Coil Over Spring Hardware for BMW E9 (1969-1974) 2800CS

Clear BMW chassis
Coil over suspensions consist of a spring mounted on the strut or shock body. The springs sit or are located by seats on the bottom and hats on the top. This is a similar arrangement as a stock strut but coil overs use a smaller diameter spring and the strut body is usually threaded for height adjustment. The top of a strut can also vary by manufacturer with the uppermost shock stem being manufactured in different ways that require special hardware. Our selection of spring seats, lock rings, and top hats has all been designed for use on various BMW coil over suspensions. Here you can find replacement parts for existing coil over kits and other spring hardware to complete your setup.

This plastic ring fits between the spring and spring seat and acts as a buffer, reducing noise, vibration, and wear on the spring seat. These are designed to take abuse as the spring moves on the seat and should be considered a consumable. These are plastic and isolate the spring from hitting the aluminum seat and making noise. This will also reduce wear on the spring seat. These are sized for the 60mm spring seat found on Bilstein, H&R, Moton, MCS, and other coil over kits. Priced per ring and such a simple but effective part you should never be without!

This aluminum spring seat fits between upper and lower 60mm springs to "join" them together. Typically you would have a main spring on top and a tender or helper spring on the bottom (or vice-versa). The spring joiner, or locator ring, fits between the springs with a retaining lip on the inside. We like this design better than an outside spring joiner because it's lighter and there's no material sitting on the outside where a tire might come in contact with it. These are priced per pair.
