KB Performance Pistons have everything you want in a performance piston: the strength to withstand high compression and heat, lightweight design, and a price that fits your budget. Most are forged from high-silicon aluminum alloy, then CNC-machined and heat-treated for strength up to 30% greater than stock. They’re also engineered with race-ready features like high upper compression-ring locations, gas-accumulator grooves, drilled oil returns, and spiral-lock retainer grooves. We also carry Keith Black Silv-O-Lite pistons for high quality in a lower-silicon stock replacement piston.

KB Performance hypereutectic pistons are made from 390 aluminum alloy and heat-treated to T6 standards, which makes them 30 percent stronger than ordinary untreated hypereutectics. Their 100 percent CNC-machined crowns, high upper compression-ring location, gas-accumulator groove, drilled oil returns, and spiral-lock retainer grooves make these pistons outstanding for performance applications. They have a lightweight, rigid-rib skirt design that stabilizes the piston in the bore. All of this adds up to pistons that fit tighter than forged types, provide improved oil control, reduce blow-by, increase ring life, eliminate cold start-up knocking, and won't cost you an arm and a leg! Thousands of models are available—find the set and options designed for your vehicle and engine application.

KB Performance Hyper piston and ring kits are offered for a wide range of applications from street and towing to marine and race. The kits feature pistons cast from 390 hypereutectic alloy heat-treated to T-6 standards to make them stronger. The pistons also feature fully machined crowns and valve pockets. KB hypereutectic pistons come in several head designs, as well as standard and oversized bore sizes. All KB Hyper pistons are lightweight to improve throttle response and rpm changes, while still being strong enough to withstand high compression and high temperatures. KB Performance Hyper kits (KT) are completed with piston ring sets containing top rings of moly-coated cast iron (M) or ductile iron (D).

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.

Get the most from your hard-earned dollars with Silv-O-Lite hypereutectic pistons. These pistons utilize aluminum alloy high in silicon for greater strength plus scuff and seizure resistance. Silv-O-Lite pistons have improved groove wear and resist cracking in the crown area where operating temperatures are severe. Silv-O-Lite hypereutectic pistons feature reinforced top lands and their proprietary process of diamond finished skirts. These aftermarket pistons are available for many applications from your light truck to your auto or import. Spend wisely and choose replacement pistons that will work hard for you--Silv-O-Lite hypereutectic pistons.
