Which BMW models does this kit fit?

It is listed for 2002-2005 745i and 745Li, 2004-2005 645i, 2004-2006 760i, 2003-2008 760Li and 2006-2010 650i. Check your year, make and model and the interchangeable part numbers before ordering.

What is included in the kit?

One front lower thrust control arm for the rear position on the driver side (K620121) and one for the passenger side (K620122).

Is this a direct replacement for the factory arms?

ECCPP says the arms use an OE design for simple installation. Have a shop confirm the part numbers match your car's original arms.

Should I replace both sides at once?

Yes. Worn thrust arms usually age together, and replacing both keeps the front suspension balanced and saves a second alignment.

Do I need an alignment after installing these?

Yes. Replacing front suspension arms changes geometry, so a professional alignment afterward is standard practice.

Our take on the ECCPP Control Arm Kit

This is a pair of front lower thrust control arms for the rear position of the front suspension on several BMW 6 and 7 Series models from 2002 to 2010. The kit covers driver and passenger sides (K620121 and K620122) and is built to OE geometry, so it bolts in place of the original arms. It suits owners of high-mileage 645i, 650i, 745i, 745Li, 760i and 760Li cars chasing clunks, vague steering or uneven tire wear without paying dealer parts prices. Aftermarket arms like these are a value alternative to OEM, but fitment is model- and year-specific, so confirm your application before ordering.
