Built to handle the torque, load, and demands of GM’s Duramax-powered workhorses, the Apex Chassis Super HD Lower Ball Joint is engineered for maximum strength, precision, and reliability. Whether you’re hauling heavy, towing long, or working your Silverado or Sierra HD to the limit, this joint delivers the stability, control, and durability your diesel front end demands.

Each joint starts with a forged SAE 1045 solid steel housing for unmatched structural integrity and a hot-forged SAE 4140 Chromoly ball stud—polished and heat-treated for superior load-bearing strength. Apex’s military-grade acetal bearing, the same material used in U.S. military Hummer suspension components, ensures smooth articulation and long-term performance under the extreme loads of heavy-duty diesel applications.

Every component is CNC-machined for exact tolerances, induction heat-treated for consistent metallurgy, and E-coated for corrosion resistance. A compression-style CR rubber boot seals out contaminants and retains lubrication, while the angled pre-threaded zerk housing makes servicing quick and clean. With gull-wing grease grooves, pre-greased internals, and Grade 8 hardware, the Apex Super HD Ball Joint sets the standard for durability and serviceability in GM Duramax platforms.

HOUSING

  • SAE 1045 Solid Steel Forged Housing: This is unequivocally the best carbon alloy steel for this application.
  • Knurled Housings: The preferred design for aftermarket installations.
  • CNC Machined Housing: Make our parts and bearings dimensionally perfect, eliminating any die wear issues.

BALL STUDS

  • SAE 4140 hot forged Chromoly Ball Studs: For the strongest possible metallurgy.
  • Induction Heat Treated Ball Studs: Provides a very precise heat treatment to the exact depth and location we want it.
  • Polished Ball Studs: Are built like an anti-friction bearing with extremely precise tolerances.
  • Rolled Threads: Are made by pressing the shape of the threads into the ball stud instead of cutting. This strengthens the threads instead of weakening them and allows for easy movement of hardware. This ain't no Ikea furniture!
  • Step Threads: Allows for very easy movement of hardware on install and superior holding when torqued (installer choice).

BEARING DESIGN

  • Military Grade Acetal Bearing: The same bearing material spec'd by the US military for Hummer ball joints. This material is dimensionally stable (doesn't expand or contract with hot or cold, water or oil absorption), it can be polished smooth as steel, is anti-friction, doesn't wear itself out under load like metal on metal, and can take an absolute pounding.

BOOTS

  • CR Rubber Boots: The most durable material for undercar applications. Resistant to deterioration from road level ozone, oil/gas/engine fluids and extreme heat or cold.
  • Compression Boot

FINISH

  • E-Coating: Extremely durable electrochemical finishing process.

HARDWARE

  • Grade 8 - Class 10.9 Hardware: Superior tensile strength.
  • Castle Nut: Industry standard where high vibration loads occur.

LUBRICATION

  • Pre-threaded Zerk Housing: If you have ever installed a MOOG Ball Joint without a pre-threaded zerk fitting you will understand what a simple but great feature this is. Another installer fav.
  • Greaseable: Because it should be.
  • Pre-Greased: Just in case you forget, we have you covered.
  • Gull Winged Grease Grooves: Allows for improved lubrication disbursement around the ball stud.
  • Zerk Fittings: Included for every application.

Good Product
Size: 3 Panel-102'', Color: Beige
I got these dividers for outdoor use for some privacy from neighbors. They arrived quickly and were easy to set up. They look good, and though the legs don’t offer stability against any amount of wind—which I expected as it wasn’t advertised for outdoor use—all it took was placing a cinder block on the feet to hold it up right. Coverage is good, it’s easy to fold and move as needed, and it’s light weight. All in all a decent product. I will caution the purchase of “used like-new,” as both of the dividers I ordered were previously returned items, and one came missing a cap, instructions were not included, and the poles were all mixed up and not properly labeled. If I had not ordered a second divider (which did include the instructions) I would have had a much harder time figuring out which pieces were which and how to put them together.

So versatile! Perfect solution for dividing a room.
Size: 4 Panel-88'', Color: Grey, Size: 4 Panel-88'', Color: Grey
Perfect solution for my space. My office has to double as the hangout room for the kids and I wanted something that would block off my computer so it is left alone. This space allows me to close off my computer as much or as little as I want. It is lightweight yet has sturdy feet. This is important so that if it gets bumped it won’t topple over. The price was great and the build time wasn’t too bad! I would recommend two people for set up. I went with the grey panels and I think I’ll end up hanging some twinkle lights at some point. Great purchase!

4/5 Stars
Size: 4 Panel-88'', Color: Black
Very tall and easy to set up, the only thing I will say is that they do have large gaps in between, so you won't have 100% privacy unless you add a curtain in the back. Other than that, they are easy to fold, sturdy, and esy to assemble. The gaps are an easy fix so I would say they are worth it.

Great product and worth the money.
Size: 4 Panel-88'', Color: Black
Portable and stable. Perfect size and gives me the privacy I need when working from home. Stability is great as long as you place the stands correctly it won't wobble. I love it.

Attractive
Size: 4 Panel-88'', Color: Grey
The assembled product is just as described. The screens look great! I am using them to hide the cluttered shelving in my garage. The area now looks quite neat Something I must say, though, is that the assembly was extremely difficult. I had to use a silicone spray and some pounding to get the A and B poles to fit together. Also, it required a great deal of strength to stretch and hold the fabric panels so that the bars inserted in each hem lines up with the screws inserted in A/B poles. I strongly recommend having a partner to help with the assembly. while sc and screw into poles them once inserted intetchedtne end of each pole ( and B poles barely fit together. I used silicone spray on the end and then pounded them
