Quantum J4 Parts

This page lists replacement parts for the Quantum J4 power chair. We carry the 24 volt battery pack and chargers, the Q-Logic NE+ joystick controller and inline joystick mount, seat cushions and cushion covers, seat back cushions, a hi-back seat assembly, footplates, saddle bags, seat belts, and an oxygen tank holder.

The J4 uses a 24 volt 22NF battery pack. Chargers listed are 24 volt 8 amp XLR models, including the HP0240WB compact charger. The joystick is the Q-Logic NE+ Series 6-key controller (CTLDC1560), and the inline joystick mount (FRMASMB12744) is shared with the Jazzy 600. Seat cushions come from the Stealth Glacial SP, Stealth Solution, Stealth ZEN SP, and Tru-Comfort 2 lines in several sizes, so measure your seat before ordering. The model number is on the frame label, usually under the seat. Can't find your part? Contact us with your model number and a photo of the old part, and our team will help track it down.
