Case Saver Anti-Wear Plate Sonnax #100246-01, NP-240, NP136.
GM uses a wear plate to prevent the pump from wearing the magnesium case. However, the wear plate fails prematurely, allowing leaks to develop as the lugs wear through the case. Sonnax offers an improved version of the OE wear plate using harder materials.
- Fits NP136, 236, 246 and others with magnesium cases
- Harder than OE version
- Drop-in replacement
