Invacare Pronto M94 with SureStep Parts

This page lists replacement parts for the Invacare Pronto M94 with SureStep power chair. We carry battery packs, chargers, tires, tubes, drive and caster wheels, SPJ+ and CMPJ+ joysticks, motor brushes, armrests and frame hardware.

The Pronto M94 requires two 12-volt 22NF batteries, such as the 24 volt 22NF (55 Ah) UB12550 pack, and uses 24 volt 8.0 amp XLR chargers or the 24 volt 5.0 amp on-board charger with square plug. Its drive tires are 14"x3" (3.00-8), and the complete drive wheel assemblies are for chairs manufactured after 10/18/01, so check the build date. The caster wheel assembly is 6"x2" (1122066). Some parts are shared with the AVIVA FX, Pronto M41, M51, M71 and M91, and TDX3, TDX4 and TDX5. The model number and serial are on a label on the frame, usually under the seat. Invacare serial numbers are on a label on the frame and follow formats like 02A12345 or 02BM123456. As an authorized Invacare dealer, we supply genuine OEM Invacare parts, with compatible alternatives on select items. Can't find your part?
