How It Works

Kit to Build

01
Order Your Kit
Select your platform. All kits include forged rods, pistons, ARP hardware, wrist pins, and ring sets. Ready to ship worldwide.
02
Machine Your Block
Take your block for bore and hone. We recommend 0.002″ overbore for oversized pistons. We advise on all specifications.
03
Install & Build
Drop-in installation on a freshly machined block. Compatible with YPG Stage 4 turbo kits and all supporting modifications.
04
Tune with YPG
Pair your forged build with a YPG ECU calibration mapped for your engine, fuel type, and power target. Stage 2 through Stage 4.

Build Once.
Build It Right.

Every YPG forged internals kit is built to world record specification. Stop guessing on power limits — start with a foundation that won't let you down.
