POWERKIT.50 V2: Extreme Power Increase to 20–30 J for Umarex T4E HDP/TP 50 (GEN1 & GEN2)

This tuning kit is the ultimate solution for owners of Umarex T4E HDP / TP 50 7.5J pistols (both GEN1 and GEN2 versions) who demand the highest possible performance. Precision-engineered in Germany from high-strength aluminum and stainless steel, this upgrade pushes your weapon's limits up to 30 Joules.

The kit's design includes a pressure chamber insert and a specially shortened valve pin, allowing a larger volume of CO2 gas to be released with each shot, dramatically increasing the kinetic energy of the projectile.

Purpose, Technical Details, and Compatibility

Intended Use: The kit is designed to increase power for self-defense or training. Since CO2 is highly temperature-dependent, we recommend storing capsules at room temperature for optimal gas expansion and maximum pressure.

  • Compatible T4E Weapons: HDP 50, TP 50 (7.5 J versions, GEN1 & GEN2).
  • Performance: Increase by over 20 Joules (Total 20–30 J).
  • Material: High-strength special aluminum and stainless steel pin (for better sliding).
  • Package Content: 1x pressure chamber insert, 1x valve pin (shortened by 2 mm).

Frequently Asked Questions about Functionality and Installation

Question: Is the kit compatible with the GEN2 version?
Answer: Yes, this Powerkit.50 V2 is designed to be fully compatible with both the GEN1 and the new GEN2 7.5J models.
Question: Do I need to change other valves during installation?
Answer: No, the installation is designed so that no additional valve is needed in the pressure chamber. Simply press the insert in using the included screw and remove the original throttle valve.

Notice: Modifying the weapon voids the warranty and certification. Homedefence-24, UMAREX GmbH & Co. KG, and RPR SHOP assume no liability for consequences resulting from modifications!
