How to find the right RC Vehicle Shock Pistons AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in RC Vehicle Shock Pistons
- Shock system match
- The piston outer diameter must match the shock bore, and its center hole must match the shaft diameter. A loose piston bypasses oil, and one that is too large binds in the body.
- Hole count and diameter
- Fewer or smaller holes give more damping. More or larger holes give less. The hole area mainly sets the damping, with oil weight adjusting it further.
- Flat vs tapered
- Tapered or angled holes give different compression and rebound damping. Flat pistons damp both directions equally. Racers use tapered pistons to tune landing response separately from rebound.
- Machined vs molded
- Machined pistons give more consistent hole sizes from shock to shock. Left and right shocks must match, or the car will handle unevenly.
Brands that matter
- Team Associated: Wide range of hole counts and tapers for its shocks.
- Team Losi Racing: Tuning pistons for its racing shocks.
- Traxxas: Piston sets in multiple hole sizes for its shock lines.
- Kyosho: Option pistons for its racing shocks.
What to avoid
- Mixing piston types between left and right shocks on the same axle
- Changing pistons and oil weight together when you are trying to diagnose handling
Questions
Should I change pistons or oil weight?
Oil weight is easier and changes damping in all conditions. Pistons change how damping responds to speed, mainly on landings and over bumps.
