Excellent product.

April 21, 2014
Product was as advertised. Required a good amount of cleaning to before assembly but that is expected due to the amount of anti-rust agent on the part, everything and anything clings to it during shipment. Speedway should note that these lower gears require shorter ring gear bolts than most other ring gear ratio's. Lucky I carry inventory and it did not interrupt the installation process.
Yes, I recommend this product.

When you order the ring and pinion it will come with just the ring gear and pinion gear. We offer a shim kit 54584751 and also a solid pinion bearing spacer kit 9190920. The solid pinion bearing spacer would take the place of a crush sleeve. We do not carry a crush sleeve. Hope this helps you out.

Lubrication Engineers SAE 140 Weight Gear Oil, 1 Gallon
(Part #91044140)
                        

Whether you're running a stock flattie and rearend or hopped-up overhead and quick change, you need to run a good gear lube. Remember that your rearend was designed fifty plus years ago and needs all the help it can get. The biggest improvement you can give it is a lubricant that will allow the gears to survive the highway speeds that cars see today. L.E. gear oil is what we use in our 350 mph streamliner, that uses a V-8 quick change, without failure. The "red stuff" provides superior lubrication for long gear life. You can't win if you don't finish. We suggest 90 weight for the street and 140 weight for extreme uses.

  • Formulated using blends of high quality paraffinic and synthetic base fluids
  • Contains a highly shear stable tackiness
  • Unique blend of base fluids and thermally stable EP additives
  • Separates readily from water
  • Contains non-silicone defoaming additives
