Specs At A Glance

Good To Know

Q: Do I need to replace both parts at once? A: Replacing the coil and CDI together is common when diagnosing a no-spark condition, since either part can fail and cause the same symptom. It also saves a second teardown if the other part is already weak.

Q: Will this fit my 4x4 FourTrax 300? A: This set is listed for both the 2x4 and 4x4 versions of the FourTrax 300 across the 1988 to 1993 range. Confirm your model code and year before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
