Kyosho UM517GM Ultima Motor Plate

The Kyosho UM517GM Motor Plate is a genuine aluminum motor mounting plate for Kyosho's 1/10 scale 2WD Ultima family. The motor plate is a critical structural part: it carries the motor, holds it in precise alignment with the transmission, and acts as a heat sink pulling temperature out of the motor can during long runs. A flat, true plate keeps gear mesh accurate between the pinion and spur, which protects the drivetrain and keeps power delivery efficient.

This anodized aluminum plate is the standard replacement for the Ultima RB5 SP2 WC and serves as the direct service and option part for the RB5, RT5, SC-R, and DB series, superseding the earlier UM517 part number. If your plate has been gouged by a thrown pinion, warped from a crash, or stripped at the mounting holes, a fresh factory plate restores exact motor alignment. Package includes one motor plate.
