IND is proud to announce the new release of the Macht Schnell Underdrive Pulleys! The S85 kits are in stock and ready to ship.

Machined from 6061-T6 aerospace aluminum, Macht Schnell Performance Underdrive Pulleys are strong as well as lightweight to limit parasitic drag from the accessories within a moderate level for maximum performance on or off the track. After machining and engraving, pulleys are then T3 hard anodized for additional strength, anti-corrosion & wear resistance.

Macht Schnell's DualDrive design replaces the Crank Accessory & Power Steering Pulleys, resulting in a 18-20 HP and 16-20ft. lbs TQ gain from reduction in power required to turn accessories and an increase in accessories lifespan due to lower speed. All factory harmonics/balancing are undisturbed.

Macht Schnell Performance Underdrive Pulleys have no negative effect on accessory operation and come fully equipped with new belts.






Performance Underdrive Pulleys Features:
- DualDrive design allows maximum performance, with minor affect on accessory speed
- Proper cooling temperatures are retained at proper levels on or off the track
- Maintains proper alternator speed, allowing sustained levels to sensitive control modules
- Machined from 6061-T6 aerospace aluminum
- T3 Hard-Anodized for maximum strength and corrosion/wear resistance
- No affects to crankshaft dampening or harmonics
- Includes heavy duty fasteners
- Simple bolt-on installation
