These 8 hole shock pistons are made using Delrin material. This unique design allows for the same pack on the down stroke. 

this newer model is using  a 1 mm oring and 7 slots on the bottom for dampening.

our testers have found that this oring has a lot better response.

On the rebound the shock oil puts pressure on the “Oring” to slow dampening and helps eliminate blow by of the shock oil around the piston.

MOUNT Slots go down to slow rebound.( recommended)
