Description
ICON Pistons & Rings — Pontiac 488-495 Stroker
4.200" Bore (+.075") · 4.500" Stroke · -16.8cc Dish · Set of 8 with Rings
ICON pistons are forged 2618-equivalent premium alloy from United Engine & Machine, the same shop that builds Keith Black. They are the value-forged answer for a Pontiac that has outgrown a cast or hypereutectic piston — a healthy hydraulic roller street engine, a bracket car, or any build where detonation and heat are a real possibility.

What You Get
- Eight ICON forged pistons
- Matched 1/16, 1/16, 3/16 ring set
- .990" x 3.000" wrist pins and locks

Fitment & Installation Notes
- Uses the .990" (big-block Chevy) wrist pin diameter.
- Standard bore is based on 4.125"; +.030" nets a 4.155" bore.
Before you order: measure your finished bore before buying an oversize. Confirm chamber volume and deck height against your target compression ratio — crown volume alone does not set compression. Opened or installed pistons are not returnable.
