Inner diameter measurements of 25 mm ensure proper alignment and fit within the rocker arm assembly. Constructed from sturdy steel, they resist wear and deformation even under high thermal and mechanical stress. Their accurate operation helps maintain optimal valve timing, which is essential for power delivery and emissions control. Properly functioning rocker arms contribute to smoother engine operation, reduced noise, and longer component life. Regular inspection and replacement prevent issues such as valve misalignment or uneven wear, which could lead to performance degradation. Ensuring the integrity of this part is fundamental for maintaining the overall health of the valve train.
