New Factory Team machined pistons for the 12mm big bore shocks take performance to the next level.
Precision CNC machined pistons allow for the best fitment and concentricity with the shock body to improve handling and consistency. The new pistons are also tapered for independent tuning of compression and rebound.
Difference between tapered and flat pistons
For example, a tapered piston with the taper facing down will travel faster in rebound than it will in compression, allowing the user to tune the rebound and compression movement independently.
Piston Hole Size
Piston Hole Count
By changing the number of holes in the piston, a similar damping level can be achieved with different amounts of "pack." Pack is the feeling of hydraulic lock in a shock when the fluid flowing through the holes reaches a certain speed. It can be used to keep a car from bottoming out during harsh landings.
