Front SmartDiff: 8B 2.0

At a Glance

Losi engineers have designed a patent pending differential that knows exactly how to respond to track conditions and throttle input. Losi's innovative custom SmartDiff design adjusts the amount of lock based on throttle position for optimum power transfer into and out of corners. The results are improved maneuverability, increased off-power steering and outstanding acceleration.

The SmartDiff makes an easy, drop-in hop-up for every 8IGHT Buggy vehicle. The SmartDiff replaces the stock front diff on the 8IGHT without any additional modification required. Losi’s SmartDiff is fully assembled and ready for immediate installation.


  • Torque-sensing design - the SmartDiff adjusts automatically based on applied power
  • Lightweight spur gears and outdrives for greater acceleration
  • Fully assembled for a direct fit into stock diff locations
