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

ATI offers two different versions of their bolt-on style SFI bellhousings, including ATI SFI Standard bellhousings. The Standard versions bolt onto the face of the pump and the case finish is not as critical. The direct-fit versions indicate on the outside diameter of the pump and require precise machining. When you want the standard-style, choose the ATI SFI Standard bellhousing best suited for your application.

Patented ATI Super Damper standard harmonic balancers are the only crankshaft dampers designed exclusively for high performance engines. Inner and outer shells are available in aluminum or steel, and contain a steel inertia weight. The inertia weights have six (2-ring design) or eight (3-ring design) computer-machined grooves to retain the proper durometer O-rings (dyno tested for each application). Whether you race or just drive on the street, ATI harmonic balancers are the perfect choice. Features include: * Eliminates torsional crankshaft vibrations * Exceeds SFI 18.1 specs * Black zinc chromate finished * OEM equipment on a variety of crate engines * Tunable, rebuildable, and extremely efficient at all rpm * Laser-engraved 360 degree timing marks * Supercharger and power steering drive pulleys available for some applications

Made on state-of-the-art CNC equipment, ATI SFI flexplates are double MIG/TIG-welded with certified American-made materials that far exceed SFI specs for safety. They're manufactured and toleranced from actual OEM drawings to ensure precise fit and location. Each is quality-inspected to exceed the flatness and runout tolerances of the OEM units. They are also precision-balanced on Hines digital equipment with a resolution of 1/10 oz. per inch. Available in dozens of configurations, ATI SFI flexplates can be ordered for fitment on vehicles covering every decade since the mid-1950s.

ATI torsional input shafts work like a torsional spring bar--twisting and returning to totally eliminate breakage, while reducing shock loads to the gear train. They are manufactured from top-quality 300M or Vasco for maximum durability. Available for GM Powerglide or TH400 splines, these ATI torsional input shafts will add some reliability to your drivetrain.

ATI Super Damper harmonic balancer shells are specifically designed for high-rpm engines. Their proven elastomer is engineered and tuned to eliminate damaging crankshaft harmonics that cause parasitic horsepower loss. These damper shells are built to all-but-eliminate worn parts and timing problems. These are the shells only and must be used with an ATI hub, which is sold separately. Order the model recommended for your vehicle application.

ATI Superplate Flexplates were developed in ATI's tradition of staying ahead of the rampant increases in horsepower that are common in the performance industry today. Superplates are manufactured from a super-strong material to withstand thousands of cycles. They are laser-machined rather than stamped to avoid the heat and stress stamping inflicts. The crank bolt holes are bored in position to exacting tolerances in both size and location on CNC machines. Superplates use the grip length of the crank bolts as dowels to prevent the plate from moving under high-torque conditions. Unlike billet plates that violate the "flex principle" of a flexplate, Superplates flex like OEM plates, absorbing the numerous machining tolerances that exist in our non-exact world. Additional features of ATI Superplate Flexplates include: * Neutral-balanced for use on internally balanced engines * Exceed SFI 29.1 and 29.2 ratings * 90,000 lbs. tensile strength * 80,000 lbs. yield strength * Six or eight crank bolts (varies by application)

ATI 300M intermediate shafts are part of the company's extensive line of automatic transmission input shafts. Grade 300M is a high-strength, low alloy steel. Torsional input shafts work like a torsional spring bar, twisting and returning to totally eliminate breakage while reducing shock loads to the geartrain. The intermediate shafts are designed to fit either the Powerglide or TH400 splines. Order the replacement recommended for your application.

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.

ATI Compu-Flow forward manual valve bodies are available with the same features as the reverse manual units, except for the standard OEM shift pattern (P-R-N-3-2-1). Engine braking is available in all gears. The forward valve bodies provide a generally slower ET for drag racing, since the band or clutches are on in low gear.

ATI Compu-Flow reverse manual valve bodies shift opposite of the OEM units, away from neutral when up-shifting (P-R-N-1-2-3). There is no automatic shifting. They will remain in the selected gear, allowing street-driven cars to move off in 2nd or 3rd gear in slippery conditions. The governor and related components are eliminated, as well as throttle pressure, cables/vacuum lines, and linkages. All units freewheel if you lift in low gear; there is no engine breaking. (Note--all turbo units freewheel in 2nd gear, except #353400 for the T-350.) These valves are not recommended for the Powerglide, since it must pass through low to get to neutral.

ATI Super Pump front pumps are CNC-machined from billet aluminum or permanent-mold aluminum castings for precision and durability. Re-engineered lubrication circuits allow for increased flow volume in all critical areas. ATI increased the thickness of the pumps to improve oil pressure and volume at low rpm, resulting in a cooler-running transmission and converter. Features: * Superior pressure * Improved trans-brake hold * Prevents stator tube spinout

Factory dampers and non-dampened pulleys offer no protection to high performance engines. ATI Super Damper sport compact harmonic balancers provide the balanced dampening of torsional crankshaft vibrations at all rpm levels. The street versions have both OEM serpentine groove locations and are very close to OEM size. The smooth-shell race version dampers are designed for high performance race use. Both dampers come with laser-etched timing and exceed SFI 18.1 Safety Certification standards for competition use.

ATI now offers a custom crank trigger shell option, eliminating an additional pulley being bolted to your damper. If you already own an ATI Super Damper, you can just change the outer shell to the trigger. ATI can place any number of magnets in the outer shell at whatever degree marks you wish. These aluminum crank trigger shells will work with "Flying Magnet" pickups and other trigger sources. Order the model best suited for your application. Note: When placing your order, please have the desired quantity and location of magnets ready. Additional charges for extra magnets apply.
