FAQs
What vehicles is the Ci Ignition XR307 Rotor Arm compatible with?
It is compatible with Jeep Cherokee (XJ) 4.0 i models from 12/1991 to 09/2001, and specifically with OEM references CHRYSLER 56027019 and JEEP 56027109.
What does 'no interference suppression' mean?
This means the rotor arm is designed to minimize or eliminate electrical interference that could disrupt radio signals or other electronic components in the vehicle.
How do I know if I need to replace my rotor arm?
Symptoms include engine misfires, rough idling, hesitation, poor acceleration, or a general decrease in engine performance. Visual inspection may reveal cracks, burns, or carbon buildup.
Can I install this part myself?
While installation is straightforward for experienced DIY mechanics, it involves working within the ignition system. If you are not comfortable, it is recommended to have a qualified technician perform the installation.
What are the dimensions of the XR307 rotor arm?
The rotor arm has a length of 75 mm and a height of 75 mm.
What is the difference between this rotor arm and others?
The primary differences lie in specific vehicle fitment and design features like interference suppression. Always ensure the part number and compatibility match your vehicle's requirements.
Troubleshooting
Engine misfires or runs rough
Ensure the rotor arm is correctly seated and securely fastened. Check for any cracks or carbon tracking on the rotor and distributor cap. Verify compatibility with your vehicle.
No spark or weak spark
Inspect the rotor arm for damage. Ensure the connections to the ignition coil and distributor are clean and secure. Test the ignition coil and other related components.
Difficulty installing rotor arm
Double-check that you have the correct part number for your vehicle. Ensure the distributor shaft is clean and free of obstructions. Do not force the rotor arm; it should fit snugly.

Setup, Compatibility & Care
Compatibility Verification: Before installation, confirm that your vehicle's OEM part numbers match `CHRYSLER 56027019` or `JEEP 56027109`, or that your vehicle is a Jeep Cherokee (XJ) 4.0 i from the specified model years (12/1991 to 09/2001). Cross-reference with part numbers like `BLUE PRINT ADA101407` or `LUCAS CAV DRB910C` if applicable.
Installation: Installation should be performed by a qualified technician. Typically, this involves removing the distributor cap, carefully removing the old rotor arm (often secured by a screw), installing the new XR307 rotor arm, and then reassembling the distributor cap.
Care: This is a non-serviceable component. Regular inspection of the distributor cap and rotor during routine maintenance is recommended. Look for signs of wear, carbon tracking, or physical damage. Cleaning is generally not required or recommended; replacement is the standard procedure if issues arise.
