Overview:

Our engineers designed the line of Hi-Tek differential covers to not only look good but address a number of weaknesses of the factory stamped steel covers. First, they started by constructing the covers of thick A356.0-T6 aluminum, which dissipates heat much faster than the factory steel unit keeping the fluid temperature lower under high-stress loads vs. a steel cover. Then for added durability, we added a reinforced center bar for extra strength along with load bolts to help prevent bearing cap deflection under severe loads. The internal shape of the cover retains the smooth round back internally to help keep the fluid flow going over the ring gear to properly lubricate the gears and bearings. Additional features include a magnetic drain plug for catching ferrous metal particles, machined B&M logo and all necessary hardware and easy to follow detailed instructions for a quick and simple installation you can do at home. Note: Gasket not included.

Features:

  • Load Bolts for Additional Support for Bearing Caps
  • Magnetic Drain Plug for Easy Servicing
  • Additional .50-quart Fluid Capacity
  • A356.0-T6 Aluminum Construction
  • Over 65 Years of B&M Quality
  • Lifetime Limited Warranty
  • Machined B&M Logo

Fun but not for rough play.
Color: Orange
The ball contented our “golden” Jaxson for about 15 minutes. He then thought it was a regular ball and it’s just a little delicate for a big dog. I just wrote it off as a loss. Great idea but should be more durable.

My 50 pound goldendoodle absolutely loves this ball. It keeps a charge for a long time. It turns off When it’s not being used and we play with it every day.!

Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.

My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.
