Custom Springs

We make replacement springs engineered specifically for Mercedes-Benz, covering models from 1926 through 1992. All of them are manufactured exclusively for John R. Olson, Inc.

Progressive rate springs

For older cars, 1926 to 1989. They adapt to how you are driving: comfortable when you are taking it easy, then up to 30% firmer under hard braking and cornering, which cuts nose dive and steadies the car.

Sport springs

For anyone who enjoys a winding road. Twenty to thirty per cent firmer than factory, with noticeably less body lean and no real penalty over a long distance. Finished in semi-gloss Smoke Black.

Custom springs

Built to your car and your driving — specifications matched to a particular setup, whether that is everyday use or something more competitive.

Why these rather than factory

Mercedes-Benz set their suspensions up for average conditions. Ours are built by enthusiasts, for enthusiasts, on decades of research and hands-on work — a smoother ride, better cornering, or steadier braking, depending on what you are after.

All final orders are taken by telephone. Call (612) 377-0155 and we will work out the right set for your car.
