When you need the most control and slow-speed precision, choose the Speed Reduction Upgrade for your Ultrafeed® Sewing Machine. This package is designed for Ultrafeed machines equipped with the WorkerB® Power Pack Motor System. The addition of the Monster® II Balance Wheel gears down the WorkerB motor, reducing your sewing speed by half compared to the standard WorkerB® Balance Wheel. Accept no imitations. The Sailrite Monster II Balance Wheel is the original.

This upgrade is ideal for leatherworkers, hobby sewers and beginners who want the comfort and ease of slow, controlled sewing and anyone who prefers to sew at a slow, steady pace. The balance wheel also includes a hand crank for those who wish to sew manually without electricity, making this package a great choice for on-the-go sewing and repair jobs.

Note: This package is intended for Ultrafeed machines in the current Industrial Carrying Case as it includes a compatible kickstand; otherwise, please order the Monster II Balance Wheel separately (#604U). If you have an older machine without the Posi-Pin® Safety Shear, please order #604U as it includes locking set screws to "lock out" the older style friction clutch, which is prone to slipping.

Speed Reduction Package Includes:

• Monster® II Balance Wheel
• Cogged Timing Belt
• Kickstand for Ultrafeed® Industrial Carrying Case
