ALPS 2.1K Potentiometer 8x OEM trim pot resistor was made by ALPS. It fits ALPS analog joysticks. This trimmer potentiometer works with PS5 DualSense and some PlayStation 4 DualShock 4 wireless controllers with 2.1K ohm ALPS thumbstick module inside 1. Solve most of joystick problems: 80% chances of joystick problems were caused by the potentiometer. In another words, the rotary mechanism and the tactile switches are not the problem. You can simply replace the side potentiometer sensor alone to solve most of the problems 2. Additional resistors included: Complicated moving mechanism and daily wear and tear can cause drifting, and even new potentiometers can not be 100% balanced. Calibrating in controller settings might not work. Please solder one or more paralleled resistors at the opposite direction against drifting Compatibility Notes: 1.ALPS version is not interchangeable with the orange version made by Favor Union 2.ALPS potentiometers come in two different resistance values. Never judge its value by its color. Make sure the resistance value is 2.1K ohm before ordering 3.Please choose 10K ohm for most PS3, PS4 DualShock 4, Xbox One, Elite Series 1 and 2, Xbox Series S|X and Switch Pro controllers
