TRX-3975R Traxxas Motor, Titan 550 Brushed 21-Turn Reverse Rotation (14V)

The Titan 550 reverse-rotation motor is the same fan-cooled 21-turn 550-size brushed powerplant as the standard 3975 — but wound for reverse rotation. This is the stock motor in TRX-4 Crawler vehicles and the correct replacement for dual-motor applications where the second motor must spin in the opposite direction. Wire leads and bullet connectors come pre-installed. Pinion gear and mounting hardware are not included.

What’s Included

• (1×) Titan 550 reverse-rotation brushed motor with pre-installed wire leads and bullet connectors

What’s Not Included

Pinion gear and motor mounting hardware — not included, sold separately.

Fitment Note

Fits many Traxxas electric vehicles requiring a 550-size reverse-rotation brushed motor. Most commonly the stock motor in TRX-4 Crawler vehicles and as the second motor in dual-motor E-Maxx platforms. Consult your vehicle’s manual or parts diagram to verify fitment before ordering.

Key Features

• 21-turn reverse-rotation brushed motor — 550 size, fan-cooled

• 30% longer armature than a standard 540-size motor for greater low-end torque
