This new check strap fits all 123 sedans and wagons from 1977 to 1985, including the 280E, 240D, 300D, and 300TD. It will not fit on 300CD or 280CE coupe models. This will fit the right and left sides, as well as the front or rear door. If either of your doors is not staying open, creaking, or closing with difficulty, you need to replace the check strap before it breaks and damages your door. Now we included longer bolts than the original to make installation easier and blue thread locker to make sure they won't back out. Watch the YouTube video below for more details.
Product Details
Failure of the front door check strap is almost always caused by rainwater washing away the grease and drying out the ball mechanism, which eventually leads to failure. We now provide a cover that you can assemble on the check strap before installation. There is only a little grease on this new strap, but we recommend adding a couple of generous globs of synthetic grease or wheel bearing grease before installation.
This is what happens when the lubrication dries up!

INSTALLING IN THE REAR W123 DOORS: READ CAREFULLY: Since Mercedes no longer makes rear door checks, we can only obtain aftermarket front door check straps and modify them for use in the rear door. In some years, these may not fit "perfectly". It has to do with the hole alignment for the attachment bolts (primarily on the door panel). You may have to take a round file and enlarge the hole slightly. This check strap also has two detents as opposed to one on the original. That can actually be an advantage. The check strap will work just fine. PLEASE DO NOT ORDER UNLESS YOU UNDERSTAND THIS.....
New cover supplied ( you attach - instrucitons included).
