ATI Super Damper Serpentine Series Harmonic Balancers

ATI Super Damper Serpentine Series harmonic balancers are patented and feature grooves for serpentine belts machined into the outer damper shell. The dampers come with six outer grooves for standard OEM drive systems—but eight and 10 grooves are available for supercharger or turbo applications. Serpentine dampers are offered in a variety of diameters, and crank hubs may be fitted with a 6-groove serpentine pulley to drive external oil pumps or vehicle accessories. The Serpentine Series Super Dampers fit all ATI GM-front crank hubs and can be adapted to many engine combinations, providing maximum flexibility. They're available in steel or lightweight, hardcoated aluminum. Features and benefits: * Eliminates torsional crankshaft vibrations * Exceeds SFI 18.1 specs * Black zinc chromate finished * Tunable, rebuildable, and extremely efficient at all rpms * Laser-engraved 360 degree timing marks

Fluidampr Harmonic Dampers

Using only three parts (a laser-welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two), SFI-approved Fluidampr harmonic dampers can control all crankshaft vibration--not just a limited frequency range. As a result, you get reduced wear on the main bearings and timing gear, more stable valvetrain operation, and less chance of crank failure.

COMP Cams Sportsman Solid Roller Lifters

COMP Cams Sportsman solid roller lifters feature premium-quality, high-value components designed for sportsman and professional racing, along with high-end street machines. They're available in both needle-bearing and bushing configurations. Each design features two pressurized EDM oil feeds, as well as an edge-orifice feed to the wheel. This delivers a more reliable oil feed than most competing options. COMP Cams Sportsman solid roller lifters are also designed with a shallower oil band than competitors' versions for increased strength and rigidity, while internal machining helps to reduce weight. The body utilizes a skirted wheel that strengthens the lifter ears, and the skirt also provides more contact area with the lifter bore for further lifter stabilization. In addition, staked axles eliminate clips and provide robust axle retention. This feature increases the stiffness of the lifter ears and helps to prevent the ears from spreading. The COMP Cams Sportsman solid roller lifters are built from 8620 premium steel for increased strength and wear resistance and they feature a captured, stainless steel link bar design. The lifters also utilize a tapered and slotted link bar tower for reduced weight and improved aesthetics. Choose the size and options tailored for your engine application.

ATI Super Damper Supercharged Series Harmonic Balancers

These Supercharged series dampers place the powerful protection of ATI Super Damper inside of the crankshaft blower pulley. Available in 66 to 77-tooth 8mm pitch, and 40 to 51-tooth 14mm pitch, these balancers eliminate torsional crankshaft vibrations and feature dual-keyway hubs. These balancers exceed SFI 18.1 specs, have laser-engraved 360 degree timing marks, and are finished in a black zinc chromate. Numerous pulley offsets are available to keep the blower drive as close to the engine as possible, reducing the bending moment to the crankshaft nose.

COMP Cams Ultra Pro Magnum Rocker Arms

Utilizing years of valvetrain design experience, the latest FEA stress analysis technology, and an exhaustive testing regiment (dyno and Spintron), COMP Cams engineering team left no detail to chance. Everything from casting techniques to valve spring clearance was scrutinized to ensure that Ultra Pro Magnum rocker arms not only lived up to the lofty standards of their predecessor, but also took stud mount rocker performance, stability, and value to a whole new level. The most noticeable advancement centers around their nearly unbreakable investment cast 8650 chromoly body. The arched, web-like design delivers a nearly 29 percent increase in strength and rigidity, while reducing the moment of inertia and optimizing the dynamic balance. The resulting rockers maximize lift and valvetrain control at high rpm. The increased retainer and valve spring clearances of the new design enable the use of large-diameter valve springs, retainers, and locks, without clearance or fitment issues. The new black oxide exterior finish offers a distinctive appearance, along with long-term corrosion resistance. The COMP Cams Ultra Pro Magnum rocker arms feature an oversized trunnion and precision-sorted needle bearings designed for use with high-load valve springs. These unique rockers also feature hardened roller tips for reduced friction and elimination of the valve stem "side loading" that causes premature valve guide wear.

Innovators West Harmonic Balancers

Innovators West harmonic balancers are a great investment for your street or race vehicle. These dampers feature lightweight billet aluminum covers equipped with free-floating wet friction clutch pack assemblies that utilize spring-loaded inertia rings to dampen crankshaft harmonics over a wide rpm range. The rings work in conjunction with clutches to provide outstanding dampening action. That action does generate some heat, and Innovators West uses a small amount of fluid inside that acts as a lubricant, as well as dissipates heat to the outer body. Backed by over 25 years of experience, Innovators West has produced high-quality SFI 18.1 certified harmonic balancers employing all American-sourced materials and fasteners. Choose the model designed for your vehicle and engine application. Innovators West harmonic balancers/dampers feature: * Billet 6061 aluminum case for lower reciprocating weight * Fully scribed 360 degree timing marks * Laser-engraved part number and SFI rating on back * Premium steel internal inertia rings * Stress-proof steel crankshaft hub * OEM bolt pattern and pulley register
