Isolated Drive System Sprocket Kit

Part Number 40287-07


Finish / Color: Black



Introduced on the '08 Touring models, the Isolated Drive System improves rider comfort and ride quality by dampening the mechanical noise and vibration caused by the engine's torque pulses. The rubber compensation elements in the sprocket act like a cushion, absorbing the power pulses from the engine.

  • Motorcycle feels more refined and is quieter while accelerating, shifting and cruising
  • Sprocket (Black), Bowl (Cast Aluminum)
  • Kit includes sprocket, compensator bowl, and installation hardware

Fits '07 Touring (except Japanese) models equipped with Original Equipment and Harley-Davidson® accessory wheels. Will not fit with 80-Spoke Laced Wheel P/N 42954-04, Polished Spun Aluminum Disc Wheel P/N 43760-03 or Slotted Six-Spoke Wheel P/N 43932-02 (chrome) or 43933-02 (black).

When ordering aftermarket wheels, would I now specify for an 08 model rear wheel for proper fitment?

I have 2007 road king classic and am confused on what to specify for model year with IDS kit installed.

How can I tell if my '07 flhtcu already has the IDS installed?

Asked by: Erin
Hey Erin, The IDS didn't start becoming stock until '08. This will make a big difference in the ride on your '07 Ultra. Definitely a good investment.
