The HobbyStar 550 4-pole brushless motor is a perfect high-torque, high-performance powerplant that is ideal for 4x4 1/10 RC trucks. This motor has a lot to offer including: comes in a standard 550 size, 4 poles for lots of torque, plug and play with most RTR brushless speed controls and is very affordable! The motor comes ready to bolt to the motor mount using standard M3 machine screws, and the 12AWG silicone wires with pre-installed 4.0mm gold-plated bullet plugs hook up to the ESC for an easy no-solder connection.

In general, the higher the KV the faster the motor is but may have slightly less torque than a lower KV. This 4300KV motor is plenty fast and is for 2S only.
