Precision motor offset for tuning and setup

The 3RACING 540 Motor Spacer CRA-108 is intended for builders who need repeatable motor positioning on Crawler Ex Real platforms. The 7mm offset simplifies setting accurate pinion to spur engagement during competitive setup work.

Setup guidance for competitive use

Use the spacer to establish a consistent baseline motor location when testing pinion sizes or drivetrain changes. After fitting, verify mesh, check bearing endplay, and confirm motor mounting torque to maintain stable performance on the trail or in timed runs.

How does spacer use affect tuning repeatability?

By fixing motor offset, the spacer reduces a variable when swapping motors or pinions, helping you return to a known baseline for lap or obstacle tuning sessions.

Any impact on drivetrain friction to consider?

Proper spacing avoids pinion binding which can increase drag. Confirm free rotation of the drivetrain after fitting and before running to ensure efficient power transfer.

Recommended checks after install for competition use?

Check gear mesh, motor mounting torque and fastener security. Record settings so you can replicate the configuration across practice and event setups.
