Product Description:
⚠️ Technical Build Warning (Read Before Purchasing)
This is a highly specialized Extreme Duty "Turbo Tuff" Dish Piston set specifically engineered for 3.4L Stroker setups (94mm stroke) featuring a -6.00cc dish volume. Running this on a stock 86mm crankshaft will entirely alter your target deck clearance, displacement, and compression ratios:
-
3.4L Stroker Setup (94mm Crankshaft + 45cc GTE Head): Yields a perfectly engineered 10.0:1 Compression Ratio. It is optimized specifically to withstand massive boost levels on upgraded stroker blocks.
-
2JZ-GE Heads / Stock Cranks: Do not use this piston for standard 3.0L factory rebuilds. The compression height is shortened intentionally to accommodate the longer 94mm stroke.

Premium Materials & Manufacturing Features
-
2618 Aircraft-Grade Forging: High-silicon alloy built to withstand extreme cylinder temperatures and aggressive ignition timing without fracturing.
-
Factory Moly-Coated Skirts: Features an advanced anti-friction skirt coating straight from Manley Performance to protect walls during cold start-ups and decrease friction.
-
One-Fixturing Machining: Unique manufacturing process ensuring the ring grooves are perfectly square to the piston skirt for optimal ring seal and maximum horsepower retention.

Installation Notes
-
Machine Shop Requirement: Because this requires an 87.00mm bore, your engine block must be bored and honed +1.00mm over factory size. Always supply these physical pistons to your machine shop so they can measure exact skirt-to-wall clearances before machining.
