Pontiac Rear Main seal

We are happy to introduce our new and improved 3" Viton ® Pontiac Rear Main Seals as well as our 3.25" Viton ® Pontiac Rear Mains seals.   Why the redesign you ask?  Most of the changes made to the seal were cosmetic - plain and simple!  Excess flash has been removed from the seals and other areas of the molding process "tightened up".    See below....

 Unlike other seals are seals made in the USA (not  some foreign country) AND we have such confidence in our product, we will never try to sell you a revamped rear main rope seal.  You won't EVER see us selling a rope seal, period!  Our seals are clearly labeled with TIN INDIAN PERFORMANCE  and both the RM300 and  the RM325 seals.  We are so confident in our seals that we put our company name right on them; not some other company name or no labeling at all. Our seals are color coded as well.  The purple seal is our 3" Viton ® Pontiac rear main seal and our black seal is our 3.25" Viton ® Pontiac rear main seal.  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.  We are consistently lookinf to improve and deliver the best quality possible in our gaskets and seals.
