Product Details

The Sierra 18-6406 is a GKN-style universal joint assembly designed as a direct replacement for Mercruiser sterndrive systems. This u-joint connects drive shaft rods whose axes are inclined at an angle to each other, transmitting rotary motion efficiently between components.

Key Features:

  • GKN new style design with external snap ring clips for secure installation
  • Direct replacement for Mercruiser OEM part numbers 865496A01 and 865493A01
  • Compatible with Alpha I Gen II sterndrives (serial number 0L949779 and up)
  • Fits Bravo sterndrives (serial number 0M111208 and up)
  • Suitable for Mercruiser Vazer applications
  • Precision-engineered for reliable performance in marine environments

This replacement u-joint assembly is an essential component for maintaining proper drive shaft operation in your Mercruiser sterndrive system. The external clip design provides easier installation and service compared to older internal clip styles.

You had the part's in which I was looking for The only hang up was trying to match all parts for the sizes that would fit together

Very easy to navigate and great pricing!

Smooth. Would do business again

Better price than going direct to the manufacturer.

Fantastic! Will definitely do business in future!

Good so far

thanks

Easy shopping, however the confirmation from the warehouse and then the shipment to my home, took a week. For an overall product purchase it's fine, but if you have your car broken and you are waiting for the part, the waiting time is terrible.

quick and easy

so far so good

Installed a 5th wheel hitch in a F150 with a 5 1/2' bed. Autoplicity had the Sidewinder hitch I needed to put the swivel under the camper insead of at the hitch,also at a lower price than competitors with extremly reasonable shipping $14.38. I Placed the order on a Friday and the item shipped the same day. Very happy with the product and fast shipping.

Great prices!!

Is the part in stock or on back order

Your website is very easy to use and I love the fact that I could pay through Amazon.
