Invacare TDX4 Parts

This page lists replacement parts for the Invacare TDX4 power chair. We carry battery packs, chargers, tires and tubes, drive and caster wheel assemblies, SPJ+ joysticks and bus cables, motor brushes, armrests and hardware.

The TDX4 requires either two 12-volt Group 24 or two 12-volt 22NF batteries; we list 24 volt Group 24 (75 Ah) UB12750 and 22NF (55 Ah) UB12550 packs, and chargers are 24 volt 8.0 amp XLR models. Tires come in 14"x3" (3.00-8) and 12-1/2"x2-1/4" sizes, with pneumatic, foam-filled and solid options. The 6"x2" caster wheel assembly set (1122067) fits the TDX3, TDX4 and TDX5, and the right footrest hanger (1114766) also fits the Pronto M51, M71 and M94. The multiple actuator box (1136903) and 13" molded arm pad fit TDX and Storm series chairs. The model number and serial are on a label on the frame, usually under the seat.
