Piston Ring Set 4.030 1.5 1.5 4.0mm

The Piston Ring Set 4.030 1.5 1.5 4.0mm by HASTINGS is a precision-engineered component designed for high-performance engine rebuilds and modifications. This ring set is ideal for engine builders, mechanics, and automotive enthusiasts who are increasing engine displacement through boring operations or installing forged piston kits in performance applications.

When an engine block is bored to 4.030 inches, standard ring sets are no longer suitable. This matched set features a top ring thickness of 1.5mm, a second ring thickness of 1.5mm, and a 4.0mm oil ring thickness, providing an optimal balance between sealing efficiency and reduced friction. HASTINGS rings are crafted from premium iron alloy materials, ensuring durability and consistent performance across various engine conditions.

This piston ring set is essential for anyone boring a small-block or big-block engine to 4.030 inches, ensuring proper sealing and oil control. It is particularly beneficial for those building street or competition engines, as it helps maintain cylinder pressure and manage blow-by gases effectively.
