H&R Racing HRCH04 1/24 Adjustable RTR Chassis – 40K Motor & Fish Rubber Tires
High-performance rolling chassis ready for your 1/24 or 1/25 scale body.
The H&R Racing HRCH04 is a durable, adjustable 1/24 scale RTR chassis built for serious racing on commercial routed tracks and properly powered analog Carrera layouts.
With its 40,000 RPM HRML2 motor, adjustable wheelbase, aluminum rear wheels, Fish Rubber tires, and proven inline drivetrain, it makes an excellent foundation for NASCAR-style builds, vacuum-formed bodies, and hard plastic 1/24 or 1/25 model bodies.
We race these regularly with the CARS Club on our OmniSlotBox-enhanced Carrera track in Sherwood, Arkansas, as well as on commercial routed tracks. They are fast, smooth, durable, and easy to tune.
