ICON FHR Series pistons for GM LS offer premium, custom options in an "off the shelf" option for your LS-family engine. FHR (Formed Head Relief) pistons have valve reliefs that are formed in as the piston blank is pressed into the die, creating a stock, but light forging. Many of the domed models are solid which allows tailoring the dome height for a specific compression ratio. They are constructed from high-strength, forged 4032 aluminum alloy for increased durability while maintaining tighter piston-to-wall clearance for increased cylinder sealing, lower cylinder wear, and stock-like noise levels, making them ideal for street and lightly boosted applications. ICON FHR pistons for GM LS also feature: * Mini grooves allow an overheated piston that contacts a cylinder wall to transfer heat to the wall. Friction is also reduced over a solid ring land. * Accumulator grooves provide a reservoir area for gases that pass by the top ring. Pressure is reduced between top and second ring to help stabilize flutter and maximize ring seal. * 0.030 in. offset wrist pins * Round wire locks * M42 skirt coating

ICON pistons have introduced a new forging line: the FHR (Forged Head Relief) Series. This new line features VMS 75 alloy, true arc-style lock rings, broached pinholes, breakthrough oil returns, and 5/64 in. ring packs—all designed to be easy on your wallet! In addition, most flat-top and dish applications are available in an offset pin design, which will help to quiet those street motors. The included piston rings will seal mild to high-compression engines, help to protect against oil blowby, and feature standard ring end gap for an easy installation.

ICON Premium forged pistons are designed to be application specific and are made from either 4032 or 2618 aluminum. 2618 aluminum has a lower silicon content and is better suited for engine combinations with high compression or a power adder. A byproduct of having a lower silicon content is an increased rate of thermal expansion. Because of this, pistons made from 2618 require more piston-to-cylinder wall clearance than their 4032 counterparts. ICON Premium forged anodized pistons include all the features of an FHR piston, with the addition of an anodized top ring groove and crown, precision CNC-machined valve reliefs and crown features, pressure fed pin bore oiling, and skirt and pin boss struts for increased strength and durability. ICON Premium pistons are built in a variety of compression ratios and are available for a wide range of engine types. Select the ones designed for your vehicle. Additional features: * Mini grooves * CNC-machined valve reliefs and crown * Diamond CNC-turned skirts * Accumulator groove * Dual forced pin oiling * Lateral gas ports on high-compression designs * Spacer rings provided for shorter compression height pistons

If you are looking to step your engine program up to the next level, ICON Elite forged pistons and ring kits have exactly what you are looking for. Made exclusively from 2618 aluminum, the Elite Series pistons are purpose built from top to bottom to perform consistently in extreme conditions. ICON's Elite forged pistons feature their Line2Line adaptive skirt technology coating that reduces friction between the piston and cylinder wall, while providing additional protection at start-up. They come standard with an anodized top ring groove to greatly reduce micro-welding that can occur under detonation conditions, and an anodized piston crown to help focus the heat in the piston crown and improve combustion efficiency. ICON Elite forged piston and ring kits include pistons and ring stack. Select the Elite kit designed for your build. Additional features: * Upgraded wrist pin * Mini grooves * CNC-machined valve reliefs and crown * Diamond CNC-turned skirts * Accumulator groove * Dual forced pin oiling * Lateral gas ports on high-compression designs * Spacer rings provided for shorter compression height pistons
