TX-7 Friction Reducing Treatments
The TX-7 line is a synthetic blend friction reducing treatment formulated to work with the fluid already in your vehicle, not to replace it. One bottle per system: engine, manual or automatic transmission, differential, power steering. 2A Gun Oil is the same friction chemistry built for firearms.
