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, 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.

Features:

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

Great chair keeps you feeling cool!
I love the mesh areas - it keeps you feeling cool. I love the high back and neck area (it’s adjustable) the seat tilts back and allows you to relax (for me it’s a good back stretch ) I recommend this chair for any office use!

Sturdy and Comfortable
I’m really impressed with this ergonomic office chair. Assembly was incredibly easy I had it put together much faster than I expected, and everything fit together perfectly without any frustration. The teal green color is beautiful and one of my absolute favorites; it adds such a nice pop to my workspace. As a heavier person, I’m always cautious about weight capacity, but this chair feels genuinely solid and supportive. No wobbling, no sinking just sturdy, reliable construction. The seat cushion is comfortable for long hours at the computer, and the back support has made a noticeable difference in reducing my back pain. I also appreciate how easy it is to clean. A quick wipe keeps it looking fresh, and the material doesn’t trap dust or pet hair. The wheels glide smoothly, making it easy to roll and turn without any effort. For the price, the quality and value are fantastic. This chair has definitely made my workdays more comfortable. I highly recommend it especially for anyone who’s heavier and hesitant about sturdiness.

Great chair — comfortable, sturdy, and surprisingly easy to assemble
The first thing that impressed me was how steady and solid it feels. It’s not wobbly or flimsy at all, and the base and wheels roll smoothly without feeling cheap. Once assembled, it feels like a chair that will last. Assembly was also easier than expected. The instructions were straightforward, and all the parts lined up well. My 12-year-old son helped assemble it and was able to do most of it himself with some effort. Comfort-wise, it’s excellent for everyday use. The mesh back is breathable, the seat feels supportive, and the tilt adjustment (90–125°) is a nice bonus when I want to lean back and relax. The 3D armrests are also a great touch and help with positioning for desk work. Overall Nice chair

Sturdy, comfortable and solid chair for focused-workers
Color: Onyx Black
I LOVE THIS CHAIR! I've had a manager's style leather chair for the past four years from one of the office supplies big box stores and the armrests began to wear off, so the need for a suitable replacement was needed. Immediately, I knew how badly my posture was in the former chair and the ergonomics of this chair are 100% comfortable. The lumbar support is a little difficult to adjust correctly and that would be my only item for the makers to improve in future iterations. Overall, I am impressed with the quality, ease of assembly and downright comfort of this chair. I enjoy the settings especially the one to lock-in the recline degree of the back halfway and the leg rest is durable and strong. This change was for the better and I'm way more energized to get through my digital workflows for hours at a time without any fatigue. The item is cheaper than when I bought it and that's an absolute steal and bargain with much value hopefully for years to enjoy.
