Fitment and Product Information: Pistons FHR Coated Forged 4032 Aluminum Flat Top with Two Reliefs 4.030 in. Bore 0.927 in. Wrist Pin GM LS 6.0/6.2L Set Brandname: KB Performance Pistons-ICN Part Number: IC9991C.030 Product Details: ICON FHR Series GM LS pistons 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. 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 Specs: Part Type: Pistons Product Line: ICON FHR Series GM LS Pistons UPC: 800745256140 Piston Rings Included: No Bore (in.): 4.030 in.
