Heavy Duty Ball Joint Kit Fits: Polaris 14-20 Apex Chassis

At APEX we like to say our quality is not consistent, it's constantly evolving.

We rely entirely on engineering, in-house and off-road testing as well as customer feedback to decide on the best design and materials to choose. Our customers are often astounded when their suggested modifications are introduced in our next production.

We are also not tied to any one dogma of design and construction.

The bearing designs that we use are individually tailored to each part based on application and load. Our ball joints are the go to ball joint for many podium finishers in both NORRA 1000 style and Ultra 4 style racing.
The Special Sauce:

• Housing
  • SAE 1045 Solid Steel Forged Housing: This is unequivocally the best carbon alloy steel for this application.
  • Knurled Housings: No.
  • 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.
• Bearing Design
  • Rugged Metal to Metal 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
  • Accordion Boot: ideal for high-articulation components, more flexibility means longer life.
• Finish
  • Phosphate Finish: Extremely durable. Double coated. Threads coated as well. Rugged look.
• Hardware
  • Grade 8 - Class 10.9 Hardware: Superior tensile strength.
  • Tension Nut: Very strong hold in most applications.
• 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.
• Special Features
  • Custom Features: Upgraded design secures ball joint to control arm via a robust nut and forged flange instead of OE C-clip design.
