Quarter Master® Aluminum Driveshafts feature unsurpassed strength and smooth, vibration-free performance. Quality material selection, rigid tolerances, careful attention to detail during assembly and a balance spec to less than .125 inch-ounces separate the best from the rest.
Our revolutionary Aluminum Driveshafts are built with a two-part, weld-free assembly process that eliminates the distortion and loss of heat treat strength caused by welding. Hardcoat-anodized, forged-aluminum end yokes are interference fit to O.D. ground 3.0″ x .120″ aerospace aluminum tube. Heavy-duty racing u-joints and a quality slip yoke are then installed. Finally, the assembly is computer balanced. These shafts weigh 40 percent less than their steel counterparts.
