Allstar Performance small block rear main seal adapters can be used to convert 1986 and later blocks with a one-piece rear main seal to accept an older-style, 2-piece seal crankshaft. These adapters are essential when installing an early-style (1985 and earlier) crankshaft into 1986 and later blocks. These rear main seal adapters are available in different applications and can be used with a one-piece or 2-piece oil pan, depending on your application. They are made from billet aluminum and include hardware.

High Quality

Summit RacingSummit Racing Verified Purchase

While the adapter itself is high quality and works as advertised, the installation tool is way to expensive. I see no reason it needs to be made out of aluminum. Why couldn't it be made from plastic?? I elected not to use it. I simply installed the adapter onto the crankshaft letting the seal center itself. Then I CAREFULLY slid the adapter onto the block and bolted in down. more
