Did you originally install a set of 3,000 RPM governor springs into your P7100 injection pump and thought it would be enough, but now realize you would rather have the ability to fuel up through 4,000 RPM's?
No worries, we have you covered with this Bosch 4K spring for your 1994-1998 Dodge 5.9L 12 Valve Cummins.
NOTE: SOLD SINGULARLY. REMEMBER TO ADD TWO TO YOUR CART.
