Apex Chassis Heavy Duty Front Upper Ball Joint, Knurled.
Note:
- Knurled is designed for vehicles with aluminum knuckles that have undergone 2 to 3 ball joint replacements.
What It Fits:
- Jeep Wrangler JL (2018-2026) 4WD
- Jeep Gladiator JT (2019-2026) 4WD
The Special Sauce:
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: Built like an anti-friction bearing with extremely precise tolerances.
- Rolled Threads: 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
- Bronze Bearing Design: Our newest improvement in bearing design. Combines our perfectly polished ball studs, encased in a solid steel forged housing, lined with a highly durable, low friction bronze bearing.
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.
- Internal Seal Boot: The boot is coined onto the ball joint, for superior sealing against contaminants.
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.

Border Collie Approved: Easy to Clean, Durable, and Great Bounce
Size: Medium (2.5"), Style: Fetch Pack 2
These are the best balls out there for dogs. These fit great in the chuck-it ball launcher, which we need to wear out my border collie. They fit her mouth properly and, most importantly, do not absorb all the spit or water after a good rain. They are quick to clean off and have good weight so you can let them fly! Furthermore, they bounce well, which is perfect for my dog that likes to catch them on a bounce. The ball is a strong rubber, so should not be easy to chew up. I've used these for years, and the only time I've had to replace them is when one gets lost in the hay field. I highly suggest these as replacements for the common tennis balls.

Treats and plenty of ball throwing with these doggie toy
Size: Medium (2.5"), Style: Fetch Pack 1
I have actually purchased these twice already. I love the one that glows in the dark but it still got lost in my yard lol. My dog is a big breed half pitt/Labrador so she did chew through one of them already. I play ball with her every single day but I DO have to take them away from her because she will destroy them. They are great to add in treats as well, that was one of the my favorite things about them as well. They do last just if you have an over zealous chewer do not let them keep them for long periods of time. They are a good value for the price. Buy them your dog will love it!

My Female GSD loves
Size: Medium (2.5"), Style: Fetch Pack 1, Size: Medium (2.5"), Style: Fetch Pack 1
Shasta is my smallest. Six in December (2025) along with her brother. She’s 100 lbs and outside, completely ball driven see last picture. Don’t let the size (2.5”) of these Chuck-It balls deter you. If your larger Breed dog has any orthopedic issues, has already torn their ACL etc, one has arthritis but wants to play. This size is perfect!
Shazzy was born with several ortho issues. I don’t throw balls distance but right to her. This size and lighter weight assure even when Shazzy is spazzy w excitement, she’ll catch the ball mid air.
The green balls are softer, and glow in the dark. In summer we can play well past dusk and I can see them!
Her personality shows in the pictures. Playing ball is part of her. These balls are just perfect for her situation. Somehow they disappear, she loves making baskets, puts them in my tractor bucket, or my gardening bucket..then get put in burn pile, trash etc. I keep replacing them because she’d look day and night if we actually ran out!! 🙏✝️👍🏼👍🏼

SHORT-game Ball Launcher … love it!
Yes, this is a smaller ball launcher … It is for her SHORT Game! Love it AND the squeaky baseball that came with it is A-HIT!! Our black golden doodle, Josie, carried that around for hours … batting it around, jumping on it, resting with it right-next-to-her. For your pup’s LONG game, purchase the longer launcher. GAME-on!
