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.

Improved Racing CCS Oil Catch Can Kits

Improved Racing set out to design the best air-oil separating catch cans specifically for the factory supercharged vehicles. Focused on three simple design goals: maximized efficiency, durability, and ease of use, the development of the CCS oil catch cans happened over several years and included ANSYS Fluent CFD simulations, extensive bench tests, and on-vehicle street and track tests. Final prototype testing also included a 9-month beta testing program in collaboration with various road racers, drag racers, and drifters. The CCS's design maximizes air-oil separation efficiency, resulting in a peak separation efficiency of 85 to 90 percent. For comparison, none of the competitor's catch cans tested showed a peak efficiency of more than 60 percent. The CCS oil catch cans are durable, made from high-quality, reliable components and, as with any Improved Racing product, nothing will vibrate loose or come apart under racing conditions. Keep contaminants out of your intake to increase octane and keep your engine clean with Improved Racing CCS oil catch can kits. Select the kit specifically designed for your application needs. Product details: * The CCS features tangential entry port for cyclonic separation for maximized efficiency—separates as much vapor from crankcase blow-by fumes as possible with minimal restriction * Other features include stainless steel filter with multiple filter seals, primary seal, bell mouth exit plenum, anti-splash-back funnel with spiral drain groves, and 7.0 fluid oz. or 3.5 fluid oz. reservoir * Quick-turn, easy to service reservoir * Includes mounting bracket and custom made, emissions friendly, quick-connect lines—designed specifically for factory supercharged vehicles * CNC-machined aluminum bracket locks into position every 22.5 degrees—allows for different mounting options specific per the make and model vehicle to offset catch can from engine to clear larger engine covers, evap lines, etc. * Optional drain kit (sold separately) is available to allow for remote draining without removing the catch can—because engine bay fitment is tight on specific vehicles * Fast and flexible mounting bracket system for installation/removal and positioning—tool-free bracket nut can be removed without tools, or snug it down with 5/8 in. wrench * No sight glass needed—just push-up and twist a 1/8th turn to remove the reservoir and look inside, no more fumbling, or endless unscrewing to remove the reservoir * A powerful wave spring keeps the reservoir locked in place—included positive safety lock clip is also included just in case you want to be absolutely sure the reservoir cannot be removed

COMP Cams Thumpr Hydraulic Flat Tappet Camshafts

COMP Cams is bringing the musclecar sound back, and it's nastier than ever! Few things grab our attention at a car show or cruise-in like a thumping, high performance idle. In fact, one of the most frequent questions from customers is, "What camshaft will give my car that mean-sounding idle?" For the performance and sound you demand, COMP Cams engineers introduce the Thumpr camshafts—a new series of hydraulic flat tappet cams. The lobe profile and grind characteristics of Thumprs use a combination of early exhaust valve opening, long exhaust duration, and a generous amount of intake and exhaust overlap—to maximize the rough-idling characteristics of the cams. They give you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in several grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range.

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
