• Phosphate Finish: Extremely durable. Double coated. Threads coated as well. Rugged look.
• Grade 8 - Class 10.9 Hardware: Superior tensile strength.
• Tension Nut: Very strong hold in most applications.
• 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.
• 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.
• 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.
• 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.
• 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.
• Custom Features: Upgraded design secures ball joint to control arm via a robust nut and forged flange instead of OE C-clip design.
