ATI

ATI Performance Products has been at the forefront of race-winning drivetrain engineering since the 1980s, with over a dozen U.S. patents backing a catalog built for serious competition. From drag racing's top professional classes down to weekend street/strip builds, ATI components are trusted when reliability and power transfer are non-negotiable.Popular UpgradesThe ATI Super Damper is the gold standard in harmonic balancer technology, reducing crankshaft torsional vibration to protect engine components under high-RPM loads. The Superglide transmission series and Treemaster Converters are proven choices for automatic-equipped performance builds, while the Compu-Flow Valve Bodies add precision shift control. Flexplates, adapter kits, and internal transmission components round out the catalog for builders needing complete drivetrain solutions.Are ATI Super Dampers street legal?Yes. ATI Super Dampers are SFI-certified and designed for both street and strip use. They are a direct repla...

Crankshaft Dampers

Crankshaft Dampers

Crankshaft dampers, also called harmonic balancers, are the weighted pulley assembly at the front of the crankshaft that absorbs and dissipates torsional vibration created by combustion pulses. A failed or deteriorating damper allows crankshaft harmonics to build up, accelerating bearing wear and potentially causing catastrophic crankshaft damage in high-RPM or high-output engines.Popular UpgradesPerformance underdrive harmonic dampers that reduce parasitic accessory drive load are popular on naturally aspirated racing engines where every horsepower counts. SFI-rated dampers meeting the Society of Fire Integrity 18.1 standard are required equipment at most sanctioned drag racing events and are recommended for any high-RPM performance build. Replacement OEM-spec dampers restore factory harmonic control on high-mileage street vehicles where the rubber bond in the original damper has failed or the outer ring has begun to walk forward on the hub.How do I know if my crankshaft damper is ...

Crankshafts & Components

Crankshafts & Components

The crankshaft and its supporting components form the structural and mechanical core of every reciprocating internal combustion engine. Upgrading the crankshaft assembly with forged steel cranks, precision bearings, dampers, and timing components builds an engine bottom end capable of handling the power and RPM demands of a serious performance build.Popular UpgradesForged 4340 crankshaft sets paired with matching connecting rods, ARP main studs, and performance main bearings are the standard specification for any V8 performance build targeting 500 or more horsepower. Billet crankshafts for maximum-effort race applications provide the highest strength-to-weight ratio available when a forged crank's fatigue limit is a concern. Timing components including double-roller timing chains, billet steel gears, and cam phasers should be upgraded alongside any crankshaft swap to maintain proper valve timing under the increased loads of a performance build.What crankshaft components should be re...
