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 and cool the bearings and ring & pinion gears. Additional features include a magnetic drain plug for catching ferrous metal particles, MIL-Spec (MIL-A-8625) black anodized finish, 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 Provide Additional Support to Bearing Caps
  • Magnetic Drain Plug for Easy Servicing
  • A356.0-T6 Aluminum Construction
  • Additional .5-quart Fluid Capacity
  • MIL-Spec Black Anodized Finish
  • Over 65 Years of B&M Quality
  • Lifetime Limited Warranty
  • Machined B&M Logo

Great value and Perfect Fit
This little oil filter wrench fit my BMW M340i perfectly and made the job a breeze. It locked onto the cap snugly, with no slipping or wobbling, and let me remove and reinstall with confidence. The material feels sturdy for the price and if you use the proper torque instead of cranking down on the housing, it should last a long time. Highly recommend for DIY oil changes.

Perfect on 1999 Volvo v90 XC AWD
I had looked everywhere for an oil filter wrench that would fit the cartridge filter on this1999 Volvo v90 XC AWD. Nothing local worked and then there was the issue where the recommended filter wrench slipped. When I was ordering the 86.6mm wrench, I looked at the pictures and noticed it said if I had a specific type of marking on the housing then I would need this 86.4mm wrench instead. Thanks to that bit of info I can now replace the filter. Works 100% like a charm and filter was easy to remove with a standard ratchet. Wrench seems well made and the price was perfect, especially compared to some of the others that are $35+. Very satisfied with this purchase.

It's simply works
Liquid Molly engine flush simply works.. Put it F 150 and eco boost with the chain rattle. Followed the instructions. A week later they rattling stopped. Scene clean all the sludge out.
