I have used hundreds of these seals in my high end Pontiac engine builds with success.
These rear main seals are made from top-quality Viton® material known for its excellent heat and chemical resistance.
Now owners of Pontiac V-8’s can enjoy the ease of installation and reduced friction of a Viton® rubber rear main seal.
These seals are not a retrofit from some other engine, but designed from a clean slate using state of the art technology and the best materials.
Beware of cheaper seals!
seals come with detailed instructions.
