Gears
& Gear Sets
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 1.58, 1.68, 1.76, 1.90, 1.94, 1.98, 2.08, 2.18 Vasco gear sets. All of ATI’s gears are produced in-house, from computermachined blanks to finished, shaped or hobbed gears 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. These Specialty Ratio gear sets are for SB cars only, lightweight cars such as dragsters, or low torque, high RPM combination cars. 283, 327, mild 350 CI motors and lightweight combinations usually fair very well with these ratios. ATI limits HP to 650 as a max with a lightweight car. Stock, Super Stock, Comp, and Bracket Dragsters are all viable applications.
Helical & Straight Cut Super Vasco Set Gears
- All 8 gears are new - long and short pinions, sun & flange gear
- No factory gears are used
- Each gear made of high quality Vasco steel
- Recommended for engines with a stroke of 3.5” or less
- Super strong lightweight ring gears in steel or aluminum

ring gear to the reverse pressure plate is totally
eliminated

quality of work warranty.
