Reinforced Delrin bumper to replace the C3 bumper on your FX Impact. The OEM C3 Bumper on all Impacts without the Power Plenum is rubber, which can be easily damaged at high power settings. This delrin puck design has been tested for roughly 5 years now without failure, no matter the beating it takes!
NOT Compatible with FX Impact MKII with Power Plenum !! The Power Plenum has a Delrin Bumper pre-built into the hammer.
Note: Replacing the C3 bumper with a Delrin Bumper will slightly decrease your ability to adjust your hammer spring adjuster/knob to lower power settings.
