CAT 3406E "55" Injectors

Make some jam with a fresh set of 10R0955 injectors, better known in the diesel world as “55s.” These high-flow injectors are the go-to upgrade for serious power builders running modified CAT 3406E or C15 engines. Each set includes 6 injectors, sold together.

The 55s are the beginning of the "big dawg" injectors.  These injectors commonly come from marine or industrial Caterpillar applications. Injectors of this size can support an S500/GT55 (88MM, 91MM) etc and should be capable of supporting 1000HP

The 0R0955s deliver approximately 30% more fuel flow than standard “57s”, making them ideal for big horsepower builds, high-performance tuning, or drag/pull setups where fueling isn’t a bottleneck — it's the secret sauce. Whether you’re running a hot tune, big single turbo, or compound setup, these injectors bring the fuel to back it up.
