Kyosho IF114B Rear Hub Carrier Inferno GT MP777

This is the rear hub carrier for Kyosho's Inferno GT and MP777 era platforms, supplied with its spacers.

The rear hub carrier holds the rear wheel hub and bearings and connects them to the suspension arms. It is where rear toe-in is set, and rear toe is one of the settings that most directly controls how stable the car feels on power. More toe-in plants the rear end and makes it track straight under acceleration; less frees it up and lets the car rotate more willingly. Because that geometry is built into the part, the carrier you fit is a setup decision as much as a repair.

Structurally it takes everything the rear wheel receives, which on a 1/8 car means every landing and every impact with a rut or pipe. A cracked carrier changes rear geometry on that side only, so the car pulls under power and behaves differently through left and right corners.

The B designation supersedes the original IF114. Dealers list fitment across the Inferno MP-7.5 and MP777, Inferno GT and GT2, Inferno NEO, and the ST-R and ST-RR truggies.
