Kyosho IF131 Center Differential Mount Inferno

This is the centre differential mount for Kyosho's Inferno platform.

The centre diff mount is the housing that holds the centre differential in position on the chassis and keeps it aligned with the front and rear driveshafts. It is one of the more heavily loaded structures on a four-wheel-drive car, because all of the engine or motor torque passes through the centre diff on its way to both axles, and the mount has to hold that diff in exact alignment while absorbing the shock loading of landings.

When a mount cracks or distorts, the symptoms show up in the drivetrain rather than as an obvious structural failure. Gear mesh goes inconsistent, you start hearing noise under power, and the diff bearings and outdrives wear far faster than they should. It is worth inspecting any time the car is apart after a heavy crash.

This is the genuine Kyosho part. It originated on the Inferno MP-7.5 and MP-777 and Kyosho still lists it for the Inferno NEO 3.0, NEO ST 3.0 and NEO 4.0, Inferno GT2 Race Spec and GT2 VE Race Spec, and the Psycho Kruiser VE 2.0.
