Details
Purpose-built for late model circle track and road-race applications, this fully assembled Andrews transmission ships ready to install with a proven close-ratio stack: 2.320 / 1.667 / 1.380 (with 4th direct 1.00:1). The 23" setback layout aids rear weight percentage and drives off the corner, while the carbon cover trims mass and helps stabilize temperatures over long green-flag runs.
Key Features
- Race-ready assembly-no parts hunting; install, fill, and go
- Close-ratio gearset for tighter RPM drops and stronger mid-range pull
- 23" setback configuration for improved chassis balance and CG placement
- Lightweight carbon cover for rigidity and heat management
- Precision-ground gears and dogs for fast, positive, clutchless shifts
- Modular construction for quick service and ratio changes
- Engineered for high-RPM, high-load competition environments

- 2nd Gear: 1.667:1
