Wiseco Pro Series LS7 Piston Kit

Designed to work with OEM connecting rods, the Wiseco Pro Series Piston is offered in stock 4.125" bore or slightly larger 4.130" bore for rebuilds.  HPR has extensive history with Wiseco and have found them to be one of the best piston manufacturers in the market today and our first pick for most builds.  All kits include piston pin, locks, and ring set unless noted otherwise.

Some of our forged pistons offer our new ArmorGlide™ skirt coating, which is the result of testing, development, and benchmarking through Wiseco’s rigorous in-house dyno program. The outcome is the ultimate in skirt coating toughness, lubrication, and bond technology working together to minimize friction, maximize horsepower, and provide improved wear resistance. Not only is ArmorGlide™ a high-tech lubricant that reduces friction, but it also allows the piston to be fitted tighter within the bore allowing a better ring seal and reduced noise from piston rock.
