What is the Difference Between Moog R Series and CK Control Arms?

CK, K or RK? We here at Diverse Suspension Technologies get this question a whole lot. If you are putting parts on your vehicle, you want to know exactly what you are installing. It can be hard to do that with all of these letter designations. So here is all that you need to know to clear up the confusion.

Short Answer: R Series is a value-driven replacement part while the CK Series incorporates Moog's premium Problem Solver components for a better than OE upgrade.

CK (K): Moog Problem Solver

Starting with the CK and K. Whether you see a "K" designation or a "CK" designation, you are getting the same part. The CK and K are Moogs Premium line of control arms. Utilizing their "problem solver" technology, these control arms address common factory design issues providing a better than the original replacement for your vehicle. Most CK and K control arms include ball joints that are powder coated metal with gusher bearings giving them a long life. Many of 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.

RK: Moog R Series

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.

Type and Warranty

Each line of control arms has Forged Steel, Stamped Steel, or Forged Aluminium arms to provide the best style for your specific vehicle. The Premium CK line has a limited lifetime warranty, and the RK has a 3 year warranty that are both handled through our awesome customer service team at DST. Whether you are looking for a "light on the wallet" OE replacement, or a "premium" control arm upgrade, Moog control arms are a great choice for your vehicle.

starstarstarstarstar_border" Good quality but poor fit "

I have always trusted Moog parts and this seems to be really good quality. However, the fit isnt that great. Maybe Im doing something wrong but this is 1/8" shorter than the OEM I took off and as such it change my camber quite a bit. It is threaded as if it can be adjusted but I mounted it in a vice and used very large wrenches and could not turn it no matter how hard I tried. I believe they must have crimped it in place and so it wont adjust. After installing it the camber is now at the max allowed so I suppose its still good? However, I would have liked to have been able to adjust the camber back to where it started. Because of this link being short and not adjustable it also required me to adjust the tow after installation. So, if you use this link plan on having to do an alignment afterwards. Editors Note: After any steering or suspension part is replaced an alignment has to be done. If your vehicle is high mileage and replacing one part the alignment could be at the end of the adjustment.
