The RK series is a more value driven part. Because there are so many different vehicles both foreign and domestic, Moog has introduced the R-Series arms to provide replacements for a wide range of vehicles. The RK arms have OE fit and form geometry alignment, with pre-installed OE style bushings and most include the ball joints. However these ball joints are not serviceable like the CK arms. All of the R Series arms have Moog validated construction and design, providing a less expensive alternative.
Features- Most CK and K control arms include ball joints that are powder coated metal with gusher bearings giving them a long life
- These ball joints are serviceable and have grease fittings
- The CK and K arms also have problem solver bushings and a precise fit and form for easy installation
