Vibration Reducers Noise, vibration, and harshness are at the top of the list of concerns to all automotive enthusiasts. With the more frequent use of rack and pinions and low profile performance tires, there are more road vibrations transmitted to the steering wheel than in the past. Using a Borgeson vibration reducer results in an immediate change in the steering feel and as an added benefit, this reduction in vibration has been shown to increase the overall life of the steering components. Vibration Reducer / Universal Joint Combination The Vibration Reducer / Universal joint Combination is available with a 9/16”-26, 5/8”-36, 3/4”-30, 3/4”-36, or 3/4”DD vibration reducer end and any spline or DD size on the universal joint side of the assembly. Vibration reducers are available in Steel, Stainless Steel and Polished Stainless. Like our needle bearing universal joints our combination vibration reducer will accommodate up to a 35º angle. Rubber Coupling / Rag Joint On some factory applications, a flexible coupling or Rag Joint was used to attach the column to the steering box when there was perfect alignment. If the original column or box is changed, the stock coupling may not work. Borgeson offers the largest variety of spline and DD sizes to fit most applications. Flexible couplings are only available in steel and should only be used when there is a perfect alignment between the connecting shaft and steering box.
