Review on 🔧 MOOG RK620054 Control Arm and Ball Joint Assembly: Durable and Reliable Suspension Component by Timothy Johnson

Most people don't realize that Moog makes 2 or 3 different levels of the same part. The RK series is the cheaper of the 3, has no oilers and ball joints are not interchangeable but still better than most discount car dealership brands. "K" or "CK" are higher or medium quality and have higher quality components and grease fittings with higher quality replacement ball joints and bushings. Then they have their off-road or extreme conditions that are harder to find and expensive. "RK" have a limited three year warranty and "K" and "CK" have a limited lifetime warranty. These RKs are of decent quality for everyday driving. If you drive off-road from time to time, it is best to use "CK” or "K”.
