The Enginetech R40638-040 Engine Cast Iron Piston Ring Complete Set is designed to restore performance and reliability to a range of classic Pontiac engines. Crafted with precision, this set includes all necessary rings to ensure proper sealing, compression, and oil control for optimal engine operation. Built from durable cast iron, these rings are engineered to withstand high temperatures and pressures typical of engine use, providing long-lasting performance and dependability.

Each ring features consistent end gaps following SAE guidelines, ensuring proper fitment and function. The top and second compression rings are both 5/64 inch thick, offering excellent sealing capabilities for high compression ratios. The oil ring, measuring 3/16 inch in thickness, effectively scrapes excess oil from the cylinder walls, maintaining clean combustion and reducing oil consumption. The rings are designed with an outside diameter of 4.063 inches, ensuring compatibility with select Pontiac engines from the late 1950s to the mid-1960s.

Engine rebuilders and enthusiasts appreciate the quality and precision of Enginetech parts, which are engineered specifically for engine rebuilding projects. This complete set simplifies the assembly process, providing all the rings needed to restore compression and oil control to engines such as the Pontiac Tempest, Bonneville, and Catalina from 1959 to 1966. Whether you're restoring a vintage vehicle or performing a rebuild, the R40638-040 set offers a reliable solution to improve engine performance and longevity, backed by Enginetech’s commitment to quality and customer service.
