Product Details

The Cometic C5683 is a precision-engineered 2-piece rear main seal designed specifically for Chrysler LA-series small block engines, including 273, 318, and 340 cubic inch displacements. This seal provides critical protection against oil leaks at the rear of the crankshaft where it meets the flywheel or flexplate.

Key Features:

  • Designed for Chrysler 273, 318, and 340 LA small block engines
  • 2-piece rope-style seal construction for proper sealing on vintage engine designs
  • Manufactured by Cometic using high-quality materials for durability and oil resistance
  • Direct replacement for worn or leaking factory rear main seals
  • Essential for engine rebuilds and restoration projects

This rear main seal is a critical component during engine assembly or when addressing oil leaks from the rear of the crankshaft. The 2-piece design is engineered to match the original specifications of LA-series Mopar small blocks, ensuring proper fit and seal integrity.

Your order is come in time, I appreciate your rapid response thank you

excellent customer service

So far, so good!

Ordered A K&N Filter For My Bike. The Price Was The Cheapest On The Web. It Shipped Right Away. Very Happy

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Cheap prices, great quality, and fast delivery. Autoplicity will continue to receive my patronage.

Easy and fast. Order arrived very fast. Thanks.
