Thread: TRW Pistons Question

L2417 flat top pistons with a 3.5 cc trough. Use 0.004" piston to wall clearance measured at the pin centerline. Forged high-performance pistons suitable for beating on.

Choose your combustion chamber size across the top and see the static compression ratio of these pistons under the chamber number....
