SSP-G Performance QMB139 Torque Spring Base
- Overall Height: 30mm
SSP-G Performance Torque Spring Base for 50cc QMB139 4-stroke engines and engine based vehicles.
The QMB139 Torque Spring Base will allow for smoother torque spring action through the use of roller bearings. This allows the spring to pivot and turn free rather than binding up.
