  • Uninterrupted Wheel Speed Signal
    Uninterrupted Wheel Speed Signal
    A molded, thicker and abrasion-resistant cord guards against perforation and contaminants at both the sensor and plug ends to ensure a faultless signal for ABS, TCS and other vehicle safety systems. The sensors match to the original for type and output characteristics, meaning no interruption in this service.
  • Repel-TEK Anti-Corrosion
    Repel-TEK Anti-Corrosion
    Repel-TEK™ anti-corrosion coating is applied to every surface, including studs and hardware, to prevent buildup and contaminant intrusion. This also makes removing associated components easier, like swapping wheels, replacing a CV shaft or a brake rotor.
  • Everything in the Box for a Complete Job

    Additional material is added to the part to improve body stiffness and strength.
  • Bi-Metallic Control Arms
    Bi-Metallic Control Arms
    Exclusive patented (US no. 8757648) technology which allows for a ball joint featuring sintered metal bearings to be threaded into an unitized aluminum control arm.
  • Bushing Radial Knurling
    Bushing Radial Knurling
    Bushing design with knurling on inner sleeve that assists to secure the bushing to the frame.
  • Greaseable Ball Joints
    Greaseable Ball Joints
    Ball Joint is serviceable allowing the user to continue to grease the ball joint improving the service life of the ball joint.
  • Sintered Metal Bearings
    Sintered Metal Bearings
    Bearings made of a durable sintered powder metal that leads to a longer lasting part.
  • Patented Snap-In Bearing
    Patented Snap-In Bearing
    Oversized sintered metal bearing with large contact area is engineered to accommodate challenges of a worn knuckle.
  • Self-Sealing Grease Relief
    Self-Sealing Grease Relief
    Grease relief that acts like a one-way valve allowing excess grease to flow out of the boot while preventing contaminants entering the boot.
  • REPEL-TEK Coatings
    REPEL-TEK Coatings
    Corrosion resistant coatings that prevent the formation of rust for a longer part service life.
  • Integriboot
    Boot is mechanically locked in place by the housing lamination preventing contaminants from entering the boot.
  • Optimized Compression Control (OCC) Design
    Optimized Compression Control (OCC) Design
    Designed to prevent over-compression of bushings during installation which extends the service life of the bushing.
  • Patented Stepped Bearings
    Patented Stepped Bearings
    Engineered bearings designed with a recess that prevent flattening of the Belleville spring washer which leads to an increased service life of the ball joint.
  • Anti-Corrosion Coatings
    Anti-Corrosion Coatings
    Corrosion resistant coatings that prevent the formation of rust for a longer part service life.
  • Circlip
    Secure the ball joint with the circlip included to provide supplementary retention for the ball joint housing, locking it into place.
  • Patented Directional Bearing
    Patented Directional Bearing
    Allows for proper implementation of upper bearing on ball joints with larger swing angle in one direction. Addition of upper bearing provides additional contact area and greater pressure distribution for less wear.
