King 2.5 Race Series 4 Port Piston

New 2.5" King Prerunner series 4 port piston. By adding an extra port to the already king 3 port piston, this four port piston will help distribute the force on the shim stack, which will in turn gives you a better transition through sharp hits for a better ride. Rebound ports have been brought inward to accept 1.60 shim to give you the option of more rebound flow for high speed off roading while still being able to have the option of adding 1.75 shim for less flow. These pistons are designed for steel wear bands only. Priced for one piston only.
