RD™ and XL Technology Features

The Right Chassis Solution For Every Need
  • It's a fact of life - some vehicles work harder than others. That's why Dorman offers three lines of chassis parts designed for specific uses and situations, so you know you're getting the ideal replacement.

  • Dorman's chassis parts are designed for a direct fit and long service life. From control arms to bushings, sway bars, tie rods, and ball joints, chassis parts include premium features like sealed bearings, high-performance lubricants, corrosion-resistant finishes and new hardware.
Premium Chassis featuring XL Technology - Extended Life Chassis Parts
  • For drivers who want their vehicle to handle like new again, the line of Premium ball joints, tie rod ends, stabilizer links, pitman arms and idler arms with XL technology meets and goes beyond the quality of original manufacturer components.

  • Premium chassis products with XL Technology feature ArmourGrade™ studs, an advanced low-friction polymer socket, and highly polished EverSmooth™ ball surfaces for precise handling. Premium I.C.E.™ grease in a sealed housing ensures an extended maintenance-free service life while exclusive WeatherShield™ coating offers 5-10 times the corrosion resistance of OE finishes.

XL Technology Advantages

  • ArmourGrade™ Studs - A premium coated and hardened alloy deliver maximum resistance to both stud fatigue and corrosion, promoting vehicle safety. Studs are induction hardened when OE is required.

  • EverSmooth™ Ball Finish - A smoother ball surface means, less wear and increased durability for polymer-bearing sockets, when OE is specified.

  • UltraFlow™ Normalized Forged Housing - Normalized forging ensures the material has a small and uniform grain size of maximum durability, strength, and performance.

  • I.C.E.™ Grease - Premium I.C.E.™ (Intelligent Chassis Engineered) grease is an OE-approved formulation that ensures maximum performance even in extreme temperatures.

  • WeatherShield™ Coating - Exceeding OE standards, WeatherShield™ coating achieves 5 to 10 times the corrosion resistance as compared to other aftermarket coatings.
Premium RD™ - Rugged Design Chassis
  • For vehicles that operate under heavier loads and more severe duty, Premium RD ball joints utilize the same ArmourGrade™ studs and EverSmooth™ balls but feature a metal-on-metal design with larger bearing surfaces for increased load capacity and a greasable socket to ensure a long service life in all conditions.

Premium RD™ Advantages

  • ArmourGrade™ Studs - A premium coated and hardened alloy delivers maximum resistance to both stud fatigue and corrosion, promoting vehicle safety. Studs are induction hardened when OE required.

  • Larger High-Polish Ball - A larger ball surface distributes the load over a wider area, increasing durability and longevity under severe conditions.

  • IntegraFit™ Integrated Bearing Design - An exclusive premium hardening process allows us to eliminate the separate bearing and use a larger premium ball.

  • I.C.E.™ Grease - Premium I.C.E.™ (Intelligent Chassis Engineered) grease is an OE-approved formulation that ensures maximum performance even in extreme temperatures.

  • WeatherShield™ Coating - Exceeding OE standards, WeatherShield™ coating achieves 5 to 10 times the corrosion resistance as compared to other aftermarket coatings.
