Pontiac rear main seal kit TIP-RM325 with Permatex Ultra Black RTV Silicone

This is our 3.25″ Tin Indian Performance Pontiac Viton® rear main seal kit. The kit includes one 3.25″ rear main seal and a 3.35 oz tube of Permatex Ultra Black sealer. This is the same sealer that we use on EVERY ONE of our engine builds and rear main installations! The 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.
