Fit the 3Racing S3M165 - SAK-F78B to Your KIT-FFEX

The 3Racing FFEX S3M165 - SAK-F78B belt is manufactured for the KIT-FFEX Belt System to keep power delivery smooth and predictable under varied driving loads. It helps maintain consistent drivetrain behaviour across sessions.

Strength and Lifecycle

With a focus on endurance, the S3M165 belt stands up to repeated heat and load cycles common in club and championship running. The design reduces stretch and helps preserve original setup characteristics.

Installation and Practical Use

Designed to match KIT-FFEX pulleys and spacing, the S3M165 fits with minimal fuss and holds reliable tooth engagement. It is an effective choice for replacing an ageing belt or as part of a maintenance refresh.

Does the S3M165 - SAK-F78B need break-in time?

A short break-in of a few controlled runs helps seat the belt. Check tension after a brief session and adjust if needed for consistent performance.

Will this belt reduce drivetrain noise?

When correctly tensioned, the belt can run quieter than worn or stretched belts. Proper alignment of pulleys also helps limit noise and vibration.

Should I check belt tension after harder runs?

Yes. High load sessions can alter tension slightly, so a quick check before the next run preserves consistent feel and reduces risk of slippage.
