Mahle LSX Combo PowerPak Piston and Ring Kits

Mahle Motorsports offers GM LSX Combo PowerPak piston and ring kits, designed for high-output, naturally aspirated, power-adder applications. These Combo PowerPak kits offer the best of strength in an all-forged aluminum alloy piston to allow for increased detonation resistance, and a combination valve pocket design that will cover LS1, LS3 and LS7 cylinder heads. Features and benefits of these LSX Combo kits include: * PowerPak pistons are all dual-coated with Phosphate coating to provide the piston's characteristic gray appearance (dry lubricant provides a lubricant film protection in the pin bores and ring grooves) * Each slipper skirt is treated with Grafal; Mahle's proprietary coating to reduce wear, drag, scuffing, friction, and piston noise * If the valve pocket layout is unknown when assembling the short block, these pistons will accommodate an LS1-style cathedral port, LS3-style rectangle port, and also LS7-style cylinder heads * With listings for flat tops, dishes, and domes, these Combo PowerPak piston kits will not lock you into a single configuration, allowing for changes that can be made, as needed * Compression ratios are available from 10:1 and cruise all the way up to 14:1 with bore options ranging from 4.000 in. to 4.185 in.

ICON FHR Series Pistons for GM LS

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

Total Seal TSS Street Piston Rings

You won't lose horsepower due to blowby when you install Total Seal TSS Steet piston rings. The secret is in Total Seal's gapless second ring technology. This arrangement uses an oversize cast iron main ring, plus a chrome-faced secondary ring that overlaps the main ring's end gap. This interlocking design forms a gapless seal, which gives Total Seal TSS Steet rings a miniscule leakdown rate of just 2 percent or less, compared to the 8 to 10 percent rate for conventional gapped rings. They're perfect for street or mild race applications with 10.5:1 or lower compression ratios.

ICON Premium Forged Anodized Pistons

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
