3" Tin Indian Performance Pontiac Viton® rear main seal.
TIP-RM300
These seals are specifically designed for
the traditional Pontiac block and they fit both stock and aftermarket
MR-1 Pontiac blocks. The seals are made of Viton® and are far superior
to the factory rope seal. They are the single most reliable way to
control oil in a Pontiac engine. This product is a direct replacement
for the conventional rope style seals in Pontiacs which are prone to
leak over time. Our seals are made and designed by Pontiac Engine
Builders and are the clear choice when you want the absolute best in oil
control when rebuilding your Pontiac engine. This is for 1 SEAL ONLY!
