Performance oriented belt tension mount for Sakura D4

The 3Racing SAK-D4815/BK is a purpose built aluminium belt tension mount engineered for the Sakura D4 chassis. Machined aluminium construction provides a rigid, low flex mounting surface that helps maintain consistent belt position and reduces variable drivetrain lash under acceleration.

Engineering benefits of the aluminium design

Aluminium delivers a high stiffness to weight ratio, which improves belt routing stability without a significant weight penalty. The mount reduces lateral movement and limits belt fatigue, extending service intervals for pulleys and belts in race conditions.

Fitment, setup and tuning guidance

Designed to match Sakura D4 mounting points, the 3Racing unit installs with standard hardware and requires only basic tools. For competitive setups, verify belt alignment and check tension increments across temperature changes to keep lap times consistent.

How does this affect belt stretch on long runs?

The rigid aluminium mount reduces belt oscillation and distributes load more evenly, which helps limit belt elongation over extended running compared with flexible stock mounts.

Any recommended torque values?

Use manufacturer recommended screw torque for aluminium-to-chassis connections and recheck after initial runs; avoid overtorque to prevent chassis distortion.

Is this compatible with high torque motor setups?

Yes, the aluminium mount is better suited to higher torque applications than many stock plastic parts, but confirm belt and pulley condition when increasing motor output.

Tuning tips for race day?

Check belt tension after each session and note any change across temperature. Small adjustments to tension can fine tune traction and throttle response for different track surfaces.
