Belt Tension Control for FFEX Using the 3Racing SAK-F78A

The 3Racing FFEX Belt Tension Post - SAK-F78A is a targeted upgrade for KIT-FFEX chassis that helps the belt retain correct tension under load. By reducing slack and maintaining consistent tension the post aids driveline efficiency and makes vehicle behaviour more predictable when pushing hard on track.

Will this change my handling?

The post itself focuses on belt tension rather than suspension. Improved tension can translate to crisper throttle response, which may affect how you tune differential and throttle trims.

Can I fit it trackside between heats?

Yes, installation is usually quick with common hand tools, so it can be fitted during event pit time if you carry drivers tools and spare fasteners.

Are there upgrade parts that pair well with this post?

Complementary upgrades include checking pulley condition and considering a higher quality belt if you are addressing slip or stretch as part of a wider drivetrain tune.
