Bring back solid, dependable performance to your 2002–2012 Chrysler/Dodge/Ram/Jeep 3.7L SOHC V6 (or select 1999–2013 non-HO 4.7L SOHC V8) with this single flat top piston with premium rings from LowPricedAutoParts – a precision standard-size replacement perfect for models like Ram 1500, Dakota, Durango, Liberty/Cherokee, Grand Cherokee, Commander, and even Mitsubishi Raider (2006–2009) sharing these PowerTech engines. This premium single-piston kit targets worn or damaged cylinders in stock-bore applications, helping eliminate oil burning, low compression, rough idle, or reduced power without a full engine swap. The kit includes one standard-size flat top piston paired with premium rings for superior sealing, reduced friction, and better oil control compared to basic options. The 1.252" compression height and coated skirt match factory geometry, ensuring proper deck clearance and piston-to-valve relationship in naturally aspirated SOHC setups (VIN "K" for 3.7L; "J,N,P" for non-HO 4.7L). It accommodates floating rods on the 3.7L (or press/floating on the 4.7L)—use this versatile single unit for spot repairs on 6- or 8-cylinder engines or order multiples for a complete refresh, great for work trucks, SUVs, or daily drivers. This is not a drop-in part for scored or out-of-round bores – professional cylinder honing (if needed), precise measurement, and blueprinting are essential for best results. Always confirm bore diameter and piston-to-wall clearance (typically 0.002–0.004" per common Chrysler PowerTech guidelines—verify with piston/ring manufacturer specs) during assembly to achieve ideal ring seal, oil pressure, and engine life. Verify your exact year, engine code, and application before ordering.
