Frequently Asked Questions

Can the QSK23 in the EX1200 be replaced with another brand?
Not recommended. The EX1200's hydraulic system and ECU are deeply integrated with the QSK23. Swapping brands requires extensive modifications and may void warranties. MSD supplies OEM and quality aftermarket QSK23 parts for optimal compatibility.
