Review on πŸ’ͺ Enhanced Performance: P7100 Injection Pump 3K/4K Governor Springs for Cummins '94-98 12V 5.9L - Perfect Compatibility! by Gerald Barrett

Revainrating 5 out of 5

Great price for a complete set.

complete set that works well. P7100 pumps respond very well to simple mods like governor springs and fuel plates. This ESC Spring Kit gives you the option to go from stock to a safe 3k, or go all out and go all the way to the 4k limit as you make more mods to support. this level of sales. When installing 4k limiter springs, 60/lb or higher valve springs should be used to avoid valve shifting and possible engine damage.
