Crower Stainless Steel Shaft Mounted Rocker Arm Systems

For those of you that feel most confident running a steel-based valve train, look no further than the collection of Crower stainless steel shaft-mounted rocker arm systems. Every configuration has been rigorously scrutinized to offer extreme rigidity and accuracy while optimizing the moment of inertia phenomena condition. Crower engineers made ease of installation and maintenance a top priority--so you'll never waste a moment when time is critical at the track. These stainless steel shaft rocker systems are a perennial favorite of dirt late models and marine endurance competitors. Sustained high temperatures have little effect on the strength properties of stainless steel so components made from this material typically have a longer life expectancy than similar components made from aluminum. All Crower shaft mount rocker arms are available with Crower's needle bearing roller tip option. They greatly reduce friction for added horsepower and decreased valve guide and valve stem wear. The lighter tips deliver greater valve control for increased rpm and improve valve spring longevity by decreasing heat compared to traditional non-needle designs.

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
