Front One-Way Assembly: JRX-S

JRX-S racers looking for a more aggressive setup, or who run on high-grip surfaces will want to check out the new Front One-Way Differential from Team Losi®.

At a Glance

The LOSA3350 Front One-Way Assembly is a drop in unit that replaces the stock front differential. The assembly includes a precision machined and lightened aluminum housing with one-way bearings in either side, outdrives, shafts, one-way pulleys and all hardware. This type of one-way is a popular tuning item with racers who like and aggressive set up and/or run in extremely high bite conditions. Typically a front one-way will yield better acceleration out of a turn but does not have any braking capacity and is less forgiving. The front one-way can also be helpful in carrying greater corner speed on high-speed tracks with sweeping turns. All parts for the JRX-S front one-way are available separately.


  • Lightened aluminum housing
  • One-way bearings on either side
  • All necessary hardware included
