Race-focused mono shock upgrade for F113 chassis

For competitive tuners the 3Racing F113-121A aluminium mono shock body offers improved damping consistency and reduced friction. Precision manufacturing and a Teflon finish support repeatable setup changes and reliable track performance.

Technical advantages of a Teflon finish

The Teflon coating reduces stiction between moving surfaces, improving low-speed compliance and mid-stroke response. This delivers crisper transient behaviour and more accurate rebound control for setup tuning.

Compatibility with standard F113 geometry

Manufactured to fit F113 mounting dimensions, the shock body allows direct installation into existing dampers without altering travel or mounting angles, preserving baseline geometry for comparative tuning.

Tuning notes for racers

Expect slightly altered seal break-in and marginally reduced internal friction; pair the body with matched pistons and oils to extract consistent lap-to-lap performance. The component is suited to teams and advanced hobbyists refining damping profiles.

What piston sizes work best with this body?

Use piston diameters and hole counts that match your target damping curve; low hole counts with heavier oil give ramped feel, while multiple small holes suit smoother transitions.

Which shock oil weights should I test first?

Begin with oils you use on similar aluminium bodies and adjust in small steps; the Teflon finish can make lighter oils feel more controlled, so test 5 to 10 wt differences for tuning.

Any recommended sealing practices?

Fit new high-quality seals and perform a controlled break-in. Inspect shafts and seal surfaces for burrs before assembly to ensure consistent sealing and minimal friction.
