YZ-4 Hard Center Tensioner Post Upgrade - Yokomo Z4-CTP for YZ-4  [Z4-CTP]

Durable centre tensioner designed for YZ-4

The Yokomo Z4-CTP hard center tensioner post is produced for the YZ-4 family of 1/10 4WD off-road cars and acts as a direct replacement for the factory unit. It is intended to control center belt or cable tension within the vehicle's drivetrain layout.

Rather than changing the suspension geometry, the harder post increases resistance to deformation under load, which can reduce drivetrain lash and help keep belt tension steady during heavy running. Opt for this hard post when you need a firmer preload compared with softer alternatives.

Fitting on compatible YZ-4 frames is simple: place the post into the original position and secure it with the stock mounting hardware. Confirm belt alignment and free rotation of drivetrain components before the first run, and avoid overtightening mount fasteners to protect threads and parts.
