Ventilated Follower
Detroit Diesel

This ventilated spring is engineered to maintain proper valve timing and operation by exerting consistent pressure on the valve components. Its 52.30 mm free length combined with a 2.60 mm wire diameter ensures durability under dynamic load conditions. The spring's inner diameter of 8.90 mm and outer diameter of 14.10 mm are optimized for compatibility with valve stems and guides, facilitating smooth movement and preventing valve float. The steel construction offers resilience against fatigue, corrosion, and high temperatures, which are prevalent in heavy-duty engine environments. Its design ensures reliable contact and consistent tension, critical for engine performance and emission control. Proper installation and periodic inspection of this spring help sustain engine efficiency and prevent misfires or valve damage.
