A fuel injector has a fuel inlet, a fuel outlet, and a fuel passageway extending along an axis between the fuel inlet and the fuel outlet. The fuel injector comprises a body, an armature, a spring, and a spring stop. The body has an inlet portion, an outlet portion, and a passage disposed between the inlet portion and the outlet portion. The armature is disposed within the passage and is displaceable along the axis relative to the body. The spring is disposed within the passage and applies a biasing force to the armature. The spring has a first end disposed proximate the armature and a second end opposite from the first end. The spring stop is disposed within the passage and has a first and second portion. The first portion includes at least one projection engaging the passage. The at least one projection extends obliquely with respect to the axis and in a direction general toward the inlet portion.
