V6 driveline setups, specifically designed as a Pinion Tri-Flange with a 12/18 bolt hole configuration. When diagnosing driveline vibrations, a worn or misaligned companion flange can often be the culprit. If you notice a vibration that correlates with vehicle speed but disappears in neutral, the flange face may be out of alignment, leading to excessive runout and vibration issues.
This flange features a spline count of 30 and a spline diameter of 1.250 inches, ensuring a robust connection with the driveshaft. The hub diameter measures 1.848 inches, which is essential for proper fitment in your application. Additionally, the through hole measures 1.000 inches, allowing for effective mounting and alignment.
When installing the 2801-301, ensure that the mating surfaces are clean and that you torque the bolts in a star pattern to avoid any misalignment. After installation, checking the face runout is crucial to prevent future vibration issues. Here are some key points to consider:
- Bolt Circle Diameter: 100mm
- Hub Diameter: 1.848 inches
- 30 Splines for secure connection
- Through Hole: 1.000 inches
- Designed for V6 applications
Using the 2801-301 will restore proper function and eliminate driveline vibrations, ensuring a smooth and reliable driving experience.
