SpeedFactory Racing HD Timing Belt Tensioner Spring - B-Series

SpeedFactory's B-Series HD Timing Belt Tensioner Spring provides proper tension for high-performance engines, especially with stiff racing belts.

• The OEM spring is very weak and requires a much higher spring rate.
• Insufficient tension can lead to poor cam timing control and valve damage.
• Over-tightening with manual methods can cause belt and cam journal wear.
