LA sleeves, American made since 1945. Sleeves are made from Moly2000 ductile iron. Pro cool wet sleeve helps
sustain proper cooling flow and perfect for turbo, nitrous and all motor applications. Made to maintain block integrity
with high horsepower engines over time. Brinell hardness of 265 (98.7 rockwell B) the material has great sleeve density. This provides consistent grain flow micro structure. The centrifugal process controls exact graphite and matrix distribution throughout the sleeves creating a wear and shock resistant sleeve for better ring seal and wear.
Continuous roundness and hardness offers a "no worry" sleeve for street use and all out racing applications.
