Gears & Gear Sets

Gear Sets | Shorty Gears | 3-Speed Low Gear Sets | Reverse Ring Gears

For Stock, Super Stock, Comp Eliminator and Circle Track only!
ATI stocks the widest selection of Powerglide Low Gears in the industry. These gears are based on the lightweight OEM 6 cylinder planetaries. Gear ratios include 1.68, 1.76, 1.90, 1.94, 1.98, 2.08, 2.18 9310 gear sets. All of ATI’s gears are produced in-house, from computer-machined blank to finished, shaped or hobbed gear using microprocessor-controlled equipment. The tools we use to cut our gears are coated by a Titanium Nitride process that improves tool hardness and allows the tool to remain in "like new" condition. This results in a premium finish on all gears and allows us to hold extremely close tolerances on pitch diameters and helix angles, assuring you the highest quality possible. OEM carrier gear sets carry a 90 day quality of work warranty.

Helical Cut Gears
• All 8 gears are new: Long & short
pinions, sun gear & flange gear
• No factory gears are used
• Each gear made high quality steel with a
tensile strength of 295,000 psi
• Recommended for engines with a
stroke of 3.5"  or less
 

Straight Cut Super Set Gears
• All 8 gears are new
• Super strong lightweight ring gear
• All thrust loading in the Powerglide from
the reverse ring gear to the reverse
pressure plate is totally eliminated
• Eliminates power loss from friction
 
• Thoroughly tested to reduce ET and reaction times
• Available in all popular ratios
