The Shaftworks difference
Your dampers, valved for your car
Born from a love of speed and precision, we custom-valve high-end suspension to put passionate racers on the podium. Tell us about your car, weight, tires, and discipline — we'll build the curve to match and verify it on the dyno before it ships.
“Really great suspension at a good price. Outstanding customer service as well — I always get good answers when I have questions. The Bilanx suspension makes the car so predictable and well balanced with a lot of grip. I very highly recommend Shaftworks!”
