Overview
Eliminate motor mount flex and improve drivetrain reliability on your Traxxas Rustler 4x4, Slash 4x4 LCG, or Rally with the Hot Racing Aluminum HD Bearing Motor Mount. CNC-machined as a one-piece unit from heavy-duty aluminum and anodized in clean blue, this motor mount features an oversized 10x19x5mm ball bearing — significantly larger than the stock 10x15x4mm bearing — for far better drivetrain support under high horsepower.
The result is a more rigid, more durable motor mount that handles aggressive brushless setups without complaint, and works with both slipper and center differential transmission configurations. Compatible with telemetry RPM sensor systems.
