ATI SFI Flexplates

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 Superplate Flexplates

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 Crank Bolts

ATI crank bolts are engineered to provide maximum strength and reliability in high performance and racing engine applications where crankshaft retention is critical. Manufactured from premium high strength materials and precision machined to exact tolerances, ATI crank bolts are designed to maintain proper clamping force under extreme RPM, high load, and severe harmonics. When paired with performance dampers and rotating assemblies, these bolts help prevent loosening, fretting, and crankshaft damage that can result from inadequate fasteners. Built to meet the demands of serious street, track, and competition engines, ATI crank bolts deliver secure installation, consistent torque retention, and long term durability—making them a trusted upgrade for builders who refuse to compromise on engine integrity.

ATI Adapter Kits

Many racers would argue that a Chevy Powerglide transmission, when matched with the proper rear gear, is the quickest and most consistent of all existing transmission designs. ATI Performance adapter kits allow Ford, Chrysler, and import owners to also benefit from GM trannys by eliminating the hours of expensive modifications necessary to mate GM transmissions with non-GM engines. Each of these kits includes an ATI adapter plate, a crank adapter, a flexplate, and all necessary mounting hardware.

ATI Severe-Duty Super Starters

ATI severe-duty super starters pack a lot of power into a compact package--a hefty 3.0 hp, in fact. That's enough to crank over just about anything, and they only weigh about 12 lbs. These starters feature full ball-bearing or needle-bearing construction that's little affected by heat or cold, and most are "clockable" for multiple choices of solenoid positioning.
